Blackrock well cuts thin oil sands off UK

The Blackrock exploration well 204/5b-2 in the West of Shetlands area proved the existence of intravolcanic charged reservoirs between undeveloped Cambo and Rosebank oil fields, reports Siccar Point Energy, the operator. The Diamond Ocean GreatWhite semisubmisersible rig drilled the well in 1,115 m of water 10 km north of Cambo field.

The Blackrock exploration well 204/5b-2 in the West of Shetlands area proved the existence of intravolcanic charged reservoirs between undeveloped Cambo and Rosebank oil fields, reports Siccar Point Energy, the operator (OGJ Online, Mar. 19, 2019).

The Diamond Ocean GreatWhite semisubmisersible rig drilled the well in 1,115 m of water 10 km north of Cambo field.

The well targeted intravolcanic Paleocene Flett reservoirs of the Colsay member on trend with equivalent oil-filled sandstones in Rosebank field.

It encountered a 34-m gross package of intravolcanic siliclastic sediments with “a number of thin oil-bearing sandstones” from which Siccar Point recovered samples. The well also encountered gas in the overlying Hildasay supravolcanic member.

Siccar Point holds a 52.5% interest in the P1830 license with partners Suncor, 25%, and Shell, 22.5%.
