ESPs for high GOR wells
Once bottom hole flowing pressure drops below the bubble point, significant free gas evolves out of solution. Highly efficient ESPs may suddenly substantially suffer from the free gas at intake. Therefore, special care needs to be taken on a gas-tolerating design. The industry currently offers solutions for up to 70% GVF; but not every technology is possible/necessary for every well.
How we can support you:
There are several approaches to adapt ESP designs to gassy fluids. The application of flow diverting pods, adapting pump setting depths, but of course also numerous special parts (gas separators, booster stages), may help to qualify your ESP system for gassy wells. Our team is supporting you in analyzing the impact severity of free gas on the ESPs over time and recommends the best economic technology for your application.
