Wellesley Petroleum an exploration firm centered on the Norwegian Continental Shelf pronounces the profitable appraisal of the Grosbeak Discovery within the Northern North Sea by wells 35/11-21S and 35/11-21A. The wells have been drilled in manufacturing licence PI248I the place Wellesley holds a 60% operated curiosity.
Well 35/11-21S encountered a gross oil column of 90 metres on the goal Middle Jurassic Brent Group degree. Within this oil column, 45 metres comprised internet reservoir with good to glorious reservoir properties. Extensive knowledge was acquired from the reservoir interval together with a profitable effectively take a look at which confirmed the prime quality and good connectivity of the reservoir.

Pressure knowledge from these sandstones signifies good connectivity to the zone examined within the 35/11-21S effectively.
The up to date vary of recoverable assets within the Grosbeak Discovery is 53 – 115 million barrels of oil plus 269 – 432 billion cubic ft of fuel. The 35/11-21S and A wells have been plugged and deserted and improvement research will begin.
Chris Elliott, CEO of the Wellesley Group of corporations, commented “This is a really optimistic finish to our operated drilling marketing campaign within the Grosbeak space. Our pre-drill subsurface research of Grosbeak indicated that the Brent Group sandstones have been each predictable and effectively linked and this has been demonstrated by the appraisal wells, considerably decreasing the event threat of this reservoir. The discovery of a separate, glorious high quality fuel reservoir within the Upper Jurassic additionally provides vital assets to what we count on to be a fabric and commercially strong future improvement.”
Wells 35/11-21 S and A have been drilled by the Transocean Arctic, which can now drill wildcat effectively 30/6-30 within the northern North Sea in manufacturing licence 825, the place Faroe Petroleum is the operator. (Source and picture: Wellesley Petroleum)
