Norway's Statoil announced Tuesday that it is about to complete the drilling of appraisal well 72290/5-1 in the Skrugard discovery of the Barents Sea.
The objectives of the appraisal well were to confirm the previous volume estimate for the Skrugard discovery and to collect reservoir and overburden data for field development planning. Both objectives have been met, said Statoil.
Drilled by Transocean Barents (semisub) drilling rig, appraisal well 7220/5-1 has proven a gas column of 85 feet (26 meters) overlaying an oil column of about 158 feet (48 meters). Both column heights and reservoir properties came in as expected.
This, said Statoil, confirms the previous volume estimate for the Skrugard discovery and the total resource estimate for the Skrugard and Havis structures in the range of 400-600 million barrels of recoverable oil.
"We are very satisfied with the results of the first appraisal well on Skrugard. All findings are in line with our expectations. We are now evaluating further exploration drilling in the area," said Knut Harald Nygård, vice president exploration Skrugard area.
Skrugard/Havis will be the northernmost field development on the Norwegian continental shelf so far.
"The positive result confirms the basis for a development of Skrugard and Havis. The data and fluid samples acquired from the well are very valuable in our work to establish a robust development solution for the area and our aim to develop the Barents Sea into a core area for Statoil,” added Erik Strand Tellefsen, vice president for Skrugard field development.
"We are currently considering several alternative development concepts. The reservoir engineering work is mainly done in-house while we are in the process of awarding several study contracts to engineering companies for the subsea and platform installations."
Appraisal well 7220/5-1 is located about 1.9 miles (3 kilometers) north of discovery well 7220/8-1 in the Skrugard structure, and 3.7 miles (6 kilometers) northeast of Havis discovery. This is the third well in production license 532, which was awarded in 2009 in connection with the 20th licensing round. The well is drilled to a vertical depth of 5,700 feet (1,740 meters) below sea level at a water depth of 1270 feet (388 meters).
Statoil is operator for PL532 with a share of 50 percent. The license partners are Eni Norge AS (30 percent) and Petoro AS (20 percent).
