    摘要： 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).

    摘要： A sand control screen assembly (40) and method for treating formations traversed by a wellbore (34) in a single trip are disclosed. The sand control screen assembly (40) includes a base pipe (56) with a plurality of openings (58) that allow fluid flow therethrough. A filter medium (62) is positioned about the exterior of the base pipe (56) to filter particulate matter out of the production fluids. One-way valves (70) are operably associated within the openings (58) of the base pipe (56) to prevent fluid flow from the interior of the base pipe (56) to the exterior of the base pipe (56) during a treatment process. The one-way valves (70), however, are actuatable to allow fluid flow from the exterior of the base pipe (56) to the interior of the base pipe (56) to allow production of fluids from the formation (14).

    摘要： The present invention provides a gravel pack assembly for use in a wellbore having a packer positioned therein with a minimum inside diameter and a primary packing seal. In one embodiment, the gravel pack assembly comprises a pack-off conduit that is coupable to the packer. The pack-off conduit has a maximum outer diameter that is sufficient to prevent the pack-off conduit from traversing the minimum inside diameter of the packer. The gravel pack assembly further includes a seal positioned about an inside diameter of the pack-off conduit. The seal is engageable with an outer surface of a tool that is passable through the pack-off conduit to inhibit fluid flow between the seal and the tool, uphole from the primary packing seal. The primary packer seal is typically near the uphole end of the packer and is the seal that isolates the downhole zones from the pressure exerted by the fluid uphole from the primary packer seal.

    摘要： A running tool includes subassemblies which release the running tool from the liner hanger in response to application of alternating tensile and compressive forces after application of left-hand torque. A running tool includes subassemblies which set the liner hanger in response to left-hand torque followed by increased pressure, and in response to increased pressure without prior left-hand torque being applied. A running tool includes threaded connections, without torque transmitted through the running tool being transmitted by the threaded connections. A method of setting a liner hanger includes applying a compressive force to the running tool; then applying left-hand torque to the running tool; and then applying a tensile force to the running tool. A method of releasing a liner hanger includes applying left-hand torque to the running tool; and then releasing the running tool from the liner hanger by applying a tensile force to the running tool.

    摘要： A well tool is disclosed, which includes features that enhance the reliability and safety of wellsite operations. In one disclosed embodiment, a pressure relief device is incorporated in a well completion tool. The pressure relief device is in fluid communication with fluid delivery and return flowpaths of the tool. When a predetermined differential fluid pressure is experienced, the pressure relief device opens and permits fluid flow between the fluid delivery and return flowpaths. Associated methods of protecting well tools are disclosed as well.

    摘要： Apparatus for completing a subterranean well and associated methods provide economical and efficient well completions. In one described embodiment, a well completion apparatus includes a packer which is settable by application of a compressive axial force thereto. The packer sealingly engages a wellbore of the well when set therein, but does not anchor to the wellbore. The apparatus further includes a screen and an attachment device. The attachment device permits the apparatus to be attached to another packer previously set and anchored within the wellbore.
