| 166115000 | CENTRAL CHAMBER SEALED WITH RESPECT TO PREPOSITIONED MODIFIED SURROUNDING CONDUIT | 8 |
| 20110067855 | GEOTHERMAL LINER SYSTEM WITH PACKER - A geothermal liner system with packer for sealing a producing zone within a wellbore has a mandrel placed in an interior of the wellbore, a packer releasably affixed around an outer surface of the mandrel, and a sleeve positioned adjacent an end of the mandrel. The liner system is generally tubular and may include joint casings and a mandrel, all being tubular-shaped. The packer is expandable upon exposure to wellbore conditions. The sleeve has perforations in a wall thereof. The mandrel is slidable relative to the packer when the packer expands against the wellbore. The sleeve is selectively controlled to manage production from sealed wellbore zones. The system is stabilized through various wellbore conditions, such as geothermal heat, by being adjustable for thermal expansion of parts of the system. | 03-24-2011 |
| 20140124193 | METAL CHEVRON AXIAL SEAL - A subterranean wellbore assembly includes an outer cylindrical wall and an inner cylindrical wall cooperatively defining an annular space. A seal assembly is disposed within the annular space. The seal assembly includes chevron seals. Each chevron seal includes a central portion and two axially and radially extending wing portions. Chevron seals may be of polymeric PEEK material or of nickel based material. Other seal assemblies may be arranged in the annular space in place of the seal assembly. | 05-08-2014 |
| 20140151024 | Packoff Sealing Assembly - A packoff assembly for sealing a space between an inner well member and an outer well member. The packoff assembly has a packoff body, and a sealing mechanism with a U-shaped cross-section, including a packoff body leg and a well component leg extending substantially downward from a transverse connecting section. The well component leg is elastically bendable so that it resists inward deflection toward the packoff body and so that the sealing mechanism can be set without the use of an energizing ring. The packoff body leg is configured for engagement with the packoff body, and the well component leg has a sealing surface configured for sealing engagement with the inner or the outer well member. | 06-05-2014 |
| 20140262208 | Shunt Tube Connection and Distribution Assembly and Method - A shunt tube assembly comprises a plurality of shunt tubes, a jumper tube, and a coupling member configured to provide fluid communication between the jumper tube and the plurality of shunt tubes. The coupling member can comprise a first end and a second end. The coupling member may be configured to provide a sealing engagement between the coupling member and the jumper tube at the first end, and the coupling member may be configured to provide a sealing engagement between the coupling member and the plurality of jumper tubes at the second end. | 09-18-2014 |
| 20150075772 | System and Method for Separating Gaseous Material From Formation Fluids - There is provided a system for effecting production of formation fluids from a subterranean formation. The system includes a gas anchor for mitigating gas lock. Sealing engagement of the gas anchor against the wellbore tubular is effected without use of a conventional packer, which would otherwise be susceptible to receiving debris deposited from the formation fluid, which thereby results in the packer, as well as the gas anchor, becoming vulnerable to becoming stuck within the wellbore tubular. | 03-19-2015 |
| 166116000 | Surrounding conduit carries packer or plug | 3 |
| 20090242187 | HYDRAULICALLY OPENABLE PORTED SUB - A ported sub comprising: a tubular body including a wall and ends formed for installation in a wellbore tubular string; a first port through the wall; a second port through the wall; a first hydraulically openable sliding sleeve for the controlling the open and closed condition of the first port; a second hydraulically openable sliding sleeve for the controlling the open and closed condition of the second port; a first pressure release connection for securing the first hydraulically openable sliding sleeve in a position on the tubular body and being releasable by application of a selected hydraulic pressure to the first hydraulically openable sliding sleeve; and a second pressure release connection for securing the second hydraulically openable sliding sleeve in a position on the tubular body and being releasable by application of hydraulic pressure at least substantially similar to the selected hydraulic pressure to the second hydraulically openable sliding sleeve, the first pressure release connection including a first type of pressure release mechanism and the second pressure release connection including a second type of pressure release mechanism different than the first type of pressure release mechanism. A tubing string and method may employ the ported sub. | 10-01-2009 |
| 20130146276 | Flow Control Hanger and Polished Bore Receptacle - A completion system is provided for completing downhole wells, comprising an upper polished bore receptacle incorporated into an intermediate casing of the downhole well and formed with a honed inner bore. A bottom packer for supporting a completion string within the intermediate casing has a first sealing assembly for sealing engagement against the inner bore of the upper polished bore receptacle. A lower polished bore receptacle is further incorporated into the intermediate casing and formed with a honed inner bore. A flow control hanger in the form of a hollow mandrel hangs a production liner in the intermediate casing and has a second sealing assembly for sealing engagement against an inner bore of the lower polished bore receptacle. A further completion system is provided comprising a polished bore receptacle (PBR) and a latch down packer having a lower end to which the PBR is connected. | 06-13-2013 |
| 20140262209 | DOWNHOLE SEALING ASSEMBLY - A sealing assembly for sealing an annulus in a downhole application including a sealing ring and a deflecting ring axially aligned between axially opposed mesh back-ups, each of the sealing ring and the deflecting ring defining a first ramped end, the first ramped ends facing each other such that an axial set force applied to the deflecting ring deflects the sealing ring radially outward forcing the sealing ring into a side-by-side arrangement with the deflecting ring to fill and seal the annulus. | 09-18-2014 |
