Siccar Point Energy has completed drilling the Blackrock exploration well 204/5b-2 in the West of Shetland.
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 thus proven the existence of intra-volcanic charged reservoirs between the Cambo and Rosebank fields, and Jonathan Roger, CEO of Siccar Point, is “very encouraged by the good result”.
