Abstract: To develop a flow control system for use in a well, a multi-level approach is used, where the multi-level approach includes setting goals for the flow control system. According to the goals set, an overall design of the flow control system is specified, and based on the specified overall design for the flow control system, operation of the flow control system is simulated.

Abstract: A technique is provided for pumping fluids in a subterranean wellbore. A submersible pumping system can be deployed in a wellbore for moving desired fluids within the wellbore. The pumping system energizes the desired fluid movement by reciprocating a working fluid between expandable members.

Abstract: A submersible pumping system comprises a piston that is axially moveable relative to a body between an extended position and a retracted position. A pump valve is coupled to the body and in fluid communication with a supply of operating fluid. The pump valve has a first position, where the pump valve supplies operating fluid so as to move the piston to the extended position, and a second position, where the pump valve supplies operating fluid so as to move the piston to the retracted position. The pumping system also comprises an upper stop that is coupled to the pump valve so that the pump valve is moved to the first position when the upper stop is engaged by the piston in the retracted position. The pumping system also comprises a lower stop that is coupled to the pump valve so that the pump valve is moved to the second position when the lower stop is engaged by the piston in the extended position.

Abstract: A technique is provided for processing well fluid downhole. The technique utilizes equipment for separating a well fluid downhole into a water component and an oil component. The separation of water and oil can be controlled by selecting an appropriately sized flow restrictor for use in limiting the flow of one or both of the water and the oil. Additionally, a sensor system is used to monitor a well characteristic that enables adjustment of the downhole fluid processing based on well characteristic data from the sensor system.

Abstract: Configurations for gas well dewatering systems having overpressure protection to protect a pump and its peripheral equipment from damage due to overpressure are provided.
