Abstract
A method for monitoring movement of a fluid interface in a composite reservoir includes receiving data related to a composite reservoir. The composite reservoir includes an uninvaded oil zone, a water-invaded transition zone, and an aquifer. A model is generated using the data. The model is updated in response to movement of a fluid interface between the water-invaded transition zone and the uninvaded oil zone in the composite reservoir is identified. The model is also updated in response to movement of water from the aquifer toward the wellbore is also identified, before the fluid interface reaches a wellbore formed in the composite reservoir. A remedial action is determined to take in the wellbore in response to the movement of the fluid interface, the movement of the water, or both.
