PDO submitted for Frosk development in Alvheim area

Aker BP and licence partners Vår Energi AS and Lundin Energy Norway AS have submitted a plan for development and operation (PDO) for the Frosk field to the Ministry of Petroleum and Energy (MPE). The development will contribute to production and reduce unit costs in the Alvheim area by utilising existing infrastructure.

The Frosk field, located approximately 25 km southwest of the Alvheim FPSO in the North Sea, will be tied back to the FPSO via the existing Bøyla and Alvheim subsea infrastructure. Total investments are projected at around NOK2 billion (approximately US$230 million). Production is scheduled to start in 1Q23. Recoverable reserves in Frosk are estimated at around 10 million boe.

The Frosk discovery, located in an injectite sandstone reservoir, was made in 2018. Frosk Test Producer commenced in 2019 with the purpose of collecting data to reduce uncertainty.

Test production has provided valuable reservoir data that has been used to optimise the number of wells, drainage strategy and surface facility requirements for the Frosk field.

The concept is a subsea development connected to the Bøyla subsea infrastructure. Two new production wells are to be drilled to effectively drain the remaining areas of the Frosk field. The project has been matured over the two years since test production commenced, and the proposed solution enables a fast-track development with first oil planned 18 months after PDO submission.

On the Frosk project, the Semi Alliance (Aker BP, Odfjell Drilling, Halliburton) for drilling and completions of new wells and the Subsea Alliance (Aker BP, Subsea 7, Aker Solutions) for execution of the subsea facilities scope will contribute.

The Frosk development will result in reduced OPEX- and CO2 per barrel from the Alvheim FPSO from start-up in 2023, one year before the Kobra East and Gekko (KEG) development is planned to come on stream. PDO for KEG was submitted to the MPE in June.

"The Frosk development underpins the prolonged Alvheim success story that both we and our partners can be proud of. The Alvheim area is among the most cost-efficient developments on the Norwegian continental shelf, and the resource base has multiplied since start-up. This is the result of targeted exploration and reservoir development, technological innovation and, not least, close collaboration with the joint venture partners and suppliers,” said Aker BP CEO, Karl Johnny Hersvik.
