Description

1 / 28 “METHOD OF FLUID APPLICATION AND METHOD OF ADAPTATION OF A WELL FLUID APPLICATION SYSTEM” FIELD OF TECHNIQUE

[0001] This application relates generally to the operation of reciprocating fluid transfer systems and, more specifically, to providing one or more pulsation control products and / or devices after fluid flow aggregation structures, such as between a vertical pipe and a vertical pipe or after the consolidation of fluid streams from multiple flows, and before connecting to a top drive or articulated joint on a drilling platform and / or other non-traditional locations for pulsation dampers. BACKGROUND

[0002] Pulsation control in fluid transfer systems is constantly in need of improvement. Among the desirable improvements are the reduction of pulsation amplitudes from pumps to the downstream system and increased flexibility in integrating pulsation dampeners with other elements of an overall pump system. 7 SUMMARY

[0003] A fluid application system includes a pulsation damper coupled between a vertical pipe and a vertical pipe or within the vertical pipe or after the consolidation of multi-flow fluid streams or at other locations along the fluid flow path after the vertical pipe or consolidation, but (preferably) before the fluid enters the top drive or articulated joint. Individually or in combination, said pulsation damper “system” device(s) are situated at non-traditional locations along the fluid flow path, but may be used in conjunction with a “main” or conventional pulsation damper at the mud pump outlet, typically acting as a supplementary pulsation damping device(s). Alternatively, one or more pulsation damper system devices may Petition 870260037097, dated 04 / 21 / 2026, page 16 / 66 2 / 28 can be used instead of a pulsation damper conventionally located at the mud pump outlet. Simply put, the pulsation damper system device (or devices) can be an orifice with resistance (e.g., an orifice plate). Alternatively, the pulsation damper system device (or devices) can be an orifice with resistance, coupled to a volume of fluid.

[0004] In some embodiments, the fluid application system includes a pulsation dampening system coupled between a vertical pipe and a vertical pipe. The system includes a fluid reservoir, a fluid pump, piping, a pulsation dampening system, and piping. The fluid reservoir stores a fluid used for a drilling procedure. The fluid pump pumps fluid from the fluid reservoir through the fluid application system. The piping is located downstream of the fluid pump and receives and combines fluids from one or more fluid pumps. The pulsation dampening system receives the combined fluid from the piping and dampens residual pulsations from the piping. The piping receives a fluid output from the pulsation dampening system and transfers the fluid received from the pulsation dampening system further downstream.

[0005] In other embodiments, the fluid application system includes a pulsation dampening system coupled after fittings that combine multiple fluid streams into a single stream are provided. The system includes fittings that combine multiple fluid flow streams into a single flow stream, a pulsation dampening system, and piping. The fluid pump pumps fluid from the fluid reservoir through the fluid application system. The fluid flow stream is combined using fittings located downstream of the fluid pump, which collectively receive and combine fluids from one or more fluid pumps. The pulsation dampening system receives the fluid flow stream and dampens residual pulsations. The piping receives a fluid output from the pulsation dampening system and transfers the fluid received from the dampening system. Petition 870260037097, dated 04 / 21 / 2026, page 17 / 66 3 / 28 of the pulse rate additionally downstream.

[0006] In still other embodiments, the fluid application system includes one or more pulsation dampening systems in the fluid flow path within and / or after the vertical pipe or after the fittings that combine fluid flow streams and, in some embodiments, as close as possible to the top driver or articulated joint of the drilling rig, such as the top driver or articulated joint or in or connected to the inlet pipe for the top driver or articulated joint. Said one or more pulsation dampening systems typically act as supplementary pulsation dampening devices, in addition to a main pulsation dampener at the mud pump outlet and / or a pulsation dampener between the vertical pipe and the vertical pipe or after the fittings that combine fluid flow streams.The system, therefore, may include some combination of: (a) a main pulsation damper at the mud pump outlet; (b) a pulsation damper between the vertical pipe and the vertical pipe or after fittings that combine fluid flow streams; and (c) in embodiments with a vertical pipe and vertical pipe, one or more pulsation dampers in the fluid flow path within and / or after the vertical pipe.

[0007] In an advantageous embodiment, the pulsation damper system makes obvious the need to recharge a gas-charged pulsation damper or replace the compression material within commercially available uncharged pulsation dampers.

[0021] Figures 1 to 13, discussed below, and the various embodiments used to describe the principles of the present disclosure in this patent document are for illustrative purposes only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure can be implemented in any suitably arranged vertical pipe damper or system damper that can be used to control or partially control pulsation amplitudes.

