Abstract: A slickline that includes both electrically conductive and fiber optic capacity. The slickline includes a fiber optic thread or bundle of threads that may be surrounded by an electrically conductive member such as split half shells of copper elements. Further, these features may be disposed in a filler matrix so as to provide a cohesiveness the core of the slickline. So, for example, the line may be more effectively utilized in downhole applications such as coiled tubing operations, without undue concern over collapse or pinhole issues emerging in the line.

Abstract: A well advisor system and console for monitoring and managing pressure testing operations at a well site. The system may be accessed through one or more workstations, or other computing devices, which may be located at a well site or remotely. The system is in communication with and receives input from various sensors. It collects real-time sensor data sampled during operations at the well site. The system processes the data, and provides nearly instantaneous numerical and visual feedback through a variety of graphical user interfaces (“GUIs”), which are presented in the form of an operation-specific console. The input and data provides information related to pressure testing at a well site.

Abstract: A pipe assembly used in horizontal directional drilling operations. The pipe assembly has an outer member, an inner member, and first removable collar. The inner member has a polygonal outer profile of uniform shape along its length and is partially contained within the outer member. The first removable collar is supported on the inner member within the outer member and limits relative axial movement of the inner member and the outer member.

Abstract: The present invention relates to a method and apparatus for cleaning an oil and gas well riser section or assembly. Even more particularly, the present invention relates to an improved method and apparatus for cleaning oil and gas well riser sections wherein a specially configured cap or pair of caps are fitted to the ends of the riser which enable pressure washing cleaning tools (or a camera) to be inserted into and through the riser cleaner fluid continuously recirculates so that relatively small volume of cleaning fluid (for example between about 700 and 1,000 gallons) is required. The cleaning process uses a volume of cleaning fluid that is discharged from the riser pipe at a relatively high temperature of about between 100 and 180° F. Such a high temperature cleaning fluid could possibly damage the pump that is used for supplying pressurized fluid to the cleaning tool. The present invention provides a method and apparatus for enabling continuous recirculation of fluid to the cleaning tool at a flow rate of between about 7 and 12 gallons per minute while lowering the temperature to about 60° F.

Abstract: Installation kit for hollow rods of a pipe string, in particular a drill string, with a first end and a second end, which are connected to one another by at least one connecting line. One of the two ends is arranged in a pin of the hollow rod, and the other end is arranged in a box of the hollow rod. A seal is arranged on the first end and/or on the second end, where the first end of an installation kit that is to be connected is sealed relative to the second end, and a sealing element that seals the respective end relative to the pin or the box is arranged on the peripheral surface of each end.

Abstract: A cable splice assembly includes a tubing encapsulated cable, an electric submersible downhole cable, where the tubing encapsulated cable and the electric submersible downhole cable are tape-spliced through a pair of respective contacts, and a thermoplastic insulator to seal the tubing encapsulated cable. A shell contains the tape-spliced tubing encapsulated cable and the electric submersible downhole cable and multiple layers of sealant tape are wrapped around at least the tubing encapsulated cable and the thermoplastic insulator inside the shell, where a number of layers of the sealant tape is selected to create a pressure blocking seal inside the shell.

Abstract: A splice connector for a spoolable tube includes a center portion having an outer diameter equal to an outer diameter of the tube. A longitudinal extension extends in each longitudinal direction outwardly from the center portion. The longitudinal extensions have a plurality of spaced apart segments having an outer diameter equal to an inner diameter of the tube and a plurality of longitudinally spaced apart crimp grooves disposed between the spaced apart segments. An inner diameter of the splice connector is selected such that when the splice connector is assembled to the tube on each longitudinal extension, the splice connector is bendable to a radius of curvature of a winch reel used to deploy the tube into a wellbore.
