Enhanced oil recovery Services

ZJ designs, develops and provides chemically enhanced oil recovery (CEOR) technologies that increase the effectiveness of oil field water flooding and improves oil recovery. ZJ processes have been successfully applied in oil producing formations in China since 1998, at the most critical oil field conditions. This has resulted in additional production of 50 -120 tonnes of oil per tonne of polymer applied. For Sinopec this has resulted in more than 10 million barrels of incremental oil.

This includes product selection, reservoir evaluation, project evaluation, production and facilities design, engineering assessment, well placement and construction, plan evaluation, etc.
