Lundin Petroleum spuds Nemo appraisal well, offshore norway

Lundin Petroleum, through its wholly owned subsidiary Lundin Norway AS (Lundin Norway), is pleased to announce the flow test rate of the previously announced Gohta discovery of approximately 4,300 barrels of oil per day (bopd). Gohta is Lundin Petroleum's first oil discovery in the Barents Sea, offshore Norway.

The well 7120/1-3 operated by Lundin Petroleum was drilled on PL492 approximately 35 kilometres north of the Snøhvit field in the Barents Sea. The well proved oil in contact with an overlying gas cap.

The purpose of the well was to prove petroleum in reservoir rocks in Triassic sandstone reservoirs and Permo-Carboniferous carbonate reservoir. In the carbonate reservoir the well found a 25 metres gross gas column above a 75 metres gross oil column in karstified and dolomitized limestone. The Triassic sandstone was water bearing.

A production test (DST) was performed to assess the quality of the carbonate reservoir. The DST produced a flow rate of approximately 4,300 bopd through a 44/64" choke with a gas oil ratio of 1,040 standard cubic feet per barrel. The main flow of the reservoir was stable over 24 hours and the pressure buildup lasted 36 hours and did not show any barriers such as faults or significant reservoir characteristics variations. This is the first successful test of Permian carbonates reservoirs on the Norwegian shelf.
