AGH

Advanced gas-handling device

Increase production in wells with up to 45% GVF

Improve the overall lift efficiency of a submersible lift installation with the AGH advanced gas-handling device, which maintains a higher gas/liquid ratio (GLR) in the tubing string. It is suitable for high-GOR, gassy wells with up to 45% gas volume fraction (GVF) at low intake pressures.

The system’s higher GVF reduces the hydraulic horsepower required to lift fluid to surface. The AGH device uses a unique centrifugal stage design to alter the pressure distribution of the impeller, creating a homogenized mixture with reduced gas bubble size. This conditioned fluid behaves as a single-phase fluid before entering the pump.

Production doubled

In Kuwait, a well consistently gas locked after 60 to 70 min of operation using a REDA systems pump with a rotary gas separator. An AGH device was added to the equipment string above the gas separator with no other equipment changes. Production increased to 2,100 from 900 bbl/d with no cycling because of gas lock.

New lift alternative

A well in Mexico was producing 4,774 bbl/d (258 ft3/bbl GOR at stock-tank conditions) with gas lift using 1 MMcf/d of gas. An ESP with an AGH device was installed below a packer with fluids having 29% GVF. Production increased to 9,409 bbl/d of oil—at 363 ft3/bbl GOR at stock-tank conditions—with no gas locking.