[0022] Reciprocating systems, such as reciprocating pump systems and similar equipment, operate in many types of cyclic hydraulic applications. For example, reciprocating mud pump systems are used to circulate mud or drilling fluid on a drilling rig. Pressure spikes within the pumped fluid accelerate, with each pulsation, the deterioration of the pump, the pump's fluid end expandable parts, and downstream equipment, such as measuring equipment used to determine drilling parameters and a flush pipe and flush pipe packing. Failure to control such pressure spikes inevitably affects the operational performance and service life of the pump, the pump's fluid end expandable parts, and all upstream or downstream components.Pressure spikes can also interfere with instrument signal detection, so failure to control pressure spikes can also affect signal detection and / or signal detection quality in (for example) measurements during drilling operations. Petition 870260037097, dated 04 / 21 / 2026, p. 21 / 66 7 / 28

[0023] Pulsation control equipment is typically positioned immediately upstream or downstream of a reciprocating pump, often with a relative size and configuration proportional to the desired fluid displacement volume per pump stroke and the maximum allocated magnitude of pressure peaks that can be experienced by the pump system during each pulsation. Pulsation control equipment thus assists in reducing pump loads and minimizing pulsation amplitudes to the pump, the pump's fluid end expandable parts, and upstream or downstream equipment. As a result, pulsation control equipment increases the performance and operational life of the pump, the pump's fluid end expandable parts, and any upstream or downstream equipment.

[0024] However, pulsations can also be experienced further downstream of the mud pumps, as the fluid moves through the piping towards its intended destination. These pulsations can be exacerbated when the fluid needs to be diverted to a different path or when multiple fluid streams need to be combined and redirected into a single stream. Most systems do not account for these downstream pulsations. These downstream pulsations can cause damage to downstream components and increased noise for downstream measuring instruments and sensors.

[0025] As used in this document, the “pulsation dampening system” refers to a pulsation dampener installed between a vertical pipe and a vertical pipe, as illustrated by Figures 1 and 2, a combination vertical pipe and pulsation dampening device, as illustrated by Figure 3, a pulse damping pipe illustrated by Figure 4, the orifice-mounted pulsation damping device (or devices) illustrated in Figures 5, 6 and 7, and the system pulsation control dampener located after the location emitting from multiple pumps is consolidated into a flow stream, as Petition 870260037097, dated 04 / 21 / 2026, page 22 / 66 8 / 28 shown in Figure 8.

[0026] Figure 1 illustrates a diagram view of a drilling system 100 that includes a pulsation damper 102 installed between a vertical pipe 104 and a vertical pipe 106, according to various embodiments of the present disclosure. The embodiment of the drilling system 100 illustrated in Figure 1 is for illustration purposes only. Figure 1 does not limit the scope of the present disclosure to any particular implementation of a drilling system.

[0027] Referring now to Figure 1, the drilling system 100 includes at least one pulsation damper 102, at least one vertical pipe 104, at least one vertical pipe 106, at least one mud pump 108, at least one mud well 110, at least one discharge line 112, a pulsation damper 113 conventionally located at the outlet of the mud pump 108, and at least one drilling platform 114. The drilling system 100 operates to pump mud or other fluids into a well currently being drilled to prevent a drill bit 128 from overheating, to provide lubrication to the drill bit, and to remove rock cuttings from the surface.

[0028] A fluid pump or mud pump 108 can pump fluid or mud from a mud well 110 through a discharge line 112 towards a drilling rig 114. More than one mud pump 108 can be used in a drilling system 100 to continue drilling after the failure of a single mud pump 108. A pulsation damper 102 can also be installed in the discharge line 112 for each mud pump 108 to further reduce pulsations. The mud well 110 can also refer to a fluid reservoir, where the fluid reservoir stores fluid used during a drilling process.

[0029] Conventionally, a pulsation damper 113 is located along the discharge line 112, at the outlet of the mud pump 108 and before the vertical pipe 104. The vertical pipe 104 may be Petition 870260037097, dated 04 / 21 / 2026, page 23 / 66 9 / 28 installed below the discharge line 112 and is fixed and / or coupled in fluid communication with the drilling platform 114. The vertical pipe 104 can receive a plurality of different fluid streams from a plurality of mud pumps 108. The vertical pipe 104 can then combine all fluid streams together to send a single fluid stream to the vertical pipe 106. Other functions traditionally performed by the vertical pipe are to provide an auxiliary connection for a supplementary pump and, in systems with multiple vertical pipes that provide operational redundancy in the event of failure of one vertical pipe, to change fluid flow paths from one vertical pipe to another.However, those skilled in the art will understand that some systems dispense with vertical pipe piping, and simply bring the output flows from multiple mud pumps together in a single line near or downstream of the mud pumps, with the combined flow then moving in a single line to the substructure and upwards towards the vertical pipe.

[0030] When fluid streams from multiple mud pumps are combined (in a vertical pipe or without one), pulsations in the resulting combined fluid flow can be amplified based on the different pulsations of the mud pumps 108 being used. For example, different types or sizes of mud pumps 108 can be used in a single drilling system 100, which would cause variations or pulsations in the fluid flow through the pipe. The mud pumps 108 could also be located at different distances from the vertical pipe 104. The mud pumps 108 could start at different times, operating out of cycle with the other mud pumps 108, or they could simply operate at different stroke durations. Any of the above operating parameters would affect the flow of fluids or mud in the vertical pipe 104 causing pulsations in the well.

