Faroe Petroleum has reported further success in the appraisal of Brasse discovery in the Norwegian North Sea.
Drilled to a total depth of 2,275m TVDSS, the 31/7-2A Brasse sidetrack appraisal well successfully penetrated the gas-oil contact and the oil-water contact in the southern part of Brasse field.
The well targeted the reservoir 1km west of the appraisal well 31/7-2 and 2.4km south of the main discovery well 31/7-1.
Faroe carried out an extensive data acquisition programme in the sidetrack, which includes cutting of cores together with a full suite of wireline logs and fluid samples.
The well encountered nearly 18m of gross oil-bearing and 4m of gross gas-bearing Jurassic reservoir above the oil water contact.
According to the initial results, the well found oil in a sand-rich reservoir of good quality with the same oil-water contact as in the 31/7-1 and 31/7-2 wells.
Faroe Petroleum chief executive Graham Stewart said: "We are very pleased to announce the completion of this successful, Faroe-operated, appraisal programme of the Brasse field, which considerably exceeded expectations and further confirms the commerciality of this discovery.
"The programme has established excellent reservoir quality and reservoir communication, together with excellent flow rates, even at the periphery of the field."
With this discovery, the total gross volumes of recoverable hydrocarbons for the Brasse field have been revised up to 46 million to 76 million barrels of oil, and 59 billion to 97 billion cubic feet of dry gas.
Brasse discovery is situated within tie-back distance to Wintershall-operated Brage field platform and Statoil-operated Oseberg Field Centre.
Extensive feasibility studies of the Brasse field development are currently underway.
The field is equally owned by Faroe and Point Resources and expected to deliver its first oil in 2020-21 with initial flow rates of above 30,000boe/d.
