Hastings, a field that once produced 75,000 barrels of oil a day, now produces less than 3,000 bbl/d, but has the potential to produce 10 times that amount with an ultimate estimated recovery of 50 million-90 million barrels under a successful CO2 injection program. This field serves as the termination point of Denbury’s Green Pipeline, and CO2 Injection As An Immiscible Application For Enhanced Recovery In Heavy Oil Reservoirs Enhanced Oil Recovery by CO2 Injection An important concept associated with the description of CO2 gas injection processes is the minimum miscibility pressure (or MMP). At this pressure, the injected gas and the initial oil in place become multi-contact miscible, and the displacement process becomes very efficient.
