Debate over Langlitinden Discovery's Commercial Potential

Partners in the Langlitinden prospect on production license 659 in the Barents Sea, offshore Norway, are debating the economic viability of an oil reservoir that has been discovered.

Det norske oljeselskap is about to complete drilling operations on exploration well 7222/12-2, which was targeting hydrocarbons in the Kobbe Formation reservoir. After oil shows in the well were reported on February 10, the company confirmed that an oil-bearing channel sand of Triassic age exists in the well.

Rocksource Exploration Norway, a partner in the license with a five-percent interest, said that it is not yet possible to determine if the oil is economically recoverable. Det norske said that after extensive sampling, movable hydrocarbons were proved in the main target for the well but a mini drill stem test (DST) proved poor reservoir properties, and the firm added that it is of the opinion that volumes proven in the well are insufficient to justify a field development.

The well was drilled to a total depth of 9,440 feet below sea level in a water depth of 1,110 feet. It will now be permanently plugged and abandoned, Det norske said.

Det norkse, the operator of PL659, holds a 20-percent stake in the license. Other partners include Lundin Petroleum (20%), Tullow Oil (15%), Petoro (30%) and Atlantic Petroleum (10%).
