The preliminary analysis at the well indicates that it encountered the targeted Oligocene Upper and Lower Gabus Formation sandstone in well developed reservoirs, while no hydrocarbons were encountered.
At a total depth of 2,109m below mean sea level (MSL), the Balqis-1 well reached basement, noted Lundin.
The company plans to plug and abandon the lower section of the Balqis-1, while drilling of the Boni-1 exploration side-track well will commence below the Balqis-1 9 5/8 casing shoe.
Against the basement of about 800m to the west of the vertical Balqis-1 well, the Boni-1 side-track well will test the stratigraphic on-lap play of the Lower Gabus Formation sandstones.
According to Lundin, the Boni prospect is expected to contain unrisked, gross, prospective resources of 55 million barrels oil equivalent (MMboe), while the planned total vertical depth of the well is about 2,300m below MSL.
Lundin Baronang, a wholly owned subsidiary of Lundin Petroleum is the operator of the Baronang PSC with 85% interest, while Nido Petroleum holds the remaining 15% stake.
