Patent application numberDescriptionPublished
20090188154Adjustable-Trigger Gopher Trap - A gopher trap comprising has a first elongated body element pivotally attached at a substantially central point to a second elongated body element, a jaw structure at one end of each of the first and the second body elements such that the jaws close together by relative rotation of the body elements, a spring element placed to urge the first and second body elements apart on a side of the pivot point opposite the jaw elements, a moveable trigger mechanism spanning the two body elements on the jaw side of the pivot point, such that the trigger mechanism holds the jaws open until the trigger mechanism is tripped in a first direction, a tripping mechanism on the jaw side of the pivot point comprising a pivoted paddle extending forward and upward from a paddle pivot joined to one of the body elements, and a trip point that touches the movable trigger mechanism on one side, such that moving the paddle upward moves the trip point in the first direction. With the jaw end of the trap placed in a gopher run, dirt pushed toward the trap will raise the paddle and trip the trigger mechanism, causing the jaws to close with force provided by the spring element urging the body elements apart.07-30-2009

20110308806METHOD AND APPARATUS FOR AUTONOMOUS DOWNHOLE FLUID SELECTION WITH PATHWAY DEPENDENT RESISTANCE SYSTEM - An apparatus is described for controlling flow of fluid in a tubular positioned in a wellbore extending through a subterranean formation. A flow control system is placed in fluid communication with a main tubular. The flow control system has a flow ratio control system and a pathway dependent resistance system. The flow ratio control system has a first and second passageway, the production fluid flowing into the passageways with the ratio of fluid flow through the passageways related to the characteristic of the fluid flow. The pathway dependent resistance system includes a vortex chamber with a first and second inlet and an outlet, the first inlet of the pathway dependent resistance system in fluid communication with the first passageway of the fluid ratio control system and the second inlet in fluid communication with the second passageway of the fluid ratio control system. The first inlet is positioned to direct fluid into the vortex chamber such that it flows primarily tangentially into the vortex chamber, and the second inlet is positioned to direct fluid such that it flows primarily radially into the vortex chamber. Undesired fluids, such as natural gas or water, in an oil well, are directed, based on their relative characteristic, into the vortex primarily tangentially, thereby restricting fluid flow when the undesired fluid is present as a component of the production fluid.12-22-2011

20110036565Control Screen Assembly - Screen assemblies capable of being disposed in a bore for hydrocarbon fluid production are described. The screen assemblies can support filter mediums and reduce or eliminate plugging by swellable material. One screen assembly includes filter mediums supported by a rigid member located exterior to a portion of a base pipe. The rigid member can include openings through which the filter mediums can be in fluid communication with an inner diameter of the base pipe. Swellable material can be disposed exterior to a second portion of the base pipe adjacent to the rigid member. The filter mediums can be displaced to contact a wellbore and the rigid members can help reduce or prevent plugging of screen assembly openings.02-17-2011
20110036567Swellable Screen Assembly - Screen assemblies capable of being disposed in a wellbore for hydrocarbon fluid production are described. The screen assemblies can support tubes for receiving hydrocarbon fluid and reduce or eliminate plugging of the tubes by swellable material. A screen assembly may include a support material between a tube and swellable material located exterior to a base pipe. The tube may include perforations and can receive and direct hydrocarbon fluids from the formation. The swellable material can expand after contact with an activating fluid and can displace the tube toward a surface of the bore. The swellable material can expand more than the support material and the support material can reduce or prevent plugging of the perforations by the swellable material expanding.02-17-2011
20110056677Well Assembly With Removable Fluid Restricting Member - Assemblies that can be disposed in a subterranean bore are described. An assembly can include a fluid restricting member in a groove. At least a portion of the fluid restricting member can be removable from the groove after being exposed to an environment of the bore to form a bypass to a tubing valve. The fluid restricting member may be positioned in a groove located between an inner wall of a base pipe and an outer wall of an assembly housing that is exterior to the base pipe. The fluid restricting member can cooperate with at least part of the tubing valve to block fluid flow and pressure equalization before at least a portion of the fluid restricting member is removed from the grove.03-10-2011
20110083860SAND CONTROL SCREEN ASSEMBLY WITH FLOW CONTROL CAPABILITY - A flow control screen (04-14-2011
20110247833HIGH STRENGTH DISSOLVABLE STRUCTURES FOR USE IN A SUBTERRANEAN WELL - A well tool can include a flow path, and a flow blocking device which selectively prevents flow through the flow path. The device can include an anhydrous boron compound. A method of constructing a downhole well tool can include forming a structure of a solid mass comprising an anhydrous boron compound, and incorporating the structure into the well tool.10-13-2011

20110011586SAND CONTROL SCREEN ASSEMBLY AND METHOD FOR USE OF SAME - A sand control screen assembly (01-20-2011
20110297376Sand Control Screen Assembly Having Control Line Capture Capability - A sand control screen assembly having control line capture capability is operable for use in a subterranean wellbore. The sand control screen assembly includes a base pipe having a screen jacket positioned therearound for preventing the flow of particulate material of a predetermined size therethrough and allowing the flow of production fluids therethrough. The sand control screen assembly also includes a control line capture assembly. The control line capture assembly includes an axially extending flange that couples to the screen jacket and is operable to protect the control line during installation and operation of the sand control screen in the wellbore. The control line capture assembly also includes an axially extending spring channel that couples to the flange. The channel is operable to receive and retain the control line during installation and operation of the sand control screen in the wellbore.12-08-2011
