Neptune Energy Norge AS increased production from the Gjøa platform in the Norwegian North Sea by 2 MMboe from 2020 to 2021. Gross production was 42 MMboe in 2021 compared with 40 MMboe in 2020. Most of the production was gas (76%), all of which is exported through FLAGS pipeline to St. Fergus gas terminal in the UK.
The increased production was due mainly to production start-up from the Gjøa P1 infill development in February and Duva field tieback in August 2021 (OGJ Online, Aug. 23, 2021). In addition, production from the tie-back field Vega, operated by Wintershall Dea, and Gjøa field itself, has been better than expected. Estimated reserves on Gjøa have increased by 38% since the plan for development and production was approved in 2007.
The operator expects to bring on stream a fourth tie-in field to Gjøa infrastructure, Wintershall’s Nova field, said the company’s head of Norway operations, Martin Borthne (OGJ Online, May 11, 2020). “In addition, we plan to drill two exploration wells in the area and continue to mature other nearby discoveries and exploration opportunities as tie-in candidates.”
Gjøa has 73.4 total million std cu m original recoverable reserves (14.9 million oil, 40 million gas, and 18.5 million NGL) with 11.1 million (1 million oil, 7.1 million gas, and 3 million NGL) remaining.
Neptune Energy is operator at Gjøa (30%) with partners Petoro AS (30%), Wintershall Dea Norge AS (28%), and OKEA ASA (12%).
