Abstract: A technique facilitates the employment of an electric submersible pumping system or other well system downhole into a wellbore. The electric motor system is coupled with a signal carrying cable for conveyance to a desired downhole location in the wellbore. The signal carrying cable is constructed with sufficient strength to solely support the electric motor system during deployment and use in the wellbore without addition of a separate supporting mechanism.

Abstract: A hydrocarbon application hose to avoid substantial compression and blow-out resulting from high pressurization differentials therethrough. The hose is formed from an inner tube that has a layer of material with electromagnetic target, such as carbon fiber, disbursed therethrough. In this manner, the material, generally a polymer, may be electromagnetically heated once the layer has been wrapped with a metallic reinforcing member. Thus, the layer of material may transform into surrounding relation relative to the reinforcing member. A substantially unitary inner tube may thereby be provided that includes a reinforcing member for blowout resistance and is of unitary character for compression resistance.

Abstract: An electrical cable having a polymeric inner layer enclosing a cable core, and a polymeric outer layer enclosing the cable core and the inner layer. The outer layer operable to maintain integrity of the cable within a predetermined temperature range.

Abstract: A heating and distributed-temperature-sensor cable permanently fixed in a wellbore that permits known amounts of heat to be introduced to subsurface formations and improved temperature measurement thereof. The heat is introduced into a target zone of the wellbore by forming the cable in two sections: an upper section that carries an electrical current without generating significant amounts of heat, and a lower section that generates heat from the electrical current. Continuous distributed-temperature-sensing is performed through measuring various scattering mechanism in optical fibers that run the length of the cable.

Abstract: Disclosed are durable corrosion resistant wellbore electrical cables including a coated electrical conductor, a polymeric protective layer for trapping coating flakes, a first insulating jacket disposed adjacent to the polymeric protective layer and having a first relative permittivity. A second insulating jacket is disposed adjacent to the first insulating jacket and has a second relative permittivity that is less than the first relative permittivity. Another aspect of the invention is a method for manufacturing a cable that includes providing a coated electrical conductor, extruding a polymeric protective layer over the coated electrical conductor, extruding a first insulating jacket over the protective polymeric layer, and extruding a second insulating jacket thereon. Cables of the invention may further include armor wire layers or even current return conductors.

Abstract: An electrical cable includes a first layer, a second layer, and a tie layer, disposed between the first layer and the second layer, for bonding the first layer to the second layer. A method of making an electrical cable includes applying a tie layer to an inner layer, the tie layer being miscible with the inner layer, and bonding an outer layer to the tie layer via one of a chemical reaction therebetween and a physical bond therebetween. An electrical cable includes a first layer, a second layer immiscible with the first layer, and a tie layer disposed between the first layer and the second layer, wherein the tie layer is miscible with the first layer and is capable of bonding with the second layer.

Abstract: A description of a cable for connection to sensors permanently downhole is provided, the cable comprising a plurality of elongate conductors capable of operative connection to sensors, a sheath surrounding the elongate conductors and holding the conductors so as to extend substantially parallel to an elongate axis, wherein the sheath has a cross-section, perpendicular to the direction of the elongate axis, which has a major dimension and a minor dimension. The cross-section of the cable is thus flattened and can be in the shape of an ellipse, a crescent or comprise a circle with wing-like portions attached on opposite sides of the circle. The sheath is made from a resilient material, so as to provide a robust outer surface of the cable which ensures the cable can be placed downhole without breaking. A number of the elongate conductors are grouped together and inter-weaved in a helical arrangement, so as to reduce electrical cross-talk between the conductors.

Abstract: Sensors are permanently placed in the ground near observation and injection wells in order to passively and continuously monitor the status of seawater advance toward fresh water aquifers near coastal cities as well as the status of fresh water injected into the injection wells. Such sensor devices are installed in the ground and electrically connected to surface acquisition equipment that would, without human intervention, transmit acquired data to a centralized facility for processing and interpretation. Various types of sensors can be used: the sensors used for general reservoir monitoring and/or the sensors used for leak detection, soil heating, and temperature mapping. Alternatively, a special type of sensor can be designed and provided for the purpose of monitoring the status of seawater advance toward fresh water aquifers.

Abstract: A cable for data transmission comprising a core comprising at least one energy transmission line; a jacket enclosing the core; armor strands wound around the jacket; and an embedding elastic structure, surrounding the jacket and designed to receive the armor strands. The cable may be manufactured as follows: (1) surrounding the core with a jacket; (2) surrounding the jacket with an embedding layer of curable but non cured thermosetting material; (3) enclosing the thermosetting layer with helically wound armor strands, in such a way that complementary grooves are generated in the embedding layer; and (4) subjecting the cable to heat in order to cure the thermosetting material of the embedding structure.
