The Operator of the giant ACG fields in Azerbaijan, BP, has identified significant Enhanced Oil Recovery (EOR) potential by using low salinity water injection.

Client: Az ACG
Low Salinity Seabox Study
Feasibility Study
Oct 2014 – Feb 2015
Mhrs: 5500 Mhrs
Shallow-Water Gunashli – Caspian Sea

The base case for this study is to establish the main technical data and associated cost and schedule for a 300 000 bpd plant for producing low salinity water at the Shallow-Water Gunashli (SWG) facilities utilizing the SWIT subsea technology in combination with topside microfiltration (MF) and Reverse Osmosis (RO) units. v

However, investment costs for traditional technology are too high investment compared to the potential benefit. Az ACG is therefore pursuing the low salinity EOR potential by evaluating use of the SWIT technology for supply of low salinity water to a significantly lower total investment and operation cost.
