Equinor Energy AS, operator of manufacturing license (PL) 025, has concluded the drilling of appraisal effectively 15/Three-11 on the 15/Three-Four (Sigrun) oil and gasoline discovery.
The effectively was drilled about 10 km southeast of Gudrun subject within the North Sea, and about 225 km west of Stavanger.
The goal of the effectively was to delineate the 15/Three-Four discovery in three reservoir zones within the Middle Jurassic (the Hugin formation).
The discovery was confirmed in reservoir rocks from the Middle Jurassic within the Brent group in 1982. Before effectively 15/Three-11 was drilled, the operator’s useful resource estimate for the invention was between zero.Three MMscm and 1.Four MMscm of recoverable oil equivalents.
The effectively encountered a complete oil column of about 35 m within the Hugin formation, of which a few 15-m thick sandstone layer with poor to average reservoir high quality. The oil/water contact was not encountered. Preliminary estimates of the scale of the invention after the delineation effectively are between 1.1 MMscm and a couple of MMscm of recoverable oil equivalents.
The effectively was not formation-tested, however in depth information acquisition and sampling have been carried out.
The licensees in manufacturing licence 025 will assess the profitability of the invention with regard to a possible growth over Gudrun subject.
This is the ninth exploration effectively in PL 025. The license was awarded in licensing spherical 2-A in 1969.
Appraisal effectively 15/Three-11 was drilled to a vertical depth of three,991 m beneath the ocean floor, and was terminated within the Sleipner formation within the Middle Jurassic. Water depth on the website is 109 m. The effectively has been completely plugged and deserted.
The effectively was drilled by the Deepsea Bergen, which can now drill wildcat effectively 35/10-Four S in manufacturing license 630 within the northern a part of the North Sea, the place Equinor Energy AS is the operator.
