Draugen license operator Okea ASA and partners Petoro AS and Neptune Energy Norge AS have made the decision to develop the Norwegian Sea Hasselmus gas discovery. Hasselmus will be the first tie-back to the Draugen production platform and will add over 4,000 boe/d to production, Okea said in a June 1 statement.
The Hasselmus project is expected to recover some 10.6 MMboe as fuel and export gas and will also make possible the restart of export of associated gas including NGL which is currently being injected into the reservoir.
The development concept is a single subsea well with direct tie-back to the Draugen platform. Production start-up is planned for fourth-quarter 2023 with plateau gas production of more than 4,400 boe/d gross. Expected gross total investment for the project is 2.4 billion kroner.
The Hasselmus gas discovery lies on the western edge of the Trøndelag platform, 7 km northwest of the Draugen platform, in production license 093. A single well (6407/9-9 T2) was drilled on the Hasselmus structure by A/S Norske Shell in 1999 which encountered a 16-m gas column and a 6.8-m oil column in high quality sands at a depth of 1,700 m.
Okea is operator of the license and the project with 44.56% working interest. Partners are Petoro AS (47.88%) and Neptune Energy Norge AS (7.56%).