[0031] The 106 vertical pipe can be installed on the drilling platform. 114 and move to drilling platform 114 to supply the current. Petition 870260037097, dated 04 / 21 / 2026, p. 24 / 66 10 / 28 of fluid flows through a rotating hose 116 connected to a hinged joint 118, the hinged joint 118 being coupled to a rotating hook 120. The vertical pipe 106 receives discharge from the vertical pipe piping, which includes the pulsation dampening system 102. The vertical pipe piping 104 may include multiple discharges to the vertical pipe 106 in the event of failure in part of the vertical pipe piping 104 or associated pipe line.

[0032] The articulated joint 118 can serve as a passage for the fluid stream in a drill rod drive 122 (or simply “drill rod”). The drill rod 122 connects to a drill string 124. The fluid passes through the drill rod 122 and the drill string 124 to the bottom of an unfinished well 126 to a drill bit 128 disposed at a distant end of the drill string 124. The drill rod 122 is typically rotated by a turntable 130. Newer systems may include a top drive for rotating the drill string 124 as an alternative to the turntable and drill rod drive, and the present disclosure is also applicable to such top drive configurations.

[0033] In drilling systems, pulsation dampeners 113 can be installed near the mud pump 108 to reduce pump loads and minimize pulsation amplitudes of the mud pumps 108. However, as the fluid is combined in the vertical pipe 104 into a single stream and sent to the vertical pipe 106, significant energy and pulsation amplitudes can be created by the combination of the mud pump 108 streams or transferred directly to the vertical pipe 106, which is then transferred to the rest of the downstream system described in this document. The pulsation amplitudes produced are greater as more mud pumps 108 are used to supply the fluid reaching the vertical pipe 104, as pulsations from multiple pipes receiving fluid from multiple mud pumps 108 come together and accumulate in the vertical pipe, which are then transferred to the vertical pipe 106. Said pulsations Petition 870260037097, dated 04 / 21 / 2026, page 25 / 66 11 / 28 can cause wear and damage to components, including connections near the articulated joint 118, the drill rod 122, and other components such as a flush pipe and a flush pipe packing (seals) (both not shown) that serve as a conduit for fluid through the articulated joint 118. Instruments used to monitor and measure operations while drilling is occurring can also be affected by residual pulsations from the mud pump 108. Even the smallest pulsations from the vertical pipe tubing can affect measurement readings.

[0034] An additional pulsation damping system 102 is thus installed between the vertical pipe 104 and the vertical pipe 106 to reduce residual pulsations from the mud pump 108 and to reduce pulsations from the combination of fluid streams in the vertical pipe 104. The pulsation damping system 102 reduces pulsations and, similar to the conventional pulsation damper 113 and every other pulsation system damping device (or damping devices) described herein, may produce an internal or external pressure drop within the passing fluid in order to further reduce high-frequency pulsations and improve overall damping performance. In some embodiments, the pulsation damping system 102 may be a gas-charged damper.The pulsation damping system 102, similar to the conventional pulsation damper 113 and any other pulsation system damping device (or damping devices) described herein, may be a hydropneumatic or gas-charged pressure vessel containing compressed air or nitrogen and a bladder (or bellows) separating the process fluid from the gas charge. In some embodiments, the pulsation damping system 102, similar to the conventional pulsation damper 113 and any other pulsation system damping device (or damping devices) described herein, may be a ball-type or cylindrical-type through-fluid damper. In some embodiments, reactive dampers may be used which depend on the compressibility of the fluid. Petition 870260037097, dated 04 / 21 / 2026, page 26 / 66 12 / 28 of process contained within the damper housing and a resistance device fitted with or into the pulsation damper to dampen pump pulsations.

[0035] The pulsation damper system 102 can be installed to the vertical pipe 104 by means of a hose connection. The pulsation damper system 102 may have a flanged outlet connection, and a hammer flange union adapter may be used to connect the pulsation damper 102 to the vertical pipe 104. The pulsation damper system 102 can also connect to the vertical pipe 106 by means of a hose connection.

[0036] The pulsation damper system 102 installed before the vertical pipe 106 reduces high and low frequency pulsation magnitudes to allow the flushing pipe and packing, as well as other components, to last longer. Additionally, the pulsation damper system 102 reduces noise and pulsation levels to allow easier signal detection via the Measurements During Drilling (MWD) and Logging During Drilling (LWD) control located on the drilling platform 114. The pulsation damper system 102 also assists with reduced interference with in-well instruments that may collect residual pulsations and separates detections and data generated from the in-well instruments.

[0037] Figure 2 illustrates a diagram view of a fluid application or drilling system 200 that includes a plurality of mud pumps 208, according to various embodiments of the present disclosure, which can be used in embodiments of a drilling system 100 that includes a pulsation damper system 102 installed between a vertical pipe 104 and a vertical pipe 106, as represented in Figure 1. That is, except for the replacement of the components in Figure 1 with their counterparts, represented in Figure 2, the remainder of the drilling system for the embodiments, according to Figure 2, can conform to the structures Petition 870260037097, dated 04 / 21 / 2026, page 27 / 66 13 / 28 additional features are represented in Figure 1. The drilling system embodiment 200 illustrated in Figure 2 is for illustration purposes only. Figure 2 does not limit the scope of the present disclosure to any particular implementation of a drilling system.

