A technique for providing auxiliary conduits in multi-trip completions is disclosed. The technique has particular applicability to liner mounted screens which are to be gravel packed. In the preferred embodiment, a protective shroud is run with the gravel pack screens with the auxiliary conduits disposed in between. The auxiliary conduits terminate in a quick connection at a liner top packer. The gravel packing equipment can optionally be secured in a flow relationship to the auxiliary conduits so as to control the gravel packing operation. Subsequent to the removal of the specialized equipment, the production tubing can be run with an auxiliary conduit or conduits for connection down hole to the auxiliary conduits coming from the liner top packer for a sealing connection. Thereafter, during production various data on the well can be obtained in real time despite the multiple trips necessary to accomplish completion. The various completion and/or production activities can also be accomplished using the auxiliary conduits such as actuation of down hole flow control devices, chemical injection, pressure measurement, distributed temperature sensing through fiber optics, as well as other down hole parameters.

A sand control screen assembly (200) positionable within a production interval of a wellbore that traverses a subterranean hydrocarbon bearing formation comprises a base pipe (202) having openings (204) in a sidewall section thereof that allow fluid flow therethrough. A filter medium (210) is positioned about the exterior of at least a portion of the base pipe (202). The filter medium (210) selectively allows fluid flow therethrough but prevents the flow of particulate of a predetermined size therethrough. A seal member (218, 220, 222) is operably associated with the base pipe (202). The seal member (218, 220, 222) has a one-way valve configuration and a valve open configuration such that the seal member (218, 220, 222) controls fluid flow through the openings (204) of the base pipe (202).

A well screen having an internal alternate flowpath for delivering gravel slurry to different levels within a well annulus and a method for assembling same. The screen is comprised of an outer pipe which is concentrically positioned over a base pipe so that an annulus is formed therebetween. Both pipes are perforated along their respective lengths but only part way around their respective circumferences. The respective perforated sections radially align with each other when the pipes are assembled. A plurality of longitudinal ribs isolate the annulus adjacent the perforated sections (i.e. production side of screen) from the annulus adjacent the non-perforated sections (i.e. alternate flowpath side of screen). At least one outlet is provided through the non-perforated section of the outer pipe to provide an outlet from the internal alternate flowpath.

A flow control apparatus (800) includes a tubular member (818) having a plurality of openings (820, 822, 824, 826) that allow fluid flow between an exterior and an interior flow path (828) of the tubular member (818) and a multi-stage flow restricting section (804) operably positioned in a fluid flow path between a fluid source disposed exteriorly of the tubular member (818) and the interior flow path (828). The flow restricting section (804) including a plurality of flow restricting devices (838, 844, 850) each operable to create a pressure drop. Actuatable devices (830, 832, 834, 836) operably associated with the openings (820, 822, 824, 826) are sequentially actuatable to allow fluid flow through the associated openings (820, 822, 824, 826), thereby sequentially reducing the pressure drop experienced by fluids flowing from the fluid source to the interior flow path (828).

A reconstitution device is disclosed and includes a first container receiver having a first component cannula disposed therein, the first component cannula having a withdrawal port and a first transfer port formed thereon, a second container receiver having a second component cannula disposed thereon, the second component cannula having a vent port and a second transfer port formed thereon, a device body coupling the first container receiver to the second container receiver and having a transfer lumen formed therein, the transfer lumen in fluid communication with the first and second transfer ports, a selectively sealing interface secured to the device body and in fluid communication with the withdrawal port, and a venting member in communication with the vent port through a vent lumen.

A flow conduit having at least one orifice is placed in the vicinity of a flow source, which in one non-limiting embodiment may be a hydrocarbon reservoir. The flow pathway between the orifice and the source is temporarily blocked with a degradable barrier. Once the flow pathway is physically placed, the degradable barrier is removed under the influence of an acid, a solvent, time and/or temperature. The flow source and the flow pathways are at least partially covered (and flow blocked by) a temporary coating such as a pseudo-filter cake formed by a viscoelastic surfactant-gelled aqueous drill-in fluid, and the flow conduit is extended to the flow source. The pseudo-filter cake is removed when viscosity is reduced by an internal breaker, and flow is then allowed. The method is useful in one context of recovering hydrocarbons where the flow conduit is a telescoping sleeve or tube that contacts the borehole wall.

Methods and apparatus for extracting liquid water from ambient air, including ambient air in severely arid and hot climates, are described. An example apparatus uses a sorption-desorption-condensation cycle using a sorption wheel to extract moisture from ambient air and concentrate the water vapor driven off from the sorption material in a circulating gas, with condensation of liquid water from the circulating gas.

A filtering apparatus for use in a hydrocarbon producing well for reducing water production therein includes a filtering medium treated with a relative permeability modifier such that the relative permeability modifier reduces the permeability of the filtering medium if the relative permeability modifier contacts water production. The relative permeability modifier may be used to treat a metal portion of the filtering medium in the case of a wire wrap screen or a wire mesh screen or may be use treat a metal portion or the prepacked component of a prepacked screen. The relative permeability modifier may be a polymer of at least one hydrophilic monomer and at least one hydrophobically modified hydrophilic monomer, a hydrophobically modified polymer, a hydrophobically modified water-soluble polymer, hydrophobically modified copolymers thereof or the like.

A flow arrangement (10, 12) for use in a well through one or more underground reservoirs, and where the arrangement (10, 12) is designed to throttle radially inflowing reservoir fluids produced through an inflow portion of the production tubing in the well, the production tubing in and along this inflow portion being provided with one or more arrangements (10, 12). Such an arrangement (10, 12) is designed to effect a relatively stable and predictable fluid pressure drop at any stable fluid flow rate in the course of the production period of the well, and where said fluid pressure drop will exhibit the smallest possible degree of susceptibility to influence by differences in the viscosity and/or any changes in the viscosity of the inflowing reservoir fluids during the production period. Such a fluid pressure drop is obtained by the arrangement (10, 12) comprising among other things one or more short, removable and replaceable flow restrictions such as nozzle inserts (44, 62), and where the individual flow restriction may be given the desired cross section of flow, through which reservoir fluids may flow and be throttled, or the flow restriction may be a sealing plug.
