| 20090084556 | Apparatus for adjustably controlling the inflow of production fluids from a subterranean well - A flow control apparatus ( | 04-02-2009 |
| 20100000742 | EXPANDED NON-BONDED MESH WELL SCREEN - An expanded non-bonded mesh well screen. A method of manufacturing a well screen includes the steps of: expanding at least a portion of a screen jacket; and then securing the screen jacket onto a base pipe. A well screen system includes a base pipe and an at least partially expanded screen jacket surrounding the base pipe. The screen jacket is expanded prior to being positioned on the base pipe. | 01-07-2010 |
| 20100051271 | Sand Control Screen Assembly and Method For Use of Same - A sand control screen assembly ( | 03-04-2010 |
| 20100252250 | Well Screens Constructed Utilizing Pre-Formed Annular Elements - Construction of well screens utilizing pre-formed annular-shaped elements. A well screen includes a filter layer configured to filter fluid flowing through the well screen and a drainage layer which radially supports the filter layer, the drainage layer including multiple individual annular-shaped elements Another well screen includes a drainage layer configured to support the filter layer, with the drainage layer including at least one cavity molded therein. Another well screen includes a base pipe and a layer made up of multiple individual annular-shaped elements stacked coaxially on the base pipe. A cavity is formed in at least one of the elements. | 10-07-2010 |
| 20100258301 | Securing Layers in a Well Screen Assembly - A well screen assembly includes an elongate base pipe, a shroud layer about the base pipe, and a mesh layer between the shroud layer and the base pipe. A portion of the mesh layer overlaps another position of the mesh layer to form an area of overlap. A spine is positioned proximate substantially an entire length of lie area of overlap, and transmits a force from the shroud layer to the mesh layer that compresses and seals the area of overlap against passage of particulate. | 10-14-2010 |
| 20100258302 | Well Screen With Drainage Assembly - A well screen assembly has an elongate base pipe having apertures therein. A filtration layer resides around the base pipe. A drainage assembly resides between the base pipe and the filtration layer. The drainage assembly includes a plurality of elongate risers carried on a mesh. The drainage layer supports the filtration layer apart from the elongate base pipe and defines an elongate passage between the base pipe and the filtration layer that communicates fluid laterally through the drainage assembly. | 10-14-2010 |
| 20110036565 | Control 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 |
| 20110083860 | SAND CONTROL SCREEN ASSEMBLY WITH FLOW CONTROL CAPABILITY - A flow control screen ( | 04-14-2011 |
