Differential gas pump

Differential gas pump

Differential gas pump is used for production of high GOR crude to reduce or eliminate negative impact of gas on downhole equipment.

Application

Production of fluid with high GOR: up to
60% of free gas on pump intake.

Advantages

Top travelling valve creates low-pressure chamber under
bottom standing valve by shutting off hydrostatic fluid column;
User-friendly design and installation;
Steady performance at high GOR;

Benefits

Well treatment reduction;
Prevention of downhole equipment premature failure;
Prevention of gas lock;
Higher pump efficiency in comparison with conventional SRP;
