The PUT River, appraisal and development of a minor reservoir within the Prudhoe Bay Field, North Slope, Alaska

摘要

PUT River formation is an early Cretaceous reservoir in the North Slope, Alaska. Stratigraphically it lies above the Lower Cretaceous Unconformity (LCU) and below the Highly Radioactive Zone (HRZ). The reservoir sands are near shore face to shallow marine deposits with heavy bio-turbation. In the Prudhoe Bay Field the PUT River reservoir overlays the Sadlerochit interval, the main producing horizon. A number of the Prudhoe Bay development wells penetrate the PUT River reservoir and provide well control for defining the areal extent and thickness of the reservoir.
