Canadian Talisman Energy made a significant oil discovery at the Grevling prospect in the Norwegian North Sea. Located in 282 feet (86 meters) of water on Production License 038, wildcat well 15/12-21 was drilled by the Maersk Guardian jackup to a total depth of 10,722 feet (3,268 meters), encountering a 436-foot (133-meter) oil column in the Middle Jurassic and Upper Triassic reservoir rocks.
Talisman serves as operator of the license with 40%; partners include Det norsk oljeselskap with 30% and Petoro with 30%.
Targeting Mesozoic sandstone reservoirs, the discovery well was tested on two zones flowing at a combined rate of 1,250 bopd, confirming the commercial potential of the Grevling field.
An appraisal well is currently being drilled to determine the size of the discovery. The Maersk Guardian is drilling a sidetrack well down-dip to assess the field's upside potential.
Located 10 miles (16 kilometers) north of the Varg field in the southern section of the Central Graben, the potential Grevling field development may include subsea tie-back to the Varg facilities.
