Abstract
Description
ATTORNEY DOCKET NUMBER PATENT APPLICATIONVERTICE1410-1 PCT Customer No . 109967METHODS AND SYSTEMS FOR A DOWNHOLE TOOLBACKGROUND INFORMATIONField of the Disclosure
[0001] Examples of the present disclosure relate to downhole tools. More specifically, embodiments are directed towards a drop-off tool with a mechanical packer, wherein the drop-off tool is configured to protect against pre-setting the mechanical packer.Background
[0002] Directional drilling is the practice of drilling non-vertical wells. Horizontal wells tend to be more productive than vertical wells because they allow a single well to reach multiple points across a horizontal axis, covering a larger cross-section of the producing formation without the need for additional vertical wells. This makes each well more productive by reaching reservoirs across the horizontal axis. While horizontal wells are more productive than conventional wells, horizontal wells are costlier. The casing may be run through the drilled horizontal, vertical, or deviated wells to reach the reservoirs across the horizontal axis.
[0003] Well, trajectory complexity, depth, pressure, temperature, and cost have increased the challenges of well construction design, planning, and operations. Long horizontal laterals in unconventional shale wells, liner drilling, extended reach wells, and cemented and uncemented liners require high- performance tubing systems capable of rotation to reach total depth, robust setting mechanisms tolerant of higher solids content, packer sealing elements that can survive run-in hole without being prematurely set, etc.
[0004] However, due to high torque and axial movement being applied to running tools and tubulars, downhole packers may be inadvertently and prematurely set when rotating are axially moving the string.
[0005] Accordingly, needs exist for systems and methods for a drop-off tool with a mechanical packer, wherein the drop-off tool is configured to protect against pre-setting the mechanical packer.ATTORNEY DOCKET NUMBER PATENT APPLICATIONVERTICE1410-1 PCT Customer No . 109967SUMMARY
[0006] Embodiments disclosed herein describe systems and methods for a drop-off tool with a mechanical packer, wherein the drop-off tool is configured to protect against pre-setting the mechanical packer. Embodiments may include a tubular, running tool, float nut, support, and collet.
[0007] The tubular may be a hollow cylinder with a proximal end and a distal end, wherein the tubular is configured to allow fluid and tools to be run within the inner diameter of the tubular. An inner circumference of the tubular may include a groove, profile, etc. (refereed to hereinafter collectively and individually as “groove”), wherein the groove is configured to receive an outer projection positioned on an outer diameter of the proximal end of the collet. When the outer projection is positioned within the groove, the tubular and the running tool may be axially locked. This axial locking may not allow the packer to be prematurely deployed. In embodiments, the tubular may be a polished bore receptacle.
[0008] The running tool may be configured to assist in setting the packer and be retrieved after the setting of the packer is set. The running tool is configured to be positioned within the inner diameter of the tubular. The running tool may have a ledge, temporary coupling mechanisms, and a ratchet mechanism.
[0009] The ledge may be an abutment on the outer diameter of the running tool, wherein the ledge may axially restrict the downhole movement of the float nut.
[0010] The temporary coupling mechanisms may be shear screws, pins, or any other mechanisms configured to temporarily and selectively secure the running tool with the support. After a predetermined amount of force is applied across the temporary coupling mechanisms, the temporary coupling mechanisms may be active and sheared. Upon activation of the temporary coupling mechanisms, the support may axially move in a first, uphole direction relative to a static running tool. In other embodiments, the support and running tool may move uphole together.
[0011] The ratchet mechanism may be a device that is configured to allow the relative movement of the support and the running tool in the uphole direction while restricting the relative movement of the support and the running tool in the downhole direction. More specifically, the outer diameter of the running tool may include a first set of ratchet teeth that are configured to interface with a second set of ratchet teeth that are positioned on the inner diameter of the support. Based on the relative geometries between the first set of ratchet teeth and the second set of ratchet teeth, the support mayATTORNEY DOCKET NUMBER PATENT APPLICATIONVERTICE1410-1 PCT Customer No . 109967 move axially relative to the running tool in a first-uphole - direction by not a second - downhole - direction.
[0012] The float nut may be a fastener that is configured to be dethreaded and axially move uphole by rotating the running tool in the first direction. Responsive to rotating the running tool in the first direction, the proximal end of the float nut may move uphole to apply a force against the support. This force may be sufficient to activate the temporary coupling mechanisms and allow the movement of the support in the uphole direction. In embodiments, the first direction to rotate the float nut may also be a direction to tighten other interfaces within the running tool. Accordingly, while the float nut is moving uphole due to the rotation in the first direction, a set-down force may be maintained by the running tool. This may allow for the simultaneous actions of rotating the running tool in a right-hand motion, which also dethreads the float nut to activate the collet. Therefore, the entire running tool may not be shifted upward or may be shifted downhole due to the rotation in the first direction while the float nut is moving uphole. In embodiments, the float nut may be positioned between the support and the packer.
