Abstract: A system for controlling fluid flow in a subterranean well includes a first valve, a control line fluidly coupled to the first valve, an equalizing line disposed externally to and separate from the first valve, and at least a second valve disposed in the equalizing line and in fluid communication with the control line. The first valve includes a body defining a lumen, and an upper portion, and a lower portion. The equalizing line is in fluid communication with the lumen between the upper portion and the lower portion of the body. The second valve equalizes a pressure between the upper and lower portions of the body.

Abstract: The disclosed embodiments include a method to protect a downhole generator from overvoltage. In one embodiment, the method includes determining a speed of an alternator. The method also includes activating overvoltage protection mode if the speed of the alternator is greater than a threshold speed, where activating the overvoltage protection mode includes converting an alternating current measured at the alternator into a first component and a second component of a direct current. Activating the overvoltage protection mode also includes determining a first current threshold based on at least one component of the downhole generator. Activating the overvoltage protection mode also includes shutting down the downhole generator if the first component of the direct current is greater than the first current threshold and decreasing a magnetic flux of the downhole generator if the first component of the direct current is not greater than the first current threshold.

Abstract: The present disclosure relates to oil and gas exploration and production, and more particularly to systems and methods for evaluating sand-resistivity and/or sand-conductivity, as well as saturation in laminated shale-sand formations with biaxial anisotropy. Shale is one of the more important common constituents of rocks in log analysis. Aside from their effects on porosity and permeability, their importance stems from their electrical properties, which have a great influence on the determination of fluid saturations. Shale can exist in the form of laminae between which are layers of sand. Laminae are small scale sequence of fine layers that occurs in sedimentary rocks.

Abstract: A bend stiffener is operable to be installed on site in a collapsed state and expanded upon installation to provide increased coverage of a tubing string to be reinforced by the bend stiffener. The bend stiffener is expandable upon the tripping of tubing through the bend stiffener. The bend stiffener includes a flexible sleeve having an outer flange at an upper end and sized to receive the tubing. The bend stiffener also includes an intermediary sleeve and an external sleeve. The intermediary sleeve has a cylindrical body and an internal flange for engaging and supporting the outer flange of the flexible sleeve. Similarly, the external sleeve has an internal flange for supporting an external flange of the intermediary sleeve. When installed, the flexible sleeve slides from the intermediary sleeve and the intermediary sleeve slides from the external sleeve so that each sleeve encloses and reinforces a segment of tubing.
