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
Project:
Low Salinity Seabox Study
Scope:
Feasibility Study
Date:
Oct 2014 – Feb 2015
Mhrs: 5500 Mhrs
Location:
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.

Scope of Work:

The Scope of Work for this study was to develop Appraise Quality study deliverable

  • Basis of design for complete project
  • Technology evaluation report
  • Class V engineering package
    • PFD and draft P&Ids
    • MEL and utility load list
    • Operability
    • GA and layout drawings
  • Class V cost estimates
    • Class V cost estimate
    • Level 1 schedule
    • WBS
    • Risk matrix

The study concluded the technical, project schedule and cost feasibility of the SWIT technology. Furthermore, developed basis for FEED work.
