Equinor strikes oil near Gudrun field in North Sea
Equinor received drilling permits for the two North Sea wells in November 2019. The wells are located in production license 025 where Equinor is the operator.
The wells were drilled about 11 kilometers southeast of Gudrun, 4 kilometers southeast of the 15/3-4 (Sigrun) oil and gas discovery and 220 kilometers west of Stavanger. The wells were drilled as sole risk wells by Equinor and Neptune Energy Norge.
The primary and secondary exploration targets for wildcat well 15/3-12 S were to prove petroleum in Middle and Upper Jurassic reservoir rocks (the Hugin and Draupne Formations), respectively.
The well encountered three separate oil-filled reservoir zones of 9, 4 and 9 meters in the Hugin Formation, which are about 100 meters thick. The reservoir zones mainly have moderate reservoir quality. The oil/water contacts were not encountered.
The exploration target for wildcat well 15/3-12 A was to prove petroleum in Upper and Middle Jurassic reservoir rocks (the Draupne and Hugin Formations), respectively.
Preliminary estimates place the size of the oil discovery between 1.0 and 2.7 million standard cubic meters (Sm3) of recoverable oil. The development of the discovery as a tie-in to the Gudrun field will be considered.
No formation tests were performed, but extensive volumes of data have been collected and samples have been taken.
The wells 15/3-12 S and 15/3-12 A were drilled to respective vertical depths of 3652 and 3796 meters below sea level, and respective measured depths of 3771 and 3999 meters below sea level.