[0038] Referring now to Figure 2, the fluid application and / or drilling system portion 200 for fluid application, drilling or both, which includes at least one pulsation dampening system 202, at least one vertical pipe 204, at least one vertical pipe 206 and a plurality of mud pumps 208. The components of the drilling system portion 200 may be used in place of the similar components of the drilling system 100 illustrated in Figure 1.

[0039] A pulsation damper system 202 is installed between a vertical pipe 204 and a vertical pipe 206. A plurality of mud pumps 208 can transfer fluid to a vertical pipe 204 simultaneously, creating vibrations in the vertical pipe 204. The pulsation damper 202 can be installed in a similar manner to that described herein with respect to the pulsation damper 102, serving to alleviate pulsations generated by the plurality of mud pumps 208 as the fluid enters and intersects within the vertical pipe 204 and is combined into a single output stream.

[0040] Figure 3 illustrates a diagram view of a portion 300 of a system for fluid application, drilling or both, which includes a combination vertical pipe and a pulsation dampening device 302, according to various embodiments of the present disclosure, which can also be used in embodiments of a drilling system 100 that includes a pulsation dampener 102 installed between the mud pump (or pumps) and a vertical pipe, as represented in Figure 1. That is, except for the replacement of the components in Figure 1 with their counterparts, represented in Figure 3, the remainder of the drilling system for the embodiments, according to Figure 3, can conform to the structures Petition 870260037097, dated 04 / 21 / 2026, page 28 / 66 14 / 28 additional features are represented in Figure 1. The 300 drilling system embodiment illustrated in Figure 3 is for illustration purposes only. Figure 3 does not limit the scope of the present disclosure to any particular implementation of a drilling system.

[0041] Referring now to Figure 3, the fluid application and / or drilling system portion 300 includes at least one combination vertical pipe and a pulsation damper device 302, a plurality of mud pumps 304, at least one vertical pipe 306.

[0042] Vertical pipe tubing can increase pulsations experienced by a drilling system because vertical pipe tubing typically has connections or piping that receive fluid from multiple directions from different mud pumps. Vertical pipe tubing often has angled bends that each fluid stream must travel through before the vertical pipe tubing combines the diverging streams into a single stream. As fluid enters the tubing and is transferred through the bends of the vertical pipe tubing, additional vibrations can be created.

[0043] The vertical combination pipe and pulsation damper device 302 can be used instead of a vertical pipe. Instead of diverging separate fluid streams into a single stream with rigid turns, fluids can be received and handled within the body of the vertical combination pipe and pulsation damper device 302. Pulsation dampers often have a volume of space or reservoir within the damper where a certain amount of fluid can accumulate and pulsations are reduced before moving out of the pulsation damper. The vertical combination pipe and pulsation damper device 302 can receive separate fluid streams from a plurality of slurry pumps 304. The vertical combination pipe and pulsation damper device 302 can have piping mounted externally. Petition 870260037097, dated 04 / 21 / 2026, p. 29 / 66 15 / 28 of the surface of the vertical combination pipe and pulsation damper device 302. In the case of a ball-type or cylindrical-type pulsation damper, the piping can be mounted at a selected location on the spherical or cylindrical body of the pulsation damper. The fluid received by the vertical combination pipe and pulsation damper device 302 can be deposited in the interior volume of the vertical combination pipe and pulsation damper device 302, and the fluid within the interior volume of the vertical combination pipe and pulsation damper device 302 would exit the vertical combination pipe and pulsation damper device 302 to move to the vertical pipe 306.The vertical pipe combination and pulsation dampening device 302 can align with the different incoming fluids to control pulsations to be reduced in the combination, such as by creating a rotation within a chamber.

[0044] Since the combination vertical pipe and pulsation damping device 302 includes an interior volume, the problems of using a vertical pipe can be avoided. The combination vertical pipe and pulsation damping device 302 has no bends, like a vertical pipe, reducing vibrations created as separate streams intersect, and the combination vertical pipe and pulsation damping device 302 also provide pulsation damping effects as they receive separate fluid streams.The separate fluid streams can thus be combined within the volume of the vertical combination pipe and pulsation dampening device 302, and then the single combined stream can exit the vertical combination pipe and pulsation dampening system device 302 to move to the vertical pipe 306 with minimal or reduced energy being transferred to the vertical pipe 306 and the rest of the downstream components.

[0045] Figure 4 illustrates a vertical pipe combination and Petition 870260037097, dated 04 / 21 / 2026, page 30 / 66 16 / 28 a pulsation dampening device 400, according to various embodiments of the present disclosure, which can be used in embodiments of a drilling system 100 that includes a pulsation dampener 102 installed between the mud pump (or pumps) and a vertical pipe, as represented

[0046] In Figures 1 to 3 or in modalities of a drilling system 100 which include a pulsation dampener 302 installed after fittings that combine multiple fluid flow streams, as represented in Figure 8. The embodiment of the vertical pipe combination and pulsation dampener device 400 illustrated in Figure 4 is for illustration purposes only. Figure 4 does not limit the scope of the present disclosure to any particular implementation of a pulsation dampener or pulsation dampening method.

