Abstract: A system may include a controller couplable to an imaging sub-system utilizing multiple particle beams, where the imaging sub-system includes one or more control elements to manipulate the two or more particle beams that are adjustable with two or more control parameters. The controller may select values of the two or more control parameters by iteratively performing steps until one or more termination conditions are met. For example, the controller may receive measurements of changes of distortions of the particle beams resulting from individual adjustments of the control parameters. The controller may further calculate values of the control parameters that reduce the distortions of the particle beams based on the changes of the distortions resulting from the individual adjustments. The controller may further direct the adjustment of the values of the control parameters to the calculated values.

Abstract: Gas lock resolution during operation of an electric submersible pump is provided. An example method, module, or computing hardware with software product, detects a gas lock during current operation of an electric submersible pump (ESP) and intervenes to relieve the gas lock without stopping the ESP. After sensing a gas lock condition, an example module calculates a pump speed for attempting gas lock resolution. The example module may decrease the speed of the ESP to flush the gas lock, and then reaccelerate the ESP to check that the gas lock has been eliminated. The example module may apply one or more stored motor speed patterns that iteratively seek a pump speed that succeeds in clearing the gas lock, without stopping the ESP. The example module has built-in protections to protect the ESP from thermal overload and other damage.

Abstract: A dual barrier side pocket mandrel with gauge includes a gas lift barrier valve mandrel with permanent sensors and at least two pockets for accepting gas lift barrier valves, wherein the pockets are connected via a port. The mandrel also includes a production conduit along a central longitudinal axis. The mandrel is encompassed by a casing on the inside of a well. The permanent sensors can monitor a pressure or a temperature in the casing, production conduit, and port to determine the status of the individual gas lift barrier valves.

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.
