Equinor has completed the drilling of an appraisal well on the 35/11-23 oil and gas discovery near Fram field in the North Sea, but the well came up dry.
Drilled at about 3km southwest of the Fram field in the northern part of the North Sea, the 35/11-23 A well is located in production licence (PL) 090, where Equinor serves as the operator. It is located 120km north-west of Bergen.
In November, the discovery was proven in two sandstone intervals in Upper Jurassic reservoir rocks (the Sognefjord formation) and in the secondary exploration target in the Brent Group.
According to the Norwegian Petroleum Directorate (NPD), the appraisal well was not drilled down to secondary exploration target. NPD noted that the well discovered water in both sandstone intervals in the Sognefjord formation.
The uppermost has sandstone layers of about 40m with good reservoir quality, while the oil-water contact was proven on the basis of pressure data. Meanwhile, the other sandstone interval has layers of about 30m, also with good to very good reservoir quality.
NPD said that the preliminary estimates of the discovery are placed at 7Sm3 to 16Sm3 of recoverable oil equivalent and the licensees plan to consider tying the discovery into the Troll-Fram area existing infrastructure.
Formation-testing has not been carried out for the well, but extensive data acquisition and sampling have been executed.
The 35/11-23 A, which is the 17th exploration well in production PL 090, was drilled by the Deepsea Atlantic drilling facility. The rig facility will now drill production wells on Snøhvit field in PL 064 in the Barents Sea, operated by Equinor.