[0013] The support may be positioned on an outer diameter of the running tool and may be configured to axially move in the uphole direction based on the movement of the float nut. The support may include a first abutment, channel, and second abutment. Before the support is activated, the first abutment may be configured to prop open the head of the collet, such that the head of the collet is embedded within the groove on the inner diameter of the tubular. After activating the support, the head of the collet may be aligned with the channel, axially positioned between the first and second abutment, such that the head of the collet is no longer embedded within the groove within the inner diameter of the tubular. In embodiments, a diameter across the channel may be smaller than a diameter across the first and second abutments. In embodiments, the support and float nuts may be a separate element from the running tool. However, in other embodiments, the support may be a unitary element with the running tool.
[0014] The collet may be a collet, dogs, dies, or any other device (hereinafter collectively and individually referred to as “collet”) that is configured to naturally flex inward to decrease a diameter across a proximal end of the collet when the proximal end of the collet is not supported. The collet may include a distal end, shaft, and proximal end.ATTORNEY DOCKET NUMBER PATENT APPLICATIONVERTICE1410-1 PCT Customer No . 109967
[0015] Before the collet is activated, the distal, downhole end of the collet may be shouldered against a sleeve, which does not allow the collet to axially move in the downhole direction relative to the tubular.
[0016] The shaft may extend from the distal end of the collet to the proximal end of the collet. The shaft may have a tapered inner diameter and a planar outer diameter. The tapered inner diameter increases the thickness of the shaft from the proximal end to the distal end of the collet. This tapering may assist in allowing the collet to naturally flex inward.
[0017] Before activating the collet, the proximal end of the collet is supported by an object, such as the first abutment of the support. When supported, the inner diameter across the proximal end of the collet may be substantially similar to the outer diameter across the first abutment. After the collet is activated, by moving the support, the proximal end of the collet is not supported by the first abutment and is axially aligned with the channel. This may allow the proximal end of the collet to flex inward reducing the inner diameter across the proximal end.
[0018] More specifically, the proximal end of the collet may include an inner projection and an outer projection. The inner projection may have a smaller inner diameter than the shaft of the collet. This may allow the inner projection to be positioned directly against the first abutment before the collet is activated. The outer projection of the collet may have a larger outer diameter than the shaft, which may allow the outer projection to be inserted into the groove of the tubular before the collet is activated. When the outer projection is positioned within the groove, the collet and the tubular may be axially locked. After activating the collet by axially aligning the channel of the support with the proximal end of the collet, the inner projection may flex inward to have a smaller diameter than a diameter across the first abutment and the outer projection may flex inward to have a smaller diameter than the diameter across the tubular. This may allow the collet and the running tool to move axially concerning the tubular.
[0019] After activating the collet, the running tool may be pulled upward, dog collets may shift outward, and the tubular may shift downward.

It will be apparent, however, to one having ordinary skill in the art that the specific detail need not be employed to practice the present invention. In other instances, well-known materials or methods have not been described in detail to avoid obscuring the present invention.ATTORNEY DOCKET NUMBER PATENT APPLICATIONVERTICE1410-1 PCT Customer No . 109967
[0030] Turning now to FIGURE 1, FIGURE 1 depicts a drop-off tool 100 with a mechanical packer 110. The drop-off tool 100 is configured to protect against pre-setting the mechanical packer 110. Embodiments may include a tubular 120, running tool 130, float nut 140, support member 150, and collet 160.
[0031] Tubular 120 may be a hollow cylinder with a proximal end and a distal end, wherein tubular 120 is configured to have tools and fluid run within the inner diameter of tubular 120. An inner circumference of tubular 120 may include a groove 122. Groove 122 may be configured to receive an outer projection 160 positioned on an outer diameter of the proximal end of collet 160. In embodiments, when outer projection 160 is positioned within groove 122, tubular 120 and the packer 110 may be axially locked. This axial locking may prevent packer 110 from being prematurely deployed. In embodiments, tubular 120 may be a polished bore receptacle.
[0032] Running tool 130 may be configured to assist in setting the packer 110 and be retrieved after the setting of the packer 110. Running tool 130 is configured to be positioned within the inner diameter of the tubular 120 when run in the hole, and be pulled out of the hole while the tubular 120 remains downhole. Running tool 130 may have a ledge 132, temporary coupling mechanisms 134, and ratchet mechanism 136.
[0033] Ledge 132 may be an abutment on an outer diameter of the running tool 130, wherein ledge 132 may axially restrict the downhole movement of the float nut 140. In embodiments, ledge 132 may have an outer diameter that is longer than other portions of running tool 130.