[0047] Referring now to Figure 4, the vertical combination pipe tubing and the pulse damper device 400 can be used in the 100, 200 and 300 systems described in this document. The pulse damper tubing includes a body 402. The body 402 illustrated in Figure 4 is a spherical or cylindrical body, in accordance with various pulse dampers that have a ball-type or cylindrical-type body. However, different body shapes can be used to allow for different pulse damper body shapes, such as those shown in Figures 1 to 3.

[0048] The pulsation damper tubing 400 can also include a reservoir 404 inside the interior of the body 402.Reservoir 404 can collect a fluid volume 406 from mud or fluid pumps residing upstream, through a plurality of upstream connections 408, in a fluid application or drilling system, such as those described with respect to Figures 1 to 3. The fluid received from each of the upstream connections 408 are combined as fluid volume 406. At least a portion of fluid volume 406 can then exit the pulse damper tubing 400 as a single fluid stream through a downstream connection 410. The vertical combination tubing and damper device... Petition 870260037097, dated 04 / 21 / 2026, page 31 / 66 The 17 / 28 pulsation 400 can thus completely replace a vertical pipe, reducing vibrations created by multiple fluid streams moving through a vertical pipe, and providing pulsation damping for all streams entering the combination vertical pipe and the pulsation damper 400 device.

[0049] Figure 5 is a diagram view of a drilling system that includes an alternative system pulsation damper mechanism (or mechanisms) that may be installed in, near, or downstream of a vertical pipe, according to various embodiments of the present disclosure. The drilling system embodiment 500 illustrated in Figure 5 is for illustration purposes only. Figure 5 does not limit the scope of the present disclosure to any particular implementation of a drilling system.Although Figure 5 does not represent a conventional pulsation damper located at the mud pump(s) outlet or a pulsation damper system between the vertical pipe and the vertical pipe, those skilled in the art will recognize that one or more of the pulsation damper system(s) represented diagrammatically in Figure 5 can be used without such pulsation dampers, with the conventional or system pulsation dampers described above, or with such conventional or system pulsation dampers.

[0050] In the system of Figure 5, pulsation damping is provided or enhanced by one of several different types of orifice designs positioned at one or multiple locations in or near the vertical pipe 506 or in the fluid flow path after the vertical pipe. The one or more orifice assemblies 502a, 502b, 502c, 502d, . . ., 502n, each comprising a system pulsation damping device (or devices), may be located at different points within the fluid flow path. The pulsation damping orifice assembly may be located within or connected to the inlet pipe for the top actuator or articulated joint (depending on the type used by any given platform), as Petition 870260037097, dated 04 / 21 / 2026, page 32 / 66 18 / 28 illustrated by orifice assembly 502a. The pulsation damping orifice assembly may be located between hose 516 and the inlet pipe end for the top actuator or articulated joint, as illustrated by orifice assembly 502b. The pulsation damping orifice assembly

[0051] may be located at a point just after vertical pipe 506, between the end of vertical pipe 506 and the beginning of hose 516 connecting vertical pipe 506 to the top actuator or articulated joint (depending on the type used by any given platform) as illustrated by orifice assembly 502c. Alternatively, the pulsation damping orifice assembly may be located further along the hose / piping system, as illustrated by orifice assembly 502d. In yet another alternative, the pulsation damping orifice assembly may be located on vertical pipe 506 located next to the drilling tower, possibly at or near an end of vertical pipe 506 (although it may be positioned anywhere along the length of vertical pipe 506), as illustrated by orifice assembly 502n.A single pulsation damping orifice assembly may be employed, or multiple pulsation damping orifice assemblies may be used at different locations along the fluid flow path, including one at each of the locations shown in Figure 5, or multiple pulsation damping orifice assemblies within the top actuator or hinged joint inlet pipe (in the region of orifice assembly 502a), between the hose and the top actuator or hinged joint inlet pipe (in the region of orifice assembly 502b), between the vertical pipe 506 and the hose 516 (in the region of orifice assembly 502c), multiple pulsation damping orifice assemblies in the hose 516 (in the region of orifice assembly 502d), and / or multiple pulsation damping orifice assemblies in the vertical pipe 506 (in the region of orifice assembly 502n). Those skilled in the art will recognize that several... Petition 870260037097, dated 04 / 21 / 2026, page 33 / 66 19 / 28 permutations of the number and location of pulsation damping orifice assemblies may be suitable for different applications. Pulsation damping orifice assemblies may also be positioned in locations other than those in Figure 5, such as the end (outlet) of the vertical tube or at the connection to the articulated joint or top actuator for the hose connected to the vertical tube. As noted earlier, each pulsation damping orifice assembly may produce an internal or external pressure drop in the fluid passage to improve damping of higher frequency pulsations. Said orifice assemblies may or may not include liquid volumes to further improve performance.

