DECENTRALIZED CONTINUOUS-FLOW GAS ANCHOR

A new gas separator has been developed and successfully field -tested in more than 40 beam pumped wells which were subject to severe gas int erference. The new design is based on several innovations: Decentraliz ation of the gas separator in the casing ensures that a maximum amount of liquid enters the separator. The presence of two or more ports on the gas separator near where it touches the casing wall. Construction of the gas separator so that the outer tube of the gas separator is pr essed against the casing wall to prevent cross-flow of liquid and gas. The addition of diverter at the bottom of the separator to direct mos t of the gas flow towards the wide side of the annulus. These innovati ons have resulted in a gas separator efficiency much greater than that of conventional designs.
