OSTI ID:6412339
The pilot is a contained 40-acre 5-spot located in a representative watered-out portion of the Unit A Reservoir. The pay is sandstone with an average net pay of 6.4 feet, air permeability of 1050 md, and water TDS of 2500 ppM. The average remaining oil saturation in the 40-acre pilot area was estimated to be 28% at the start of chemical injection. The Pilot has four injectors (Wells MPP-1, MPP-2, MPP-3, and MPP-4) and one producer (Well 12-1). The overall micellar-polymer oil recovery is estimated at 47% of the remaining oil at the initiation of the micellar-polymer flood. In the fourth contract year, micellar slug injection was completed and injection of the graded mobility buffer began. A second radioactive/chemical tracer test was begun at the start of the polymer phase. A delay of approximately one year was experienced during the reservoir description phase. Otherwise, the project has remained on schedule.
