Estimating the term…
A software implemented method that facilities operational processes through control of a variable speed drive (VSD) that electrically drives a motor of an Electrical Submersible Pump (ESP). The control system utilizes a human interface displaying drive and pump parameters that permits adjustments. Detection of a drop in motor amps indicates gas lock wherein pump stages nearest the intake are affected by gas entering the pump. Motor speed is increased for increasing head generated by stages unaffected by gas. The motor speed increase generates total head in excess of pump depth. Feet of head generated may be calculated for each of stage of the pump at a given motor speed. The feet of head per stage is multiplied by a number of stages to determine total head generated. The total head generated is compared to the pump depth, and motor speed is increased until the total head exceeds pump depth.
A method of operating an electrical submersible pump installation comprising:
A method of eliminating gas lock in an electrical submersible pump having a pump with multiple stages and a pump intake, the pump driven by a motor, said method comprising the steps of:
