The Norwegian oil and gas company Equinor started production from the Trestakk subsea field on Haltenbanken in the Norwegian Sea on Tuesday, July 16. In the meantime, the company published a video presenting the procedure from A to Z, for an offshore field to come online.
According to Equinor, the field has estimated recoverable resources of 76 million barrels of oil.
When the project was approved by the authorities in 2017, the investments were estimated at NOK 5.5 billion (current). On field start-up the final costs are expected to be NOK 5 billion.
Anders Opedal, executive vice president for Technology, Projects and Drilling in Equinor, commented
Together with our partners ExxonMobil and Vår Energi we spent ample time on maturing Trestakk, and with proper assistance by our main supplier TechnipFMC we arrived at a good and profitable concept with development costs nearly halved before the investment decision was made.
Moreover, the Trestakk field development covers a subsea template with four well slots and one satellite well.
Equinor reported that overall of five wells will be drilled: three for production and two for gas injection.
Concluding, when Trestakk comes on stream it will produce around 22,000 barrels of oil per day (3,500 sm3). Peak production will be around 44,000 barrels of oil per day (7,000 sm3). Trestakk field production is expected to last for 12 years.
