Dominion Resources Black Warrior Trust knows that when the wells get old, financial warriors (aka shareholders) don't give up on the economic possibilities. The trust holds royalty interests in 532 natural gas producing wells and is set to terminate when these wells no longer produce enough gas to be profitable. The trust receives, then distributes to shareholders, 65% of the gross proceeds that Dominion Resources (via its subsidiary Dominion Black Warrior Basin) earns by selling the natural gas from its wells in the Black Warrior Basin of Alabama. In 2008 the trust had proved reserves of 22.6 billion cu. ft. of natural gas equivalent.
