Abstract
With growing global energy demand and depleting reserves, enhanced oil recovery (EOR) from existing or brown fields has become more and more necessary and important. Among the various enhanced oil recovery methods, chemical EOR has drawn increasing interest from many petroleum companies. In this paper, the popular EOR methods are introduced briefly. Next, we also consider the EOR processes of chemical flooding and the screening criteria for chemical EOR processes in detail. Finally, based on the data of the White Tiger (Bach Ho) field, we evaluate and predict the potential of using chemical EOR at the main different petroleum reservoirs from the Miocene, Oligocene to fractured basement formations.
Highlights
Nowadays, with the development of the petroleum industry, enhanced oil recovery (EOR) plays an important role for almost existing oil fields
There are a lot of EOR methods
Based on the data available of the White Tiger field, we will evaluate the potential of using chemical EOR at the main petroleum reservoirs from the Miocene, Oligocene to fracture basement formations
Summary
With the development of the petroleum industry, EOR plays an important role for almost existing oil fields. EOR has become more and more necessary and effective for brown or mature field. The term EOR is oil recovery by injection of special fluids, such as gases, chemicals, thermal energy or microbial into the reservoir. Chemical flooding: alkaline, surfactant, micellar polymer, polymer, etc. Among these above methods, chemical EOR has been used from many oil companies. Chemical EOR has been used from many oil companies It has been more applicable and effective for brown/mature fields at offshore environment, such as the White Tiger field, Vietnam. Based on the data available of the White Tiger field, we will evaluate the potential of using chemical EOR at the main petroleum reservoirs from the Miocene, Oligocene to fracture basement formations
