In March 2014, RWE AG agreed to sell its upstream exploration and production portion of the group to LetterOne (L1). The deal valued the upstream business unit at US$7.1 billion and concluded in early 2015, and is now known simply as DEA. The company's exploration strategy includes a mix of near field drilling and frontier activity, concentrating on its five core countries (Norway, Germany, Denmark, Egypt and Algeria). In Europe, the company targets areas with existing infrastructure in Norway, onshore Germany, and Denmark. It has aggressively built its portfolio in Norway through, giving it a large inventory of prospects to target. Its priority in the region is to bring new discoveries onstream quickly.
