Siccar Point Energy (‘Siccar Point’) has completed drilling the Blackrock exploration well 204/5b-2 in the West of Shetland. The well was drilled with the Diamond Ocean GreatWhite semi-submersible on Licence P1830 in 1,115m of water, 10km north of the Siccar Point operated Cambo field.
The target of the well was the intravolcanic Paleocene Flett reservoirs of the Colsay Member which lie on-trend with equivalent oil filled sandstones in the Rosebank field. The well encountered a 34m gross package of intra-volcanic siliciclastic sediments which contained a number of thin oil bearing sandstones from which oil samples were obtained. Gas was also encountered in the overlying Hildasay supravolcanic Member.
The well has proven the existence of intra-volcanic charged reservoirs between the Cambo and Rosebank fields. The well results will now be incorporated with existing regional data to better define and target thicker reservoir packages.
The P1830 partnership are Siccar Point (52.5%), Suncor (25.0%) and Shell (22.5%).
Jonathan Roger, CEO of Siccar Point said: “I am very encouraged by this well result and look forward to further exploring this material exploration play with our partners.”
