Woodside Petroleum, an Australian petroleum exploration and production company, completed the acquisition of a 40% stake in Senegal assets of Cairn Energy, an independent oil and gas exploration and development firm, for $300m. "We are proud of what Cairn has achieved in Senegal. Our discoveries were the country’s first deep-water wells and opened up a new basin play on the Atlantic Margin. What’s more, they successfully laid the foundations for Senegal’s first oil and gas development, which will deliver enduring benefits to its people," Simon Thomson, Cairn CEO.
