LONDON — Neptune Energy has confirmed a commercial oil discovery from its Ofelia exploration well in the Norwegian North Sea, close to its Gjøa Field complex.
The Deepsea Yantai semisubmersible drilled well 35/6-3 S in PL 929 in 344 m of water, 15 km north of the Gjøa platform, encountering oil in the Agat Formation sandstones. As the company pointed out, this is a reservoir that until recently was not one of the mainstream exploration models on the Norwegian Shelf.
Duva was the first find in the Agat (now onstream), while the second was Hamlet, with estimated recoverable volumes of 8 MMboe to 24 MMboe.
Initial analysis suggests Ofelia holds 16 MMboe to 39 MMboe, with upside of about 10 MMboe recoverable gas in the shallower overlying Kyrre Formation.
Neptune and its partners will assess options for developing both Hamlet and Ofelia as tiebacks to Gjøa.
Director of Exploration & Development in Norway, Steinar Meland, said, “The Ofelia discovery underlines the strength of our exploration strategy and confirms the high prospectivity potential of the area around Gjøa, where we have several more exciting exploration opportunities.”
Earlier this week Neptune Energy said it started drilling a 10th production well at the Cygnus gas field in the southern North Sea. Upon completion later this year, the Cygnus gas facility should be capable of producing sufficient gas for about 2 million UK households, Neptune said. Borr Drilling’s Prospector 1 jackup is drilling the Cygnus well.
