Abstract: 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.

Abstract: 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.

Abstract: A cable-based heater for providing underground heat and a method of assembly of the cable-based heater are provided. The heater includes a length of coiled tubing having a sealed down-hole end and an open-ended cable support adapter attached to the up-hole end of the coiled tubing. One or more conducting cables are contained within the coiled tubing and a wedging tube is placed in the open end of the adapter for supporting the weight of the one or more cables against the interior sidewall of the adapter when the heater is deployed underground. The wedging tube has an inner surface shaped to conform to the outer shape of the one or more cables and an outer sidewall configured for weight bearing frictional contact with the interior sidewall of the cable support adapter.

Abstract: A string of coiled tubing having a power cable therein supports and supplies power to an electrical submersible well pump assembly in a well. The coiled tubing has an upper section and a lower section joining each other, the upper section having a smaller inner diameter than the lower section. The power cable has an upper portion installed in the upper section of the coiled tubing and a lower portion installed in the lower section of the coiled tubing. The power cable has three insulated electrical conductors embedded within an elastomeric jacket. A metal armor strip has turns wrapped helically around the jacket. The armor strip is compressed between the jacket and the coiled tubing both in the upper section and in the lower section of the coiled tubing.

Abstract: A method of live well artificial lift completion includes hanging an umbilical on a wellhead of a live well, the umbilical fluidly coupling a production pump to a well surface and electrically coupling an electric motor to a surface power source, the electric motor powering the production pump. The umbilical includes coiled tubing surrounded by a jacket. The umbilical also includes power cables extruded inside the jacket to form a smooth jacket outer surface. The method also includes creating a pressure seal inside the umbilical during deployment of the umbilical into the live well, the pressure seal inside the umbilical created using a blowout plug positioned to block a discharge of the production pump. The method further includes forming an annular pressure seal during deployment of the production pump to obtain well control, the annular pressure seal formed using an annular bag coupled to the wellhead.

Abstract: Examples of fiber reinforced and powered coil tubing include a hollow fiber reinforced composite coiled tubing with a tubing wall having an inner surface, an outer surface and a wall thickness. The inner surface is formed to prevent absorption of fluids flowed through the coiled tubing to the tubing wall. The tubing can connect a power source at a surface of a wellbore to downhole equipment positioned within the wellbore. An electrical power conductor is embedded in the tubing wall. The conductor can transfer power from the power source to the downhole equipment. The tubing can be used to lower, install and remove downhole equipment into the wellbore without a work-over rig. The downhole equipment can be operated by transmitted power through the electrical power conductor.
