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.