[0052] In an advantageous embodiment, the pulsation damper system makes obvious the need to recharge a gas-charged pulsation damper or replace the compression material within commercially available uncharged pulsation dampers. The system 500 retains at least the housing 1001 and a cover 1002 of a gas-charged pulsation damper 501 of the type represented in Figures 10A to 10C. Notably, gas-charged pulsation dampers are typically positioned above the piping through which the pumped fluid passes using a crossing, although said manner is not shown for the pulsation damper system 501 in Figure 5. The cross-sections of a gas-charged pulsation damper are represented in Figures 10A to 10C.As shown in Figure 10A, the gas-charged pulsation damper 1000 includes a housing body 1001 having an upper opening that receives and is sealed by a cover 1002, which combine to form an internal cavity 1003 connected to the pump system fluid piping (not shown) via a lower opening 1004. A flexible inner bladder 1005 within the internal cavity 1003 is filled with a compressible gas. Fluid from the connected piping enters and / or exits the cavity 2003 via the lower opening 1004. A. Petition 870260037097, dated 04 / 21 / 2026, page 34 / 66 20 / 28 pressure of said fluid and the pressure of the compressible gas within the bladder 1005 will cause the lower surface of the bladder 1005, which is in contact with the pump system fluid, to shift and the volume occupied by the gas within the bladder 1005 to change. High pump fluid pressure will cause the bladder 1005 and the gas within it to be compressed substantially into a smaller volume, while mid-range pressure, or the transition from high to low pressure, will cause the bladder and its gas to expand into a larger volume, and low fluid pressure will allow the bladder 1005 and its gas to expand essentially to a maximum volume permitted by the internal cavity 1003 of the housing body 1001 and the cover 1002. The compressed gas within the bladder 1005 thus acts to absorb pressure pulses within the pump fluid and reduce any peak pressure that may occur.However, the compressed gas must be recharged periodically (e.g., monthly, bimonthly, every four months, or semi-annually). Referring now to Figure 5, instead of recharging bladder 1005, bladder 1005 is simply removed. One or more pulsation system dampers are installed in the location(s) and in the manner discussed above, making obvious the need for the gas-charged pulsation damper 501 and its additional maintenance. In many, if not all, instances, pulsation damping performance can be improved by said replacement.

[0053] Alternatively, the 5 00 system retains at least the accommodation 1001 of the commercially available load-free pulsation damper 501 of the type represented in Figures 11A and 11B. Again, load-free pulsation dampers are typically positioned above the flow line through which the pumped fluid passes, although said manner is not shown for the pulsation damper system 501 in Figure 5. Load-free pulsation dampers are often not as effective at attenuating pressure pulsations as gas-loaded pulsation dampers. Components for load-free pulsation dampers Petition 870260037097, dated 04 / 21 / 2026, page 35 / 66 Commercially available 21 / 28 loads are shown in Figures 11A and 11B. The pulsation damper shown in Figures 11A and 11B does not use a gas-filled bladder. As shown in Figure 11A, the load-free pulsation damper includes a housing 1100. The housing has a removable top portion with inlets and outlets for fluid passage into and out of the housing. A cage 1101 shown (twice) in Figure 11B is suspended within the housing and has an upper projection that is sealed against an interior of the housing 1100. The cage 1101 includes an open top along with openings through the side wall and bottom surfaces thereof (thus forming a “cage” or basket). The cage 1101 holds the compression material 1102 within an interior of the cage. The compression material, in the example shown, comprises a system with layers of compression discs, each segmented into four rounded wedges.As the fluid enters the pulsation damper housing 1100 and passes through the open top and / or openings in the side wall and bottom surface of the cage 1101, the fluid is distributed through the compression material by the pump system which operates at a pressure applied by the various surfaces of the compression material, causing the compression material to compress under pressure and thus attenuating the pressure spikes.

[0054] Although free of loads (i.e., not requiring the recharging of a gas medium, as is necessary with gas-filled bladders), the pulsation damper of Figures 11A and 11B is not maintenance-free. After a period of operation (e.g., 12 months), the compression material 1002 may become clogged with and / or deformed by sludge and will typically require replacement due to loss of elasticity and / or accumulation of particulate matter within the pulsation damper, which necessitates shutting down the pump system. Furthermore, the compression material (or materials) is typically manufactured and selected for operation within a specific or predetermined pressure range. Changes in system operating pressure Petition 870260037097, dated 04 / 21 / 2026, page 36 / 66 22 / 28 nominal, when intentional or resulting from a change in operating conditions, may necessitate a change in the compression material, similarly requiring the pump system to be shut down. Referring now to Figure 5, when maintenance of the commercially available load-free pulsation damper 501 becomes necessary, instead of replacing the compression material 1102, the seal can be replaced with a packing gland and the compression material 1102 (and also, optionally, the cage 1101) is simply removed. One or more truly maintenance-free pulsation system dampers are installed in the location(s) and manner discussed above, making obvious the need for the commercially available load-free pulsation damper 501 and its additional maintenance. In many, if not all, instances, pulsation damping performance can be improved by said replacement.

