VIENNA, Aug 9 (Reuters) - Austrian energy group OMV OMVV.VI has agreed to sell most of its 50 percent stake in the British Rosebank field to Canada's Suncor Energy SU.TO for as much as $215 million, OMV said on Tuesday.
OMV said it would also book a pre-tax impairment charge of 530 million euros ($589 million) in the second quarter for its stake in the field, which would shrink to 20 percent.
OMV is due to report its second-quarter results on Wednesday. Chevron (NYSE:CVX) holds a 40 percent share of the Rosebank project while Denmark's Dong Energy DENERG.CO holds the remaining 10 percent. ($1 = 0.8998 euros)
