Jasper disappoints

Total E&P made a minor gas discovery in well 6406/6-6S and A in the Norwegian Sea.

Total E&P drilled a side-track 6406/6-6A on the Jasper prospect after making a discovery in well 6406/6-6S (See “Jurassic discovery”) in the southern part of the Norwegian Sea. Now the NPD said in a press release it is only a minor gas discovery with preliminary estimated volumes between 0.4 and 2.5 million Sm3 of recoverable oil equivalents.

The target for the well was to prove petroleum in the Middle Jurassic Garn and Ile formation and in the Lower Jurassic Tofte formation.

Well 6406/6-6 S encountered gas in a sandstone layer of about three metres, as well as traces of gas deeper in the middle part of the Ile formation, with poor reservoir quality. The gas/water contact was not encountered. The Ile formation is about 145 metres thick, of which about 80 metres are sandstone layers. In the Garn formation, there were thin layers of tight sandstone reservoir totalling 20 metres.

The secondary exploration target in the Tofte formation was about 25 metres of aquiferous sandstone reservoir, mainly with poor reservoir quality.

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

Partners in PL 255B are Total (operator and WI 40 %), Equinor (30 %) and Petoro (30 %).
