Sidetrack hikes Osprey to top Cook Inlet platform

Miller Energy Resources Inc., Huntsville, Tenn., said its Cook Inlet Energy unit is producing its RU-1A sidetrack well in Alaska at a reduced rate while it conducts formation analysis after having brought the wellbore online on Aug. 17 at more than 700 b/d of oil at 5% water cut.

The subsidiary will adjust pump speed and increase production accordingly in order to preserve reservoir integrity and maintain optimal reservoir pressure.

The companies said the sidetrack, which encountered oil throughout the Hemlock formation and in the top of the West Foreland formation, produced at more than twice the historical IP rate. The sidetrack has 455 gross ft of perforations. TD is 15,050 ft measured total depth.

Oil production from the Osprey platform has averaged 2,180 b/d and including gas more than 2,500 b/d of oil equivalent. With the addition of the RU-1A output, the companies estimated that Osprey is now the single highest producing oil platform in Cook Inlet. The rig will now sidetrack the RU-5 well.
