Spanish energy group Repsol on Monday said it will invest $768 million in an Alaskan oil exploration deal it has reached with 70 & 148 LLC and GMT Exploration LLC. Repsol will have a 70% stake in the joint venture with those two companies, working on oil-rich onshore blocks on the North Slope of Alaska. The total investment represents the amount Repsol will pay to those partners and the cost of exploration over the course of several years.
