  • Patent number: 8127831
    Abstract: Method and apparatus for producing hydrocarbons including a wellbore that accesses a subsurface reservoir; a production tubing string disposed within the wellbore; and sand control devices coupled to the production tubing string. At least one of the sand control devices includes a first tubular member having a permeable section and a non permeable section; a second tubular member disposed within the first tubular member. The second tubular member has a plurality of openings and an inflow control device that provides a flow path to the interior. The sand control devices include a sealing mechanism disposed between the first tubular member and the second tubular member to provide pressure loss during gravel packing operations that is less than the pressure loss during production operations.
    Type: Grant

  • Patent number: 7984760
    Abstract: A method, system and apparatus associated with the production of hydrocarbons are described. The system includes a wellbore that accesses a subsurface reservoir; a production tubing string disposed within the wellbore; and one or more sand control devices coupled to the production tubing string and disposed within the wellbore. At least one of the sand control devices includes a first tubular member having a permeable section and a non permeable section; a second tubular member disposed within the first tubular member. The second tubular member has a plurality of openings and an inflow control device that each provide a flow path to the interior of the second tubular member. Also, the at least one of the sand control devices includes a sealing mechanism disposed between the first tubular member and the second tubular member. The sealing mechanism is configured to provide a pressure loss during gravel packing operations that is less than the pressure loss during at least some of the production operations.

  • Publication number: 20070114027
    Abstract: A wellbore apparatus and method for use in a wellbore for completion and production are disclosed. The apparatus comprises an outer permeable material (15) in the wellbore comprising a first basepipe section (11) with at least a portion of the basepipe is perforated (21), the first basepipe is inside the outer permeable material (15) and at least part of the perforated basepipe is designed to be adjacent to a production interval (14), a second basepipe section (10) with at least a portion of the second basepipe is slotted (16), the second basepipe is inside the outer permeable material (15) and above the perforated basepipe section (11) designed to be adjacent to the production interval wherein at least a portion of the slotted basepipe is designed to be adjacent to a non production section of the wellbore. The production completion apparatus may be installed into the wellbore to provide redundancy against well-screen failure.

  • Publication number: 20060237197
    Abstract: A wellbore apparatus and method suitable for either wellbore completions and production. The completion and production apparatus comprises at least one primary flow joint, the primary flow joint comprising at least one three-dimensional surface defining a body capable of fluid flow with at least one permeable surface, and at least one secondary flow joint, the secondary flow joint comprising at least one three-dimensional surface defining a body capable of fluid flow with at least one permeable surface. The method comprises providing a completion and production apparatus comprising at least one primary flow joint and one secondary flow joint wherein multiple fluid flow paths can be provided. The production completion apparatus may be installed into the wellbore to provide at least two flowpaths in the wellbore during well completion, injection and production.

  • Patent number: 5649942
    Abstract: A disposable comedone extractor for use in dermatologic surgery fabricated of a synthetic resin reinforced with natural or synthetic fibers. It has been found that the use of a reinforced synthetic resin ensures that the extractor of the present invention is fully disposable, and thus far less expensive to manufacture and use, as compared to conventional extractors fabricated from metals. In addition, the use of a synthetic resin allows greater control of the flexibility of the extractor as compared to rigid metal extractors.
