A device and method can detect, and also break, an occurrence of gas lock in an electrical submersible pump assembly in a well bore based upon surface or downhole data without the need for operator intervention. To detect an occurrence of gas lock, an instantaneous value is monitored using a sensor. Then a controller compares the instantaneous value to a threshold value over a predetermined duration to thereby detect the occurrence of gas lock in the electrical submersible pump assembly. Sensors can include, for example, a differential pressure gauge, a pressure gage located in a pump stage located toward the inlet, a fluid temperature sensor located toward the discharge, a free gas detector located near the pump discharge, an electrical resistivity gage, a flow meter located within surface production tubing, and a vibration sensor attached to a tubing string to measure a vibration signature.

Device and method for gas lock detection in an electrical submersible pump assembly

A device, method, and program product detect and break an occurrence of gas lock in an electrical submersible pump assembly in a well bore based upon surface or downhole data without the need for operator intervention. The system provides the ability to flush the pump and return the system back to production without requiring system shutdown. In addition, the system provides an algorithm for controlling a pump operating speed of the electrical submersible pump assembly to maximize production from the well bore.

A remote instrument control and reporting system utilizes a host communication gateway based on hardware and software that interfaces with a field device, remote terminal unit, or control system that operates across multiple communications infrastructures to a common back end data delivery system. This design allows Modbus hosts or similar SCADA polled technologies, such as a field bus that utilizes various industrial protocols to control instruments at and acquire instrumentation data from physically isolated installations. In particular, this design is well suited for applications such as oil well electrical submersible pumps. The data is communicated through, for example, a low Earth orbit satellite into a host communications gateway that simulates within a host computer environment the same polling registers that the data was collected from in the remote locations.
