Tourmaline, a gas producer, agreed to acquire Black Swan Energy, a Calgary-based private energy company, for $907m. "Tourmaline envisions the North Montney as the key sub-basin for supplying Canadian LNG, as the company expects the North Montney to be the primary growth driver in the entire Western Canadian Sedimentary Basin for the next decade. The Black Swan acquisition complements Tourmaline’s core Gundy development and, along with the more recent Polar Star, Chinook, and Saguaro transactions, will establish Tourmaline as the largest current North Montney producer with the most extensive future drilling and project inventory," Tourmaline.
