The TOTAL E&P Norge operated exploration well 25/5-9 on the Trell prospect in production license 102 F/G in the Norwegian North Sea has discovered oil in the Paleocene Heimdal Formation.
The well intersected 19m of net pay in excellent quality Heimdal reservoir, in a location close to existing infrastructure, says Aberdeen-based partner Ithaca Energy.
Wireline logs and pressure data have confirmed a hydrocarbon contact and samples of oil and water were acquired for further analysis.
Total's preliminary estimate for recoverable oil in Trell is 3.1-12.5MM bbl.
This is the first exploration well in production licence 102 F. The licence, which was recently carved out of another production license, 102 D, was awarded on 10 October 2013.Ithaca entered into an agreement with TOTAL in December 2013, to acquire a 10% working interest in license PL102 F/G.
Completion of the transaction is currently progressing through the normal regulatory consents. The agreement is consistent with Ithaca’s strategy in Norway of gaining access to lower risk exploration opportunities capable of monetization prior to development.
The PL102 F/G licensees are TOTAL 40%, (operator), Petoro 30%, Lotos Exploration and Production Norge 10%, Det Norske Oljeselskap 10% and Ithaca 10%.
The well was drilled to 2240m true vertical depth subsea and encountered a 21m gross oil column. The discovery was made in a mature area of the Norwegian North Sea, about 10km from the Heimdal production hub.
Well 25/5-9 was drilled by the Leiv Eiriksson semisubmersible drilling rig, which will now proceed to production license 420 in the northern North Sea to drill appraisal well 35/9-11 S, where RWE Dea Norge AS is the operator.
