The Rumaila field is located in South East Iraq and contains multiple reservoir intervals,
including the Upper Cretaceous Mishrif carbonate. This reservoir has been on production for
many years but still contains significant oil reserves. Reservoir pressure has dropped due to
historical production and, therefore, large scale water injection is planned to support future
production. Full field models have been built in order to simulate the planned Mishrif water
injection. These models were calibrated using available historical data, such as well …
