Abstract
ABSTRACT A novel gas separator design has been developed and successfully tested in several beam pumped wells which were subject to severe gas interference. This paper presents a detailed description of various designs to cover various ranges of fluid production for the most common sizes of completions(4-1/2 to 7 inch casing) and rates from 120 to 825 barrels of liquid per day. The new design is based on two innovations: Decentralization of the gas separator in the casing, insures that a minimum amount of gas enters the separator. The presence of two ports located on the narrow side of the annulus and placed a significant distance apart allow continuous flow of fluids into and out of the separator during both the upstroke and downstroke of the pump. These innovations have resulted in a gas separator efficiency much greater than that of conventional designs.
