..., preventing fluid from falling below the turbulent perforations to the pump intake. The concept of "Batch Pumping" is presented to industry as a simple, cost effective method to solve this separation problem for any well with this liquid holdup problem. Reservoir Surveillance controller solve downhole...

... Abstract Most well controllers require a pumping unit installation and difficult data analysis to determine and regulate for optimum well productivity.Wells with ESP's, PCP's or no pump (such as flowing wells, gas wells, etc.) require complicated and expensive equipment to accomplish the same...

... by eliminating any gas interference in the pump and controlling pump run time so the pump displacement will match the inflow of liquid from the reservoir into the wellbore. The operator must monitor well to insure that the pump has no mechanical problems and efficient operations are maintained as all...

.... With this additional information, better decisions can be made to improve the efficiency of the producing operation. Fluid level machines, dynamometers, power analyzers, and pump-off controllers have all been very successful in increasing the operation of the rod-pumped well, and to a lesser degree, the progressive...

... Abstract The gas lift injection rate and its correlation to the oil production rate has been well established. State-of-the-art electronic flow controllers are now being employed to improve the efficiency of the injection process in gas-lifted applications so that the profitability of the wells...
