Alcorn (Production) Philippines Inc. plans an extended production test on its West Linapacan A prospect off Philippines to evaluate the structure's commercial potential.
Alcorn's 1A West Linapacan well, drilled in 1,148 ft of water off Palawan Island, flowed 6,708 b/d late last year (OGJ, Dec. 24, 1990, p. 21).
Alcorn plans to reenter and complete the vertical discovery well as a subsea producer, aiming for start of production by mid-1 992, County Nat West Woodmac Far East Report said.
Two horizontal wells will then be drilled to drain the field's northeast and southern margins. All three wells will be completed and tied back to a floating production storage and offloading (FPSO) vessel. Depending on results, Alcorn could drill three to five more wells beginning in first half 1994.
Woodmac said the West Linapacan joint venture wants to use the Alcorn group's floating production riser and FPSO system stationed in Cadiao field on Philippines Permit SC6. The Cadlao and nearby Matinloc complex, also served by the unit, are scheduled to cease production in November.
The West Linapacan A extended test, expected to cost $40 million, will have an initial flow rate averaging 15,000-20,000 b/d, or four times Philippines' current production.
Woodmac said development of the West Linapacan B structure would require three more subsea wells. The future of this part of the development will depend on a wildcat to be drilled in 1993. Alcorn plans to conduct more seismic surveys of the West Linapacan B area in late 1992 or early 1993.
The Alcorn group may also include nearby Galoc oil field in a second stage development, which might boost total production to a peak of 40,000-50,000 b/d.
Partners in West Linapacan A are Alcorn 53.4%, Oriental Petroleum & Minerals Corp. 36.6%, Basic Petroleum & Minerals Inc. 7%, and Philippines Overseas Drilling Development Corp. 3%.
