This paper reviews the components of electrical submergible pumps with respect to field proven designs which have provided wider application in recent years. Installation procedure is described briefly to point out precautions necessary to obtain long service runs. Performance data for several oil and water supply wells are presented to show what can be expected in the way of operational and maintenance problems and expenses. And finally, the application of electrical submergible pumping is discussed with respect to economics and ultimate recovery.
The electrical submergible pump has become a common method of lifting volumes of fluid ranging up to 20,000 B/D. Pump depth may exceed 12,000 ft. Many operators who are not familiar with its varied applications are reluctant to use it because its economic success is not fully understood. The results of several applications economically proven by Marathon Oil Co. in the Big Horn Basin of Wyoming are presented herein to show that the submergible pump has its rightful place in the oil industry.
Description of Equipment
The many sizes and types of submergible pumps are too numerous to mention; but a typical installation designed to lift 4,000 bbl of fluid per day against a total head of 3,000 ft (water) is shown in Fig. 1. Components and costs for this installation are listed in Table 2.
The motor located on the bottom is a 150 hp, 3 phase, 60 cycle, squirrel cage induction type which operates at 3.600 rpm. The protector located above the motor is used to prevent well fluids from entering the motor. Its housing is bolted to both the pump and motor and contains a splined shaft that connects the pump and motor shafts to provide a direct drive.
