Talisman Energy Norge has drilled dry at its wildcat well 15/12-24 S at production license 672 in the Norwegian North Sea.

The well was drilled to a measured depth of 10,305 feet below sea level in the central part of the North Sea, about 3.7 miles north of the Varg field, the Norwegian Petroleum Directorate reported Wednesday.

Well 15/12-24 S was drilled in water depths of 282 feet and was terminated in the Skagerrak formation in the Upper Triassic.

The purpose of the well was to prove petroleum in Upper Jurassic reservoir rock in the Ula and Sandnes formations and in Middle Jurassic reservoir rocks, within the Hugin and Sleipner formations.

The well encountered about 639 feet of sandstone mixed with siltstone in the Ula formation, with 508 feet of  “good to very good” quality sandstone.

Well 15/12-24 S also encountered 278 feet of sandstone mixed with siltstone in the Skagerrak formation in Upper Triassic, with 147 feet being sandstone of “generally poor reservoir quality.”

The well also found “weak” traces of petroleum in sandstone rocks in both the Ula and Skagerrak formations.

Data acquisition and sampling have been carried out.

The well has been classified as dry and has been permanently plugged and abandoned.

This is the first exploration well in the Talisman operated production licence 672.

Well 15/12-24 S was drilled by the Maersk Giant drilling facility.

The Maersk Giant will now start the permanent plugging of wells at the Varg field in production licence 038 in the North Sea, where Calgary-based Talisman Energy is the operator.