[0055] Figures 6A to 6E are cross-sectional and side-sectional views, respectively, of a pulsation damping orifice assembly 502x that can be used as any of the orifice assemblies 502a, 502b, 502c, 502d, and / or 502n to implement one or more system pulsation damping devices. As illustrated in Figure 6A, an exemplary pulsation damping orifice assembly 502x includes a small enlarged volume, which can be formed (for example) by inserting a pipe segment 622 that has an internal diameter larger than (as small as 2.54 to 5.08 centimeters (1 to 2 inches) larger) the pipe for the fluid flow path before and after the pulsation damping orifice assembly. At the end of the enlarged volume is a pressure drop or fluid flow resistance feature, such as an orifice plate or a drop tube.In the example depicted in Figures 6A and 6B, a 624 or 626 orifice plate (see Figure 6E) is provided. However, those skilled in the art will recognize that a drop tube can be used instead. According to known art, the area... Petition 870260037097, dated 04 / 21 / 2026, page 37 / 66 The 23 / 28 aggregate of openings through the orifice plate 624 or 626 is selected, in combination with the enlarged volume, to dampen pulsations within the fluid flow through the vertical tube 506 and hose 516. As shown in Figures 6C, the orifice plate 624 or 626 may be located at the opposite end (relative to the fluid flow direction) of the enlarged volume formed by the pipe segment 622. Alternatively, the orifice plate 624 or 626 may be located in the middle of the enlarged volume, or anywhere in between. Multiple orifice plates may be arranged within a single enlarged volume. As illustrated in Figure 6D, in a simplified form, the pulsation-damping orifice assembly 502x simply comprises an orifice plate 624 or 626 without any fluid-flow resistance produced by joining or encircling the enlarged volume of the fluid flow path.As illustrated in Figure 6D, the orifice plate 624 may have a plurality of orifices. As illustrated in Figure 6E, the pulsation damping orifice assembly 502x may comprise an orifice plate 626 with a single orifice. As noted previously, orifice assemblies may or may not include liquid volumes to further improve performance. Figures 6A and 6C show an expanded section 622 in which the liquid volume may be contained.

[0056] Figure 7 is a diagram view of an alternative, redundant design for the pulsation damping system device (or devices) that may be installed in, near, or downstream of a vertical pipe, according to various embodiments of the present disclosure for implementing the pulsation damping orifice assembly portion(s) of Figure 5. In the embodiment of Figure 7, a pulsation damping orifice assembly 502x includes a first assembly 701 and a second assembly 702, each including an enlarged volume and an orifice plate, which are provided within each of two parallel fluid flow paths with control valves 703, 704, 705, and 706 (controlled Petition 870260037097, dated 04 / 21 / 2026, page 38 / 66 24 / 28 manually, or under automated control) that control which of the two flow paths is being used. This design provides redundancy in the event of failure of a pulsation damping orifice assembly and, in some high-flow applications, can be used as a low-flow device.

[0057] Figure 8 illustrates a diagram view of a fluid application or drilling system 800 that includes fittings that combine multiple fluid flow streams, according to various embodiments of the present disclosure, which may also be used in embodiments of a drilling system 100 that includes a pulsation damper 102 installed after the fittings that combine multiple fluid flow streams; The drilling system embodiment 800 illustrated in Figure 8 is for illustration purposes only. Figure 8 does not limit the scope of the present disclosure to any particular implementation of a drilling system.

[0058] There is not always a vertical pipe within the fluid flow streams of a drilling rig. Some rigs bring together the various mud pump discharge fluid streams by simple fittings that join multiple fluid streams together into one stream. Referring now to Figure 8, the drilling system 800 includes at least one fitting 802 and / or 804, a plurality of mud pumps 304, and a pipe 806 that receives the combined fluid flow streams.

[0059] The pulsation dampening system device 102, 202, 302, 402 or 502x (pulsation dampening system device 302 shown in Figure 6) can be used inside piping 806 after fittings 802 and / or 804. Pulsation dampeners, such as the pulsation dampening system device 102, 202, 302, 402 or 502x, often have a volume of space, or reservoir, inside the dampener in which a certain amount of fluid can accumulate and pulsations are reduced before moving out of the pulsation dampener. The pulsation dampening system device 102, 202, 302, 402 or 502x can receive the currents Petition 870260037097, dated 04 / 21 / 2026, page 39 / 66 25 / 28 of mud pump discharge fluid. The fluid received by the pulsation dampening system device 102, 202, 302, 402 or 502x may be deposited in the interior volume of the pulsation dampener 102 or 202, of the vertical pipe combination and pulsation dampening device 302, of a pipe pulsation dampener 400, or of the hole-mount pulsation dampening device (or devices) 502x. The fluid within the interior volume of the pulsation dampening system device would exit the pulsation dampening system device to travel to the drilling platform 114 via piping 806. The pulsation dampening system device may control the pulsations to be reduced in the combination, such as by creating a rotation within a chamber.

