French oil company Total has completed drilling two wells in the Norwegian Sea, making a small gas discovery in the process.

The Norwegian Petroleum Directorate said on Friday that Total had completed the drilling of wildcard well 6406 / 6-6 S and appraisal well 6406 / 6-6 A. Kristin camp in the southern part of the country. Norwegian Sea. The main exploration target of the well was the demonstration of oil in the rocks of the Middle Jurassic reservoir (Garn and Ile formation). The well's secondary exploration target was the demonstration of oil in the rocks of the Lower Jurassic reservoir (the Tofte formation).

In the primary exploration target, well 6406 / 6-6 S found gas in a sandstone layer of about three meters, as well as traces of gas deeper in the central part of the ile formation, with poor reservoir quality. Gas / water contact not found. The Ile formation is about 145 meters thick, of which about 80 meters are sandstone layers. In the Garn formation, there were thin layers of tight sandstone reservoir totaling 20 meters.

The secondary exploration target in the Tofte formation was about 25 meters of aquifer sandstone reservoir, mostly with poor reservoir quality.

In appraisal well 6406 / 6-6 A, the Ile formation was thinner, with a total of about 55 meters of sandstone reservoir, and the quality of the reservoir rocks was confirmed. Technical problems made it impossible to carry out measurements that could confirm a gas column. In the Garn formation, there were thin layers of tight sandstone reservoir totaling 25 meters.

None of the wells have been formation tested, but extensive data acquisition and sampling has been carried out in well 6406/6-6 S, NPD said.

Preliminary estimates place the size of the discovery between 0,4 and 2,5 million standard cubic meters (Sm3) of recoverable oil equivalents.

Licensees on the 255B production license will evaluate the discovery along with other nearby discoveries and prospects for further follow-up.

These are the second and third exploration wells in production license 255 B. The license was extracted from production license 255 (granted in the 16th licensing round) on May 19, 2016.

Well 6406 / 6-6 S was drilled to the respective vertical depths and measurements of 4784 and 4877 meters below the sea surface, and well 6406 / 6-6 A was drilled to the respective vertical depths and measurements of 4659 and 4835 meters below the surface of the sea. Both ended up in the Ror formation in the Lower Jurassic.

The water depth is 265 meters. The wells were permanently connected and abandoned.

Wells 6406/6-6 S and 6406/6-6 A were drilled by the semi-submersible drilling rig Scarabeo 8, which is now drilling wildcard well 24/9-14 S in production license 869 in the central part of Mar do Norte, where Aker BP ASA is the operator.
