Equinor and its partners have commenced production from the Utgard gas and condensate field, which covers the Norwegian-UK border in the North Sea.
Discovered in 1982, the Utgard field development comprises two wells from a subsea template tied back to the Sleipner field using a pipeline and an umbilical.
The subsea template has one well on each side and is installed on the Norwegian side of the border.
Recoverable resources at the field are estimated to be at around 40 million barrels of oil equivalent (Mboe) and daily production on plateau will be around 43,000boe.
Equinor acquired the UK share of the discovery in 2016 to realise its development. During the same year, the plan for development and operation and the field development plan were submitted to Norwegian and UK authorities.
The cost estimate during that time was Nkr3.5bn ($391m) and operations were scheduled for the end of this year.
Equinor Technology, Projects and Drilling executive vice-president Anders Opedal said: “I am proud of the Utgard project being delivered at Nkr900m below the cost estimate and ahead of schedule, but first and foremost of the project being delivered without personal injuries.”
“Good and efficient cross-border cooperation with both licence partners and authorities has made the Utgard development possible, and I am pleased that we found solutions ensuring proper resource management on both sides.”
The Utgard field will be remotely operated from the Norwegian Sleipner field, where the well stream will be processed prior to transporting dry gas to the market through the Gassled pipeline system.
Liquids would be transported to Kårstø through the existing pipeline for further exportation to Europe.
Utgard will also use Sleipner’s facility for the purification and storage of CO2.