[0060] Since the pulsation dampening system device includes an interior volume, the problems of using a vertical pipe can be avoided. The pulsation dampening system device does not have bends like a vertical pipe, reducing the vibrations created as the separate streams intersect, and the pulsation dampening system device also provides pulsation damping effects as it receives the combined fluid streams. The combined fluid streams can thus exit the pulsation dampening system device to travel to the drilling platform 114 with minimal or reduced energy being transferred to the rest of the downstream components.

[0061] Figure 9 illustrates a flowchart of a fluid application and pulsation damping process 900 of a fluid application system 100 or 500, according to various embodiments of the present disclosure. For example, the 900 process of Figure 9 can be carried out by a system 100 illustrated in Figure 1 or a system 500 illustrated in Figure 5 or said systems, as modified according to Figure 2, 3 or 4 (without, where appropriate, the steps related to piping). Petition 870260037097, dated 04 / 21 / 2026, page 40 / 66 26 / 28

[0062] Referring now to Figure 9, the process begins at step 902. At step 902, one or more pumps receive fluid from one or more fluid reservoirs, such as the mud well 110 described in this document. At step 904, the one or more fluid pumps send one or more fluid streams downstream through the fluid application system. At step 906, a pipeline receives the one or more fluid streams and combines them into a single fluid stream. At step 908, the pulsation damper receives the single fluid stream from the pipeline.

[0063] In step 910, the installed pulsation dampening system dampens residual pulsations produced by the piping. In some embodiments, the pulsation dampening system may perform damping operations when one or more streams are received in the pulsation dampener, such as when the pulsation dampener is a combination vertical pipe and the pulsation dampening device replaces a vertical pipe in the fluid application system. In step 912, the piping receives fluid emissions from the pulsation dampening system. The piping may, in some embodiments, be a vertical pipe, such as vertical pipe 106. In step 914, the piping transfers the fluid downstream. In step 916, one or more installed pulsation system dampeners dampen any residual pulsations within the fluid flow.

[0064] Figures 12A and 12B are cutaway and diagram illustrations, respectively, of a maintenance-free, reactive pulsation damping system according to embodiments of the present disclosure. Only a few simple, long-wear components are used, allowing for easy renewal and long working cycles without adjustment. The gas charge (i.e., bladder and valves / gauges) or the use of compression materials is eliminated, so maintenance is minimal (e.g., periodic inspection), without the requirement for cover removal. The maintenance-free, reactive pulsation damping system 1200 has no moving parts, with the use of fluid Petition 870260037097, dated 04 / 21 / 2026, page 41 / 66 27 / 28 pumped for pulsation damping. Fluid 1201 with high-magnitude pump pulsations is received through the inlet, and fluid 1202 with low-magnitude pump pulsations is discharged through the outlet, with fluid 1203 within the body reactively damping the magnitude of pump pulsation, i.e., the pumped media reacts with the system fluid mass to reduce pulsation. A removable pressure drop assembly 1204 can contribute to the attenuation of pump fluid pressure pulsations.

[0065] Figure 13 illustrates the installation of a pulsation dampening system, according to embodiments of the present disclosure. In the illustrated example, two three-cylinder pumps that have connected emissions each include a suction stabilizer 1301 connected to the inlet and a gas-charged (or uncharged) pulsation damper 1302 at the outlet. In such configurations, space and support are key and through-flow piping in / out is required. For such gas-mounted appendage units 1301, 1302, the pump racks and piping must be modified and space within the pump room is required. The space and cost of such requirements can be eliminated with the use of a single, suitably installed pulsation dampening system 501.

[0066] To adapt the system of Figure 13, any gas cartridge within the vessels of the suction stabilizers 1301 are removed and (optionally) replaced with an improved cellular tube for load-free operation, without plumbing changes required. Similarly, any gas-filled bladder within the mounted appendage gas dampers 1302 is removed and the vessels allowed to fill with fluid during operation, to provide initial damping control (again, without plumbing changes). Optionally, orifice plates or similar devices may be installed within the flow path after the vessels of the existing mounted appendage gas dampers 1302. An individual reactive pulsation damper system 501 is added. Petition 870260037097, dated 04 / 21 / 2026, page 42 / 66 28 / 28 in the pump system discharge line, connected using a simple connection with the use of high-pressure discharge connectors, to remove persistent pulsations. The 501 pulsation damper system is sized through design analysis and located downstream of the pumps and legacy damping equipment. The 501 pulsation damper system is preferably located where pressure pulsations accumulate (e.g., within a network flow after individual pump emissions are aggregated), and preferably as close as possible to the pump (or pumps).

[0067] Although the present disclosure has been described with exemplary embodiments, various changes and modifications may be suggested for those skilled in the art. It is intended that the present disclosure encompasses such changes and modifications that fall within the scope of the appended claims. Petition 870260037097, dated 04 / 21 / 2026, page 43 / 66
