MGH Multiphase Gas-Handling System

Increased production and reservoir life in gassy wells

High-GOR, high-gas environments are now common ESP applications, but in order to produce at full potential, main production pumps need the support of reliable gas-handling technology. The MGH gas-handling system is designed to manage this issue, along with liquid-loading problems in gas wells. The specially designed axial-flow stages of the MGH gas-handling system provide a more efficient energy transfer than centrifugal stages, avoiding gas locking at high gas-volume fractions (GVF). The system efficiently manages higher percentages of free gas in gassy wells and achieves much higher drawdowns in subsea wells and wells with non-vented packers, resulting in trouble-free operations and increased production from reservoirs.

Efficiently handles up to 75% free gas

Standard gas-handling systems rely on centrifugal force to transfer energy to the liquid or gas mixture. Even with a free gas content of 10 to 20% in the pump, the liquid and gas will separate, and energy transfer efficiency will decrease. If enough gas accumulates, the pump will gas lock and prevent fluid movement. The MGH system's helicon-axial flow stage ensures a good mix between the gas and liquid. It breaks up large gas bubbles, reduces the gas volume, and primes the main production pump. The system can successfully operate at lower intake pressures with GVF in the pump up to 75%, far exceeding the 40 to 45% GVF limits of conventional gas-handling devices. The field-proven system can be installed in conjunction with a gas separator or a standard intake, depending on the application.
