The continental resources that Continental Resources searches for are oil and natural gas assets beneath the North American continent, in the Rocky Mountain, Mid-Continent, and Gulf Coast regions. The independent oil and gas exploration and production company has grown substantially through internal growth (aka "growing through the drill bit"). It holds 1.2 million net acres of undeveloped leasehold properties. In 2015 Continental Resources reported estimated proved reserves of 1.2 billion barrels of oil equivalent (about 43% of which were developed and 68% located in the North region); and 2,100 net producing wells.
