BG Group reports the discovery of natural gas in Block 47/15b, Rose R2, in the Southern North Sea. The discovery lies within the Leman Sandstone play fairway 34 miles east of the Easington Terminal and 5 miles north-east of the Amethyst field. This well was drilling by Santa Fe International's jackup, Monarch. During testing, the well flowed at a maximum sand free rate of 30 million standard cubic feet per day of natural gas and 90 barrels per day of condensate on a 68/64th inch choke. These rates were constrained by the limits of the testing equipment. Further studies are needed to fully evaluate the discovery.
In 1998 BG drilled the first discovery well in Block 47/15b, which tested the Rose East prospect with deviated well 47/10-6. The well flowed natural gas at 27.3 million standard cubic feet per day.
BG is the operator and has a 60% interest in the Block, with Amerada Hess holding other 40%.
