It has nothing to do with the leases really. Most of those pulled where ones nobody wanted. It is this administration is so anti oil/gas that no oil company, refinery etc... want to hedge any more money on developments, research, building anything and then lose it all. This administration wants you in battery cars be damned if that is not feasible nor environmentally safe, nor done with out relying on Chinese metals and on and on.
But they will all get richer than they are while you toe the line. The more they take and grind us down the more people stick their hands out and the bigger and more controlling the Democrat madness gets.
