Overcoming Deep Water Challenges For Enhanced Oil Recovery

Maximizing oil recovery in offshore fields can require a myriad of enhanced oil recovery (EOR) techniques which can add complexity at subsea depths. In 2012, Petrobras was seeking to couple high pressure carbon dioxide (CO2) injection with other unconventional EOR techniques. While used extensively in onshore fields, offshore CO2 injection, especially in deep water developments, adds an extra level of complexity that had not previously been employed.
