20090194314 | Bimetallic Wire with Highly Conductive Core in Oilfield Applications - A cable and a method of making the cable includes an electrically conductive cable core for transmitting electrical power and at least one layer of a plurality of armor wires surrounding the cable core. At least one of the armor wires is a bimetallic armor wire having a coaxial inner portion and a surrounding outer portion. The inner and outer portions are formed of different metallic materials and the bimetallic armor wire provides a return path for the electrical power transmitted through the cable core. | 08-06-2009 |
20090196557 | DUAL CONDUCTOR FIBER OPTIC CABLE - A powered fiber optic cable for use in a hydrocarbon well of extensive depth and/or deviation. The cable may couple to a downhole tool for deployment to well locations of over 30,000 feet in depth while maintaining effective surface communication and powering of the tool. The cable may be configured to optimize volume within a core thereof by employing semi-circular forward and return power conducting portions about a central fiber optic portion. As such, the cable may maintain a lightweight character and a low profile of less than about 0.5 inches in diameter in spite of powering requirements for the downhole tool or the extensive length of the cable itself. | 08-06-2009 |
20090283295 | TORQUE-BALANCED ELECTRICAL CABLE - An embodiment of a wellbore cable comprises a cable core, at least a first armor wire layer comprising a plurality of strength members and surrounding the cable core, and at least a second armor wire layer comprising a plurality of strength members surrounding the first armor wire layer, the second armor wire layer covering a predetermined percentage of the circumference of the first armor wire layer to prevent torque imbalance in the cable. | 11-19-2009 |
20120097419 | Wireline Cables Not Requiring Seasoning - A cable includes an electrically conductive cable core for transmitting electrical power and data, an insulative/protective layer circumferentially disposed around the core, an inner armor wire layer including a plurality of armor wires disposed around the cable core and the insulative layer, wherein at least one of the armor wires of the inner armor wire layer is bonded to the insulative layer, and an outer armor wire layer including a plurality of armor wires disposed around the inner armor wire layer. At least one of the armor wires of the outer armor wire layer can be bonded to the at least one of the armor wires of the inner armor wire layer. | 04-26-2012 |
20130202259 | COAXIAL CABLES WITH SHAPED METALLIC CONDUCTORS - The present invention provides a coaxial cable which comprises a cable core encased in a polymeric layer, enclosing the cable core with a pair of shaped conductors; extruding a layer of polymer over the shaped conductors; and cabling armor wire layer about the layer of polymer to form the coaxial cable. | 08-08-2013 |
20130227837 | CABLE COMPONENTS AND METHODS OF MAKING AND USING SAME - An embodiment of a method for manufacturing a cable component comprises providing at least a pair of shaped wire members, passing the wire members through at least one shaped roller set, providing at least one cable portion, placing the wire members over the cable portion and running the wire members and cable portion through an assembly roller to form a cable subassembly, and attaching a fixing element to the cable subassembly to secure the wire members and cable portion to complete the cable component. | 09-05-2013 |
20150037581 | CABLE HAVING STRENGTH MEMBER WITH BONDED POLYMER COATINGS TO CREATE CONTINUOUSLY BONDED JACKETED STRENGTH MEMBER SYSTEM - The present disclosure comprises providing a cable core encased in a polymeric layer, cabling a first armor wire layer about the cable core, cabling a second armor wire layer about the first armor wire layer to form the cable, each of the armor wire layers comprising a plurality of strength members, at least one of the armor wire layers comprising a plurality of strength members having a polymeric layer bonded thereto. | 02-05-2015 |
20150047858 | Methods And Systems For Deploying Cable Into A Well - A system for deploying cable that includes a housing. The housing is configured to receive circulating lubricant, and a drive assembly is located within the housing. The drive assembly includes a first gripper portion and a second gripper portion. The grips portions are supported by independent frames. An actuator is connected with one of the frames. The actuator provides force that causes the gripper portions to engage and cooperate to support and deploy cable. | 02-19-2015 |
20150075696 | Wireline Cables Not Requiring Seasoning - A cable includes an electrically conductive cable core for transmitting electrical power and data, an insulative/protective layer circumferentially disposed around the core, an inner armor wire layer including a plurality of armor wires disposed around the cable core and the insulative layer, wherein at least one of the armor wires of the inner armor wire layer is bonded to the insulative layer, and an outer armor wire layer including a plurality of armor wires disposed around the inner armor wire layer. At least one of the armor wires of the outer armor wire layer can be bonded to the at least one of the armor wires of the inner armor wire layer. | 03-19-2015 |
