  • Patent number: 7703538
    Abstract: Access to a downhole tool through a tubular wall is created with a penetration tool into a surrounding annular chamber. The chamber is disposed around a tool joint between the end connection leaving an annular chamber that is of considerable length and allowing penetration anywhere along such length. The need to precisely position the penetration tool, as in past designs of annular chambers disposed within a pin and box connection is eliminated. Landing shoulders for the penetrating tool are also not required as the long length of the annular chamber allows surface personnel to sufficiently and accurately place the penetration tool somewhere along the length of the annular chamber.

  • Patent number: 7543659
    Abstract: A connector connects auxiliary flow lines and electrical lines that extend through and terminate at or near opposing ends of two respective components of a downhole tool string. The connector comprises a body assembly for fluidly-connecting the auxiliary flow lines and electrically-connecting the electrical lines of the respective two components, and an assembly for adjusting the length of the body assembly. The two components are discrete modules of a unitary tool, or alternatively, are distinct tools. Additionally, the connector may include a mechanism for closing the auxiliary flow lines of one or both compartments upon disconnection of the fluid connection between the two components.

  • Publication number: 20090084557
    Abstract: The invention concerns a section of tubing or other conduit having a flow passage. The flow passage extends through the tubing and incorporates a member extending through the passage and guides which constrain a fluid flowing through the flow passage to flow around the member along a path which is longer than an axial length of the flow passage in a fluid flow direction. The guides may define an annular path. The conduit may comprise an inside wall and the guides may comprise a combination of at least one spiral channel defined along the inside wall and the member may be a sucker rod extending along the flow passage.

  • Patent number: 7431093
    Abstract: A protection system for an artificial lift device including but not limited to electrical submersible pump (ESP) and an electrical submersible progressing cavity pup (ESPCP). The artificial lift device is suspended on a tubing string into a wellbore where the artificial lift device contacts well fluids. The artificial lift device is provided with a barrier such as an intake barrier or output barrier that deters an ingress of well fluids into the artificial lift device. As a result, the artificial lift device may remain idle and submerged within well fluids for an extended period of time without experiencing degradation of the artificial lift device internals. The intake barrier may include a plug, burst disk, dissolvable material, a selectively openable barrier such as a sleeve or a spring biased member or other member that is capable of providing a suitable barrier. The barrier may be removed once the artificial lift device is ready for operation.
