The official News Agency of Nigeria said on Friday that the contracts for blocks 332 and 278 were the only two of the 18 oil block winners who had paid their signature bonuses during the 2005 licensing round. The deals also involved five indigenous companies that would serve as local content vehicles, it said. The combined signature bonus of the two oil blocks is 77 million U.S. dollars with BG's block 332 valued at 51.5 million dollars and Oando's block 278 at 25.5 million dollars. BG in a statement issued on Friday said that it acquired a 45 percent interest in, and operatorship of, block 332 under the agreement, which marks the group's entry into the Nigerian upstream sector. "Nigeria is a prolific hydrocarbon province which fits well with our market focused Atlantic Basin strategy," said Stuart Fysh,BG executive vice president for the Mediterranean Basin and Africa.
