North China Oilfield, 108 zone
Discovered in 1970s, North China Oilfield has been producing crude oil for almost half a century. From early 2000s on, Greatwin became a steady supplier of stabilizing and cross-linking agents for the Fifth Plant. The EOR project at 108 zone is now at its fifth cycle. By adjusting the production profile with our chemicals, the incremental crude production from 108 zone has exceeded 3,500,000 bbls.
