ABSTRACT
A new gas separator has been developed and successfully field tested in more than 40 beam pumped wells which were subject to severe gas interference. The new design is based on several innovations:
{SYMBOL 183 \f "Symbol" \s 10 \h} Decentralization of the gas separator in the casing, insures that a maximum amount of liquid enters the separator. {SYMBOL 183 \f "Symbol" \s 10 \h} The presence of two or more ports on the gas separator near where it touches the casing wall. {SYMBOL 183 \f "Symbol" \s 10 \h} Construction of the gas separator so that the outer tube of the gas separator is pressed against the casing wall to prevent cross-flow of liquid and gas. {SYMBOL 183 \f "Symbol" \s 10 \h} The addition of a diverter at the bottom of the separator to direct most of the gas flow towards the wide side of the annulus.
These innovations have resulted in a gas separator efficiency much greater than that of conventional designs.
