166205000 | SCREEN WITH VALVE, CLOSURE, CHANGEABLE RESTRICTOR OR PORTION REMOVABLE IN WELL | 14 |
20090050313 | Viscous Oil Inflow Control Device For Equalizing Screen Flow - A flow balancing system for long screen sections particularly useful in high viscosity hydrocarbon production features an annular flow path whose height and length can be varied to provide a predetermined resistance to a given flow rate of a material of a given viscosity. In assembling a long length of screen sections, greater resistance configurations are placed closer to the wellhead end of the screen section with the more remote sections having progressively less restriction until the furthest section of the screen string where low or no resistance to flow internally to the screen section is offered. | 02-26-2009 |
20110056677 | Well 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 |
20120090831 | Apparatus and Methods for Allowing Fluid Flow Inside at Least One Screen and Outside a Pipe Disposed in an Well Bore - In some embodiments, apparatus for allowing fluid flow inside at least one screen and outside a span of pipe disposed in a well bore includes at least one flow path for fluid entering at least one screen. The flow path extends from the screen(s) along the outside of the pipe to at least one desired entry inlet into the pipe without at least substantial entry at any point therebetween. | 04-19-2012 |
20120097387 | APPARATUS FOR ACTIVATING OR CLEANING FILTER TUBE WELLS - The invention relates to an apparatus ( | 04-26-2012 |
20120160478 | HIGH 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. | 06-28-2012 |
20120175104 | FLOW CONTROL SCREEN FOR USE IN OILFIELD EXPLOITATION - A flow control screen for use in oilfield exploitation comprises: a base pipe ( | 07-12-2012 |
20120186803 | Combined Fracturing Outlet and Production Port for a Tubular String - One or more openings in a zone have an adjacent screen assembly that is axially movable to a position away from the port when pressure in the tubing exceeds the annulus pressure by a predetermined value. Upon the differential being reduced below a predetermined value or when annulus pressure exceeds the tubing pressure, the screen moves over the port to block at least some of the solids in the formation or the well fluids from entering the tubing string. The screen movement can be aided by a bias force and the movement can be locked in to prevent the screen that has moved to a position over the port from moving back away from the port. | 07-26-2012 |
20130032329 | DOWNHOLE FILTER TOOL - Apparatus for downhole filtration of fluids in a wellbore. The apparatus has a diverter and a filter slidably mounted on a mandrel. The diverter has a circumferential wiper element between the mandrel and the casing within which the apparatus is run. When fluids are reverse circulated, or the tool is being pulled out, the diverter shifts to a downward position, wherein it seals against an upper end of the filter, filtering out solids in the fluids and retaining them in a chamber between the sleeve and mandrel. When running the tool into a wellbore, the diverter shifts to an upper position to permit fluids to bypass the filter sleeve. The filter sleeve bears against a spring loaded seat, which permits creating a gap between the diverter and an upper end of the filter sleeve to allow fluids to bypass the filter sleeve should the filter sleeve slots become plugged. | 02-07-2013 |
20140305630 | Flow Control Screen Assembly Having an Adjustable Inflow Control Device - A well system has a fluid flow path for the inflow of production fluid. An inflow control device is disposed within the fluid flow path. The inflow control device has at least first and second fluid passageways. A first plug is disposed within the first fluid passageway and is operable to restrict fluid flow therethrough. The first plug is operably removable from the first fluid passageway responsive to a first stimulus. A second plug is disposed within the second fluid passageway and is operable to restrict fluid flow therethrough. The second plug is operably removable from the second fluid passageway responsive to a second stimulus, wherein the first stimulus is different from the second stimulus. | 10-16-2014 |
20150315881 | Over-Coupling Screen Communication System - A screen system having a first screen sub including a first base pipe wrapped with a first screen section; a second screen sub including a second base pipe wrapped with a second screen section; and a pipe coupling assembly joining the first and second base pipes. A section of filter material extends between the first and second screen sections, and extends over the pipe coupling assembly, thereby forming an annular flow path from the first screen section to the second screen section over the pipe coupling assembly. | 11-05-2015 |
20150330191 | Well Flow Control with Acid Actuator - A well production device includes a production tubing with a fluid passage between the exterior of the tubing and a center bore of the tubing. A fluid barrier is provided sealing the fluid passage. The device has a chamber comprising a dissolving fluid adapted to dissolve the fluid barrier when in contact with the fluid barrier and an actuator configured to release the dissolving fluid into contact with the fluid barrier in response to a signal. | 11-19-2015 |
20160102532 | ENHANCED EROSION RESISTANCE WIRE SHAPES - A filter assembly comprising a tubular member, one or more support members disposed on the tubular member, and a wire disposed on the support members. One or more spaces are formed between adjacent portions of the wire. The wire includes a wire shape having substantially flat side surfaces such that an elongated channel is formed between adjacent wire shapes. | 04-14-2016 |
20160123116 | SYSTEMS AND METHODS FOR MANAGING DEBRIS IN A WELL - Various systems, methods, and devices are disclosed for handling contaminants in a wellbore or riser. A washpipe debris trap (WPDT) traps contaminants traveling up a wellbore from a downhole location, and the WPDT may serve as an indicator for a breached screen in a downhole location. A marine riser reversing tool (MRRT) may reverse the flow of fluid between a workstring conduit and an annulus between the workstring and the wellbore such that fluid rises to the wellhead with greater velocity. A bi-directional chamber trap (BDCT) may be utilized in a wellbore operation to remove contaminants from a fluid. | 05-05-2016 |
20160130908 | ADJUSTABLE ORFICE IN FLOW CONTROL DEVICE (ICD) - An inflow control device (ICD) includes an annular body having an outer surface and an inner surface. An annular recess extends along the inner surface. An opening extends through the outer surface into the annular recess, and a removable orifice plug is arranged in the opening. The removable orifice plug includes a body member having an annular wall including a first end arranged at the outer surface and a second end extending through the annular recess. The removable orifice plug further includes an orifice passage extending into the annular body from the second end and at least one channel extending through the annular wall into the orifice. | 05-12-2016 |
