British gas group, BG has said it had informed the government of Oman its decision to relinquish its Block 60 concession in the Sultanate, despite having found gas and condensates with each of the seven appraisal wells it had drilled, The National has reported. The UK-based firm said the move aims to "prioritise its other opportunities across the globe for development." The block contains the Abu Butabul gas and condensate reservoir, discovered in 1998, which has proved technically challenging to develop.
