A group led by OMV (Norge) AS discovered a 40-m gross natural gas column in the Jurassic Rogn and Garn formations at its Chamonix prospect in PL 471 in the southern Norwegian Sea off Norway.
The 6407/5-2S exploratory well went to 3,359 ft true vertical depth in 230 m of water. The well objectives were to prove hydrocarbons in the Chamonix prospect, a stratigraphic trap in the Upper Cretaceous Lysing formation and in Cortina, a secondary target in the Jurassic. The Lysing sands were found to be tight.
The well was not formation tested, but extensive data acquisition including coring and sampling have been carried out to enable a detailed evaluation as next step. The well will be plugged and abandoned.
OMV operates PL 471 with 50% interest. Noreco ASA AS has 30% and Sagex Petroleum ASA, now a member of Valiant Petroleum PLC, has 20%.
The well is the first off Norway for OMV (Norge), which has interests in nine Barents Sea licenses, two Norwegian Sea licenses, and one North Sea license. It operates seven of the licenses.