[0034] The temporary coupling mechanism 136 may be shear screws, pins, or any other mechanism that is configured to temporarily and selectively secure running tool 130 with the support member 150. Before temporary coupling mechanisms 136 are activated, running tool 130 and support member 150 may be axially locked together. After a predetermined amount of force is applied across the temporary coupling mechanisms, the temporary coupling mechanisms 136 may be activated. Upon activation of the temporary coupling mechanisms 136, support member 150 may axially move in a uphole direction relative to the running tool 130.
[0035] Ratchet mechanism 134 may be a device that is configured to allow the relative movement of support member 150 and running tool 130 in an uphole direction while restricting the relative movement of support member 150 and running tool 130 in a downhole direction. More specifically, the outer diameter of the running tool 130 may include a first set of ratchet teeth that are configured to interface with a second set of ratchet teeth that are positioned on the innerATTORNEY DOCKET NUMBER PATENT APPLICATIONVERTICE1410-1 PCT Customer No . 109967 diameter of the support member 150. Based on the relative geometries between the first set of ratchet teeth and the second set of ratchet teeth the support member 150 may move axially relative to the running tool in the uphole direction but not a downhole direction.
[0036] Float nut 140 may be a fastener that is configured to be dethreaded and axially move in the first direction by rotating the running tool 130 in the first rotational direction. Responsive to rotating the running tool in the first rotational direction, the proximal end of float nut 140 may move uphole to apply a force against the support. This force may be sufficient to activate the temporary coupling mechanisms and allow the movement of the support in the uphole direction. In embodiments, the first rotational direction to rotate float nut 140 may also be a direction to tighten other interfaces within the running tool 130. Accordingly, while float nut 140 is moving uphole due to the rotation in the first rotational direction, a set down force may be maintained by running tool 130. In other words, the entire running tool 130 may not be shifted upward or may be shifting downhole due to the rotation in the first rotational direction while float nut 140 is moving uphole. In embodiments, float nut 140 may be positioned between the support member 150 and the packer 110.
[0037] Support member 150 may be positioned on an outer diameter of the running tool 130 and may be configured to axially move in the uphole direction based on the movement of the float nut 140. In embodiments, support member 150 and running tool 130 may be a unitary piece, wherein the geometry of support member 150 is milled into the outer diameter of running tool 130. In other embodiments, support 150 and running tool 130 may be independent parts, wherein support member 150 may move relative to and independently of running tool 130.
[0038] Support member 150 may include a first abutment 152, channel 154, and second abutment 156. Before the support member 150 is activated, first abutment 152 may be configured to prop open the proximal end 162 of the collet 160, such that the proximal end 162 of the collet 160 is embedded within the groove 122 on the inner diameter of the tubular 120. After activating the support member 150, the proximal end 162 of the collet 160 may be aligned with the channel 152, and positioned between the first abutment 152 and second abutment 156, such that the proximal end 162 of the collet 160 is no longer embedded within the groove 122 within the inner diameter of the tubular 120. In embodiments, a diameter across channel 154 may be smaller than a diameter across the first abutment 152 and the second abutment 156, such that channel 154 forms a reduced inner diameter section. As such, support member 150 may be configured to control the innerATTORNEY DOCKET NUMBER PATENT APPLICATIONVERTICE1410-1 PCT Customer No . 109967 diameter across the proximal end 162 of the collet 160 based on the alignment of the proximal end 162 of the collet 160 and support member 150.
[0039] Collet 160 may be a collet, dogs, dies, any type of retaining means, or any other device (hereinafter collectively and individually referred to as “collet”) that is configured to naturally flex inward to decrease a diameter across a proximal end 162 of the collet 160 when the proximal end 162 of the collet 160 is not supported. The collet 160 may include a distal end 164, shaft 166, and proximal end 162.
[0040] Before collet 160 is activated, the distal end 164 of collet 160 may be shouldered against a sleeve, which does not allow collet 160 to axially move in the downhole direction relative to the tubular 120.
[0041] Shaft 166 may extend from the distal end 164 of the collet to the proximal end 162 of the collet 160. The shaft may have a tapered inner diameter and a planar outer diameter. The tapered inner diameter increases the thickness of the shaft from the proximal end to the distal end of the collet. This tapering may assist in allowing the collet to naturally flex inward.
[0042] Before activating the collet 160, the proximal end 162 of the collet 160 is supported by an object, such as the first abutment 162 of the support 160. When supported, the inner diameter across the proximal end 162 of the collet 160 may be substantially similar to the outer diameter across the first abutment 152. After the collet 160 is activated, by moving the support member 150, the proximal end 162 of the collet 160 is no longer supported by the first abutment 152, and the proximal end 162 is axially aligned with the channel 164. This may allow proximal end 162 to flex inward, reducing the inner diameter across proximal end 162.
