Wintershall is to begin evaluating development options for the Skarfjell discovery, after a second appraisal well on the field exceeded expectations.
Options could includea tie back to the Gjøa platform, or another facility, or as a standalone development.The German operator said the Skarfjell Southwell, consisting a main bore (35/9-10S) and a sidetrack (35/9-10A), confirmedoil volumes and additional gas, putting a preliminary resource estimate at 120–230MM boe.
Oil and gas was provied in the upper and lower Intra-Heather sandstones of the Skarfjell structure, with reservoir properties exceeding expectations.Drilling was carried out using the semisubmersible rig Transocean Arctic.
Skarfjell was discovered by Wintershall in 2012, is about 15km southwest of the Gjøa platform, and about 130km northwest of Bergen.A first appraisal well in the northern part of Skarfjell proved an extension of the field to the north, and suggested 60-160MM boe resources.
Wintershall says Skarfjell South has proved an extension of the structure to the south, and reduced uncertainties in the reservoir quality distribution.
“Wintershall will now start evaluating Skarfjell for development together with other discoveries in the area, potentially as a tie back to the Gjøa platform or other facility, or as a standalone development,"says Bernd Schrimpf, managing director of Wintershall Norge AS..
The main bore 35/9-10S was drilled to a vertical depth of 2837m below sea level and terminated in the Brent Group. The sidetrack 35/9-10A was drilled to a vertical depth of 2835m below sea level and also terminated in the Brent Group.
