I have some mineral acres in Fayette county on which the lease expired. I sent the owners of the lease (the oil company) a request for a ‘RELEASE OF OIL AND GAS LEASE’. In quotes, this is how the last paragraph reads…“NOW, THEREFORE, Argent Energy (US) Holdings Inc. for and in consideration of the sum of One Dollar ($1.00) and other good and valuable consideration, the receipt of which is hereby acknowledged, does hereby release, relinquish and surrender to the Lessors therein named, their heirs, successors or assigns, all of the right, title and interest of Argent Energy (US) Holdings Inc., in and to said lease.”… This was dated August 2015. I’m still waiting for someone else to contact me about leasing it again. Good luck.
