Faroe Petroleum has failed to find hydrocarbons at its Brasse East exploration well in the Norwegian North Sea, while the Brasse appraisal sidetrack well encountered hydrocarbons.
The Aberdeen-headquartered firm said that the Brasse East exploration well 31/7-3 S was drilled to a total depth of 2,247 metres below sea level. The well targeted a separate structure located to the east of the Brasse field. The well encountered 48 metres of gross Jurassic reservoir with excellent properties, but was found to be water wet. Data acquisition was undertaken including coring and logging.
The Brasse appraisal well 31/7-3 A sidetrack, planned as a further appraisal of the northern part of the Brasse field, was drilled to a total depth of 2,254 metres below sea level. Preliminary analysis of the log data acquired whilst drilling, indicates the well encountered approximately 40 metres of gross hydrocarbon-bearing Jurassic reservoir.
Both the reservoir depths and the hydrocarbon contact are similar to the pre-drill expectations. Further wireline logging is ongoing which will be incorporated into the final well results.
Drilling operations are being undertaken using the semi-submersible Transocean Arctic rig.
Graham Stewart, Chief Executive of Faroe Petroleum, said: “Although no hydrocarbons were present in the Brasse East prospect we are pleased with the results of the appraisal sidetrack which confirms hydrocarbons within the northern part of the Brasse field, as expected. In addition, the excellent sand quality in the Brasse East Exploration well has reduced the reservoir risk of the Brasse Extension exploration prospect located to the north east of the Brasse field.”
