Norwegian oil exploration and development company Aker BP has made an oil and gas discovery of up to 21 million standard cubic metres (Sm3) of recoverable oil equivalents in the Bøyla field in the North Sea.

Aker BP concluded drilling of the wildcat well 24/9-14S and the horizontal appraisal well 24/9-14A. The appraisal well was drilled 2650m northwest of the 24/9-14S wildcat well.

The 24/9-14A and 24/9-14S wells are the first exploration wells in production licence 869 on the Norwegian continental shelf of which Aker BP is the operator, having been awarded the licence in APA 2016. Aker BP discovered reservoirs in the licence in February 2019.

The wells were drilled by the Scarabeo 8 drilling rig, which is set to drill a combined wildcat and test production well in North Sea production licence 340, where Aker BP is also the operator.

The 24/9-14S wildcat well was drilled to respective vertical and measured depths of 2,097m and 2,252m below sea level, with the objective of proving the presence of petroleum and gauging the reservoir potential.

Appraisal well 24/9-14A was drilled to respective vertical and measured depths of 1,847m and 4,398m below sea level, with the objective of investigating the lateral extent and reservoir potential of injectites in the area.

The 24/9-14A well encountered several injectite zones bearing oil and gas totalling 540m, with many sandstone layers with variable reservoir properties.

Wildcat well 24/9-14S encountered an oil column of 38m and a gas column of 30m, which the Norwegian Petroleum Directorate says has“very good to excellent reservoir properties.”

Preliminary estimates place the size of the discovery between 10-21 million Sm3 of recoverable oil equivalents, with the nearby 24/9-3 oil discovery being considered part of this discovery.

Aker BP exploration senior vice president Evy Glørstad-Clark said: “The exploration success at Froskelår Main is an encouraging result of a long-term strategy to unlock the exploration potential in the Alvheim area. This strategy has involved extensive data acquisition and detailed technical analysis.

“The Froskelår Main discovery represents a significant addition to the resource base in the Alvheim area. The discovery also illustrates the significant resource potential yet to be uncovered on the Norwegian Continental Shelf.”
