Abstract:

Beatrice field is located in Block 11/30 in the United Kingdom sector of the North Sea. The field lies just 14 mi (22.4 km) from the Scottish coast. The water depth is 160 ft (49 m). In August 1976, well 11/30-1, the seventh wildcat in the subbasin, discovered oil at about 6,000 ft (1,800 m) in an 831-ft (253 m) gross column, at a time when most companies had written off the inner Moray Firth as a major oil province. The well produced an aggregate of 6,060 BOPD (38° API) with a low GOR. The crude, though light and sweet, has a high wax content (17%) and high pour point (65°F; 18.3°C).

An additional four wells, three productive and one dry, have delineated the 4,271-acre (1,728 ha.) field, in which there are an estimated 476 million bbl of oil in place (162 million bbl recoverable).

The field reservoir is an alluvial to marine Jurassic (Sinemurian-Callovian) sandstone and shale sequence. Stratigraphic markers within the sequence can be related to outcrops fringing the Moray Firth. The oil accumulation is in an elongate, fault-bounded anticlinal trap.
