Screening of EOR Processes for the Kharaib B Reservoir of the Giant Al Shaheen field, Offshore Qatar

This paper describes the enhanced oil recovery (EOR) studies conducted for the low permeability Kharaib B carbonate reservoir of the Al Shaheen field, located offshore Qatar. The reservoir is characterised by large lateral variation in oil properties (Lindeloff et al., 2008), lateral uniformity in geological and petrophysical properties over large distances, a relatively thin oil column in a transition zone, and the presence of local gas caps. The Kharaib B reservoir is currently undergoing water-flooding, which is reaching maturity in parts of the field.
