OSLO -- DNO has made an oil discovery, following the interpretation of the license potential of P1067 - block 211/22b, based on re-evaluation of well 211/22-2 data.

The well was drilled, logged, and cored in 1977 by Sun Oil; however, no drill stem test was undertaken at the time. Based on a full re-evaluation of available log and core data, as well as correlation with neighboring wells, the well is considered to be a discovery of a 20-m (66-ft) oil column within the Brent group.

This is now identified as the Mulle discovery, estimated to contain gross recoverable reserves between 4 MMboe (low) and 36 MMboe (high), with a mid case of 17 MMboe within the P1067 license, according to DNO.

The license group will now focus on maturing the discovery further, including a possible appraisal well. The company plans to develop the discovery as a subsea tie-in to existing or planned neighboring infrastructure.

The Mulle prospect is located downdip of the Causeway field operated by Antrim Energy.
