Nov. 2011 - EnQuest has encountered 52 feet (16 meters) of light oil in excellent quality reservoir sands in the Crathes exploratory well (21/13a-5). The well is currently undergoing wireline logging, before drilling ahead to intersect the Moon prospect. The well is being drilled by the Transocean John Shaw rig (mid-water semisub). The primary exploration target is the Crathes prospect, which lies within the Palaeocene section. The secondary target is the Moon prospect, which lies within the deeper Upper Jurassic section. Recently, Ithaca Energy acquired Challenger Minerals (North Sea) Limited. The acquisition included a dual target exploration opportunity in Block 21/13a alongside the Scolty and Torphins undeveloped discoveries. The operator will evaluate the potential commerciality of the joint development of Scolty, Torphins and Crathes/Moon. EnQuest serves as the operator of the block with a 40 percent interest while Wintershall holds (50 percent) and Ithaca holds (10 percent).
