摘要： An electric submersible pumping system includes a motor, a pump driven by the motor, and a cable that provides electrical power to the motor. The cable includes a conductor and an insulator surrounding the conductor. The insulator includes a first layer surrounding the conductor and a second layer surrounding the first layer. The insulator may include an H2S scavenger and an H2S reactant in the first or second layers surrounding the conductor. The cable optionally includes a sub-insulator layer that includes a metal or nitride coating applied directly to the conductor.

摘要： A reel assembly is provided. The reel assembly includes a housing, a drum core disposed within the housing, and a splitter flange separating the drum core into a first partition and a second partition. A first conduit is wound on the first partition of the drum core, and a second conduit is wound on the second partition of the drum core. A conduit handler system is utilized to make a connection or test a connection between the first conduit and the second conduit using actuating pistons to apply a compressive or an opposing tensile force on the connection.

摘要： The use of an environmental sensing wireline standoff may improve operations during borehole logging procedures. An environmental sensing wireline standoff may comprise a lower body, an upper body, and a cable insert. The cable insert may further comprise a first segment and a second segment, wherein the cable insert is disposed between the lower body and the upper body, and wherein the cable insert is configurable to clamp directly onto a wireline cable. The environmental sensing wireline standoff may further comprise a sensor package. A method of assembling an environmental sensing wireline standoff may comprise securing a first segment of a cable insert into a lower body, securing a second segment of the cable insert into an upper body, attaching the sensor package to the upper body, and securing the lower body to the upper body.

摘要： A fiber optic cable in the present disclosure comprises: an outer tube having an inner surface and an outer surface; a fiber in metal tube (FIMT) comprising one or more optical fibers, wherein the FIMT is disposed within the outer tube, and wherein the outer surface of the FIMT and the inner surface of the outer tube form an annular space; and a cured gelling material in the annular space. By incorporating the cured gelling material into the annular space, fluid migration through the annular space can be reduced, and sheer stress for strain coupling of the FIMT and the outer tube can be increased.

摘要： The disclosed invention concerns a method for installing and operating a thermal well (110) heat carrier transport system (100). A first flexible tubular part (120) is provided into and along a thermal well (110), a second flexible tubular part (130) is provided into the first flexible tubular part (120) and a third open ended tubular part (140) is provided into the second flexible tubular part (130). During installation and operation an installation liquid and heat carrier, respectively, is provided into the second flexible tubular part at an overpressure sufficient to press the first flexible tubular part (120) radially against the inner all of the thermal well (110) in all radial directions. The invention also concerns a system.
