Abstract: Method and apparatus for extending the horizontal distance through which wells can be drilled. A horizontal tubular is used to convey a drillstring from a drilling rig toward a target location and a mud return line and pump on the surface is used to pump drilling mud returning from the bit back to the drilling rig.

Abstract: A method and system for transporting fluid is described. The method includes coupling a transit vessel to a terminal vessel associated with at least one terminal. The transit vessel and the terminal vessel are coupled at an open sea or lightering location, which may be selected based upon operational conditions. Then, cryogenic fluid is transferred between the transit vessel and the terminal vessel, while the transit vessel and terminal vessel are moving in substantially the same direction. Once the transfer is complete, the terminal vessel decouples from the transit vessel and moves a terminal to provide the cryogenic fluid to the terminal. The cryogenic fluid may include liquefied natural gas (LNG) and/or liquefied carbon dioxide (CO2).

Abstract: The described invention relates to an integrated LNG re-gasification apparatus suitable for broad use and effective utilization of LNG containers comprising: a) modular storage tank holding structures adapted for storing and accessing LNG containerized in one or more storage tanks; b) a heat exchange re-gasification chamber adapted for converting said LNG to natural gas using a working fluid of higher temperature than the LNG; c) fluid transfer means for transporting the LNG from said storage tanks to the at least one heat exchange re-gasification chamber; d) at least one working fluid holding tank; e) fluid transfer means for transporting the working fluid from said holding tank to the at least one heat exchange re-gasification chamber; f) fluid transfer means for transporting a cooled working fluid, to one or more ancillary refrigeration or air conditioning units.

Abstract: A slip assembly apparatus is adapted (i) to be deployed into a wellbore (ii) to prevent axial movement of a downhole tool assembly in the wellbore when the slip assembly apparatus is actuated and external forces are imposed on the downhole tool assembly; (iii) to allow fluid flow past the slip assembly apparatus within the wellbore when the slip assembly apparatus is actuated or non-actuated; and (iv) to allow release of the slip assembly apparatus by use of a release load that is less than the axial capacity of the deployment mechanism. Different embodiments of the invention contain features such as claddings and treatments for surface hardness and wear resistance, and grooves or flutes for enhancing fluid flow between the outer diameter of the slip assembly and the inner diameter of the well casings.
