Abstract: Sensors for imaging boreholes via the detection of electrical and optical properties may be subject to harsh conditions downhole, such as from pressure and temperature. In addition, these sensors may be subject to impact, such as tension, elongation, and compression forces, along the wall of the borehole. The harsh conditions downhole and impacts on the sensor can lead to premature wear and even breaking. The present disclosure generally relates to an apparatus for measuring electrical and optical properties of the borehole and methods for manufacturing the apparatus.

Abstract: Representative implementations of devices and techniques provide a system arranged to deploy and retrieve a device such as an electric submersible pump with respect to a well or other like formation. An injection device for coiled tubing is modified to grip and inject a cable in order to lower a pump or like device into a wellbore. Modification to the tube injection device may include addition of cable-gripping blocks to the injection components. Multiple injection devices can be utilized to open and close in coordination in order to let a large connector or termination on the cable pass through an open injector while a closed injector maintains a grip on the cable.

Abstract: A system includes a cable and a toolstring. The toolstring may couple to the cable to enable the toolstring to be placed in a wellbore. The toolstring includes a sensor that can collect measurements relating to the wellbore. An electromagnetic or anchoring device may selectively hold the toolstring or the cable against a surface of the wellbore.

Abstract: Cable termination assemblies and processes for making and using same. In some examples, the cable termination assembly can include a lower housing and a rope socket housing can be disposed at least partially within a lower housing bore defined by a lower housing inner surface. At least one rope socket retainer can be disposed at least partially within a rope socket bore defined by an inner surface of the rope socket housing. The rope socket housing and rope socket retainer can be configured to secure the rope socket housing to a first set of armor wires of a cable, extending at least partially through the rope socket bore, while leaving interstitial gaps between individual armor wires of the first set of armor wires. A filler can be disposed between the individual armor wires of the first set of armor wires that at least partially fills the interstitial gaps.

Abstract: A small-diameter, continuously bonded cable and a method for manufacturing the same includes at least one longitudinally extending inner metallic component with a tie layer of an amended polymer material surrounding and bonded thereto in steps of heating and extruding. A longitudinally extending outer metallic component is radially spaced from the at least one inner metallic component and incased in a polymer material jacket layer in heating and extruding steps. The polymer materials insulate the metallic component for conducting electrical power and/or data signals.

Abstract: A downhole cable that has a cable core with an inner jacket located about it. The inner jacket has a shell located thereabout, and a pair of strength member layers surrounds the inner shell. Interstitial spaces of the strength member layers are filled with bonding layers. One of the strength member layers is at a contra-helical lay angle to the other. An outer jacket is located about one of the strength member layers, and the outer jacket is bonded with the bonding layers.

Abstract: A torque-balanced, gas-blocking wireline cable and a method of making the cable includes an electrically conductive cable core for transmitting electrical power and surrounding inner and outer layers of a plurality of armor wires. Gas blocking is achieved by placing a soft polymer layer over the core before the inner wires are cabled thereon. The inner wires imbed partially into the soft polymer layer such that no gaps are left between the inner wires and the core. A second soft polymer layer is optionally extruded over the inner wires before the outer wires are applied. The second soft polymer layer fills any spaces between the inner and outer wire layers and prevents pressurized gas from infiltrating between the wires. The inner wires have larger diameters than the outer wires such that the inner wires carry approximately 60% of the load and torque imbalance is prevented.
Abstract translation: 扭矩平衡的阻气电缆电缆和制造电缆的方法包括用于传输电力并围绕多个铠装线的内层和外层的导电电缆芯。 气体阻塞是通过将软聚合物层置于芯上而实现的，然后将内部电线连接在芯上。 内部线材部分地嵌入软质聚合物层中，使得内部线材和芯部之间没有间隙。 在施加外部电线之前，第二软聚合物层任选地在内部电线上挤出。 第二软聚合物层填充内部和外部线层之间的任何空间，并且防止加压气体渗入电线之间。 内部线材的直径大于外部线材，因此内部线材承载大约60％的负载，并且防止扭矩不平衡。
