Miscible displacement drive for enhanced oil recovery in low pressure reservoirs

Patent ·
OSTI ID:5357147

A process of utilizing natural gas to obtain a miscible drive fluid for low pressure reservoirs is described. The process involves upgrading natural gas to ethane, propane and butane constituents which are fabricated into a mixture which is miscible at the reservoir conditions. The process is operated so as to maximize the reuse of the upgraded miscible drive fluid and therefore lower the cost of enhancing the oil recovery from a low pressure reservoir.
