A wellbore sensing system comprises a wellbore tubular string comprising at least one gauge carrier and at least one adjacent component, and at least one gauge disposed in the gauge carrier. The at least one gauge carrier is configured to provide an annular fluid communication between a housing and a mandrel, and the at least one gauge carrier is sealingly engaged with the at least one adjacent component. The at least one adjacent component comprises at least one of a filter element or a production sleeve, and the at least one gauge is configured to sense at least one parameter within a wellbore.

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).

Inflow control devices for sand control screens. A well screen includes a filter portion and at least one flow restrictor configured so that fluid which flows through the filter portion also flows through the flow restrictor. The flow restrictor includes at least one tube which forces the fluid to change momentum within the tube. An inflow control device for restricting flow into a passage of a tubular string in a wellbore includes at least one flow restrictor configured so that fluid flows between the passage and the flow restrictor. The flow restrictor includes at least one tube which forces the fluid to change momentum within the tube.
摘要:
A packer or bridge plug design is revealed that has a lock mechanism involving the interengagement of teeth. The meshing of the teeth holds the set of the sealing elements and slips of the packer or bridge plug. Release is accomplished by an application of weight which, due to relative movement of parts, allows the stress applied to the slips and sealing element to be relieved with the interengaging teeth of the lock mechanism still in place. Upon stress relief as to the slips and sealing elements, further movement cams the locking member in a manner so as to separate the interengagement of the teeth, thus completing the release. The stress-relief mechanism and the lock mechanism are part of a compact assembly which is preferably mounted above the packer or bridge plug for easy access. A pressure equalization technique involves discrete operation of an equalizing sleeve followed by at least one opposed motion before a release sleeve can be tagged for removing the plug.

A system for installation in a well bore includes a flow control device and a control unit coupled to the flow control device. The flow control device is changeable from a first state to a second state. The first state corresponds to a first mode of fluid communication between an interior of a tubular conduit of a completion string and an annulus between the tubular conduit and a wall of the well bore. The second state corresponds to a second, different mode of fluid communication between the interior of the tubular conduit and the annulus. The control unit is coupled to the flow control device to change the flow control device between the first and second states. The control unit is actuated to change the flow control device in response to pressure in the well bore.

A sand control screen assembly (40) is operably positionable within a wellbore (48). The sand control screen assembly (40) includes a base pipe (42) having at least one opening (60) and an internal flow path (44). A swellable material layer (46) is disposed exteriorly of the base pipe (42). A fluid collection subassembly (50) is disposed exteriorly of the swellable material layer (46). The fluid collection subassembly (50) is in fluid communication with the internal flow path (44). A filter medium (62) is operably associated with the sand control screen assembly (40) and is disposed in a fluid path between the exterior of the sand control screen assembly (40) and the internal flow path (44). In response to contact with an activating fluid, radial expansion of the swellable material layer (46) causes at least a portion of the fluid collection subassembly (50) to contact the wellbore (48).
摘要:
Disclosed is a well screen assembled on a base pipe and having an improved drainage layer disposed between the outer filter material and the base pipe. The improved drainage layer can be formed from a variety of materials and shapes. The drainage layer can be manufactured separately from the base pipe in the form of a tube severed along its length and subsequently assembled on the base pipe.

A sand control screen assembly (60) that is positionable within a wellbore includes a base pipe (62) having at least one opening (64) that allows fluid flow therethrough and a filter medium (66) positioned exteriorly of the base pipe (62) that selectively allows fluid flow therethrough and prevents particulate flow of a predetermined size therethrough. An isolation member (68) is positioned interiorly of the base pipe (62) forming an annulus (84) therewith. A one-way valve (86) is slidably operable within the annulus (84). The one-way valve (86) controls the flow of fluid through sand control screen assembly (60) such that fluid flow is selectively prevented from the interior to the exterior of the sand control screen assembly (60) but is allowed from the exterior to the interior of the sand control screen assembly (60).

A sand control screen assembly (80) that is positionable within a wellbore comprises a base pipe (82) having at least one opening (84) that allows fluid flow therethrough and a filter medium (86) positioned about the exterior of the base pipe (82) that selectively allows fluid flow therethrough and prevents particulate flow of a predetermined size therethrough. An internal isolation member (88) that has at least one opening (90) is positioned within the base pipe (82). A one-way valve (92) is operably associated with the opening (90) of the internal isolation member (88).

A sand control screen assembly (70) is operably positionable within a wellbore (84). The sand control screen assembly (70) includes a base pipe (72) having at least one opening and an internal flow path (74). A swellable material layer (76) is disposed exteriorly of the base pipe (72). A fluid collection subassembly (78) is disposed exteriorly of the swellable material layer (76). A drainage layer (82) is disposed exteriorly of the fluid collection subassembly (78) and the swellable material layer (76). In response to contact with an activating fluid, radial expansion of the swellable material layer (76) causes at least a portion of the fluid collection subassembly (78) and the drainage layer (82) to be displaced toward a surface of the wellbore (84).
