Second plan of development approved for Thetis Island lease north of Kuparuk

The Alaska Department of Natural Resources Division of Oil and Gas has approved a second plan of development for the lease containing the 1 Thetis Island exploration well for Aug. 1, 1999, through July 31, 2000. The state certified the lease as capable of producing oil, gas or associated substances in paying quantities in 1995.
Leaseholder Anadarko Petroleum Corp. told the state that proposed work includes upgrading regional interpretations and reservoir quality predictions by integrating additional well, petrographic/core and seismic data.
The company said it also plans to integrate Fiord well data into the regional and sub-regional interpretations to tie the Fiord area with the Thetis Island area as it relates to Jurassic sand potential, conduct Brookian sequence stratigraphic and reservoir evaluations with existing seismic and well database, evaluate additional seismic purchases and evaluate future partnerships through unitization of property, either by formation of a new unit or by inclusion into an existing unit.
Adjacent to Kuukpik The offshore lease is adjacent to the northeast corner of ARCO Alaska Inc.’s Kuukpik unit, northwest of the ARCO-operated Kuparuk River unit and some 18 miles northeast of ARCO Alaska’s onshore 1 Fiord discovery well. Exxon drilled the 8,460-foot Thetis Island exploration well on the lease in 1993.
The division approved Anadarko’s second plan of development with the proviso that during the first half of 2000, and prior to submission of the next plan, the company would hold a meeting with the division director and/or his staff and present results of its evaluation of the reservoir and possible unitization efforts.
During the current plan, Aug. 1, 1998, through July 31, 1999, Anadarko said it had integrated existing and recently drilled lower Cretaceous and Jurassic well data to revise regional geologic interpretation; examined area hydrocarbon migration pathways; and evaluated the feasibility of new seismic acquisition.
