Zelin provides natural gas compression and reinjection equipment and professional O&M services to improve recovery and reduce emissions.
Key principles & suitable reservoirs
Nitrogen foam flooding technology can reduce water cut and enhance oil recovery by increasing swept volume. Foam dynamically blocks high water-cut pores, expands swept volume, and realizes water control and productivity increase.
After recovery and pressurization, natural gas can be reinjected by single-well huff-and-puff or well-group gas flooding to replenish formation energy and improve oil displacement efficiency.
Field-proven performance improvement
In the late stage of waterflood development, injected water burst unidirectionally along large pores, resulting in high water cut. After implementing three-phase compound flooding (solid phase + gas phase + liquid phase), the well group injection effect improved. Comprehensive water cut reduced to 69.5%, daily oil increase reached 12–18t, and cumulative oil increased by 2449t.
