Abstract: A modular cable unit for oilfield wireline includes multiple cable modules. The cable modules are interchangeable to achieve a modular cable unit with desired telemetry and electrical properties to suit a specific application. The cable modules can be an optical fiber module, a power cable or an opto-electrical module assembly. The cable modules that make up the modular cable unit are preferably arranged in a triad configuration defining a substantially triangular tangent periphery and are surrounded by a polymeric casing having a circular periphery. The triad configuration of the modular cable unit contributes to an improved mechanical strength. A floating-tube type optical fiber element with improved mechanical strength is also disclosed.

Abstract: A cable for supplying power to an electric submersible pump (ESP) includes a helically disposed electrical conductor, at least one polymer layer extruded to embed the helically disposed electrical conductor, and a seam-welded metallic tube drawn over the hard polymer layer, all providing resistance to corrosive chemicals at high downhole pressures and temperatures. In an implementation, the helical disposition of cable components, added cushioning polymers and geometry, and a non-leaded metallic tube compensate for stress and differential thermal expansion to keep the cable protected from intrusion of corrosive chemicals. An example method of manufacture includes extruding a polymer layer to embed the helically disposed electrical conductor, seam-welding a metal strip to form a metallic tube around the polymer layer, and drawing the metallic tube down to fit tightly around the polymer layer.

Abstract: Devices, systems and methods for equalizing pressure in a gas well are provided. A jar device is coupled to a pump deployed in a gas well between areas of low pressure and high pressure. The jar device includes a mandrel and a no-go sleeve. A jarring tool is operated to transfer an axial force onto the jar device that is large enough to shear a shearable connection between the mandrel and no-go sleeve and thereby cause the mandrel to slide from a first position to a second position with respect to the no-go sleeve. A seal that seals between the no-go sleeve and mandrel when the mandrel is located in the first position is unsealed as a result of the movement of the mandrel and thereby fluid communication is allowed between the area of high pressure and low pressure. This allows for easier retrieval of the pump.

Abstract: A hydrocarbon monitoring cable including resistance to development of defects in a fiber optic core thereof. The core defect resistance may be in the form of resistance to defect causing agents of a downhole environment such as hydrogen. This may be obtained through the use of a carbon layer about the fiber optic core. However, in light of the differing coefficients of thermal expansion between such a carbon layer and an outer polymer jacket, an intermediate polymer layer of a third coefficient of thermal expansion may be disposed between the carbon and jacket layers. Thus, the intermediate polymer layer may be of a third coefficient of thermal expansion selected so as to avoid fiber optic defect causing thermal expansion from the downhole environment itself. Additionally, the monitoring cable may include an electrically conductive layer about the fiber optic core that is positively charged to repel other positively charged fiber optic defect causing agents of the downhole environment. Furthermore, a polymer-based absorbing layer for absorbing such defect causing agents may be disposed about the fiber optic core for protection.

Abstract: A motor winding wire. The motor winding wire may be configured for use in, and direct exposure to, a hydrocarbon environment. The motor winding wire may be electrically insulated by one polymer layer, whereas another, outer, polymer layer is employed to provide moisture resistance as well as other contaminant and hydrocarbon environment shielding to the underlying layer. Additionally, this manner of polymer layering over the motor winding wire is achieved in a manner cognizant of the limited dimension of the motor winding wire.

Abstract: Electrical cables formed from at least one insulated conductor, a layer of inner armor wires disposed adjacent the insulated conductor, and a layer of shaped strength members disposed adjacent the outer periphery of the first layer of armor wires. A polymeric material is disposed in interstitial spaces formed between the inner armor wires and the layer of shaped strength members, and the polymeric material is further disposed in interstitial spaces formed between the inner armor wire layer and insulated conductor. The polymeric material serves as a continuously bonded layer which also separates and encapsulates the armor wires forming the inner armor wire layer wire layer.
