Wintershall Norge AS expects production to begin in 2021 from Nova field (formerly Skarfjell) in the northeastern North Sea, for which it received development and operation approval from the Ministry of Petroleum and Energy (OGJ Online, May 16, 2018).
The field, 120 km northwest of Bergen, Norway, will be developed as a subsea tie-back connecting two templates to the Neptune Energy-operated Gjoa platform for processing and export. Nova is 17 km southwest of Gjoa. Gjoa also will provide lift gas to the field and water injection for pressure support. Power for Nova field comes via the Gjoa platform from shore.
A subsea production system contract, let to Aker Solutions, consists of two templates with manifolds, seven subsea trees including one spare, umbilicals, and associated tie-in and controls equipment. A pipeline and subsea construction contract was let to Subsea 7. Another contract secures Seadrill Norway Operations Ltd. to operate the West Mira semisubmersible on behalf of Northern Drilling (OGJ Online, July 3, 2018).
Investment in the Nova development is estimated at €1.1 billion. Recoverable reserves of the field are estimated at 80 million boe, the majority of which is oil, Wintershall said.
Nova will be Wintershall Norge’s third operated subsea field, after Vega, which is also tied back to the Gjoa platform, and and Maria in the Norwegian Sea.
Nova interests are operator Wintershall 35%, Capricorn Norge AS and Spirit Energy, 20% each, Edison Norge AS 15%, and DEA Norge AS 10%.
