Statoil ASA, together with partners Eni Norge AS and Petoro AS, is about to complete drilling of appraisal well 7220/5-1 in the Skrugard discovery in 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.
Drilled by Transocean Barents drilling rig, appraisal well 7220/5-1 has proven a gas column of 26 meters overlaying an oil column of about 48 meters. Both column heights and reservoir properties came in as expected.
This 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,” says 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,” says 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,” Tellefsen adds.
Appraisal well 7220/5-1 is located about three kilometres north of discovery well 7220/8-1 in the Skrugard structure, and six kilometres northeast of Havis discovery. This is the third well in production licence 532, which was awarded in 2009 in connection with the 20th licensing round. The well is drilled to a vertical depth of 1740 metres below sea level at a water depth of 388 metres.
Statoil is operator for PL532 with a share of 50%. The licence partners are Eni Norge AS (30%) and Petoro AS (20%).
