A sidetrack appraisal well on the Brasse discovery in the Norwegian North Sea has encountered a 25-meter (m) gross oil column and a 6-m gross gas column, Faroe Petroleum said in a news release.

Faroe, operator with 50% interest, said the objective of the well—31/7-1A—was to appraise the southeastern part of the hydrocarbon bearing structure previously identified by the main discovery well. The results, which are based on extensive coring, wireline logging and sampling, showed hydrocarbons found in Jurassic reservoir sandstones are similar to those seen in the main well, Faroe said.

Total gross volumes of recoverable hydrocarbons are estimated at between 28 million barrels (MMbbl) and 54 MMbbl of oil and 89 billion cubic feet (Bcf) and 158 Bcf of gas, Faroe said.

As previously reported, the Brasse discovery well (31/7-1) encountered about 21 m of gross oil-bearing and about 18 m of gross gas-bearing Jurassic reservoir.

Options for tieback to existing infrastructure exist, considering the discovery about 13 kilometers (km) away from the Brage, Oseberg Sør and Oseberg field platforms, the release said. Faroe and partner Point Resources will now begin assessing options.