[0043] More specifically, proximal end 162 of the collet 160 may include an inner projection and an outer projection. The inner projection may have a smaller inner diameter than the shaft 164 of the collet 160. This may allow the inner projection to be positioned directly against the first abutment 152 before the collet is activated. Moreover, the outer projection of the collet may have a larger outer diameter than the shaft 164, which may allow the outer projection to be inserted into the groove 122 of the tubular 120 before the collet 160 is activated. When the outer projection is positioned within the groove 122, the collet 160 and the tubular 122 may be axially locked. After activating the collet by axially aligning the channel 154 of the support with the proximal end 162 of the collet 154, the inner projection may flex inward to have a smaller diameter than the diameter across the first abutment 152 and the outer projection may flex inward to have a smaller diameter than theATTORNEY DOCKET NUMBER PATENT APPLICATIONVERTICE1410-1 PCT Customer No . 109967 diameter across the tubular 120. This may disengage the collet 160 and the tubular 120, allowing the collet 160 and the running tool 130 to move axially with respect to the tubular 120. After activating the collet 160, the running tool 130 may be pulled upward, dog collets may shift outward, and tubular 120 may shift downward.
[0044] FIGURE 2 depicts an embodiment of drop-off tool 100 with mechanical packer 110. As depicted in FIGURE 2 running tool 130 may include a plurality of segments, which can be tightened by rotating the string in a first rotational direction, which may also axially move the float nut in an uphole direction.
[0045] FIGURE 3 depicts an embodiment of drop-off tool 100 after axially moving float nut 120. As depicted in FIGURE 3, responsive to rotating running tool 130 in a first rotational direction, float nut 120 may be dethreaded, causing float nut 120 to apply an upward pressure against support member 150. When the upward force exceeds a predetermined force threshold, temporary coupling mechanisms 136 may shear, allowing an offset between the distal end of float nut 120 and ledge 132 to increase and correspondingly move support member 150 uphole.
[0046] The uphole movement of support member 150 may cause proximal end 162 of collet 160 to be axially aligned with channel 154.
[0047] FIGURE 4 depicts an embodiment of drop-off tool 100 after axially aligning proximal end 162 of collet 160 with channel 154. When proximal end 162 is no longer propped open by the second abutment 156, the proximal end 162 may flex inward to no longer be positioned within groove 122 of tubular 120. This flexing may allow the outer diameter of the proximal end 162 to be smaller than the inner diameter of tubular 120, and the inner diameter of the proximal end 162 to be smaller than the outer diameter of the first abutment 152 and second abutment 154. This relative movement of the proximal end 162 may cause running tool 130 to no longer be axially locked with tubular 120.
[0048] FIGURE 5 depicts an embodiment of drop-off tool 100 after pulling up running tool 130. As depicted, after running tool 130 is pulled upward, dogs 510 may pass the proximal end 505 of tubular 120. When dogs 510 are no longer constrained by the inner diameter of tubular 120, dogs 510 may flex outward to have an outer diameter that is larger than the inner diameter of tubular 120.
[0049] In embodiments, dogs 510 may be configured to sit on proximal end 505 of tubular 120 above seals if running tool 130 is strung back into tubular 120 to set the downhole packer.ATTORNEY DOCKET NUMBER PATENT APPLICATIONVERTICE1410-1 PCT Customer No . 109967
[0050] FIGURE 6 depicts a method 600 of utilizing a tool configured to prevent premature setting of a downhole device, according to an embodiment. The operations of the method depicted in FIGURE 6 are intended to be illustrative. In some embodiments, the method may be accomplished with one or more additional operations not described, and / or without one or more of the operations discussed. Additionally, the order in which the operations of the method are illustrated in FIGURE 6 and described below is not intended to be limiting. Elements depicted in FIGURE 6 may be described above. For the sake of brevity, a further description of these elements is omitted.
[0051] At operation 610, a running tool and tubular may be run in hole together. When run in hole, a proximal end of a retention element may be engaged with a circumferential profile feature of the tubular, wherein the retention element is radially positioned between the running tool and the tubular.
[0052] At operation 620, the running tool may be rotated in a first direction to move a proximal end of a float nut uphole to apply a force against a support member. The force may be sufficient to activate temporary coupling mechanisms to allow relative axial movement of the support member and retention element.
[0053] At operation 630, the support member may axially move to activate a retention element. When the retention element is activated, the proximal end of the retention element is repositioned within a channel of the support member. The channel being positioned between a first abutment and a second abutment, and has an inner diameter smaller than the inner diameters of the first and second abutments.
[0054] At operation 640, running tool may be moved uphole, and dogs may pass the proximal end of the tubular. When the dogs are no longer constrained by the inner diameter of the tubular, the dogs may radially expand to have an outer diameter that is larger than the inner diameter of the tubular. This will restrict the downhome movement of the running tool.
