Notwithstanding any provision to the contrary in section 187 of this title, a lessee may at any time make and file in the appropriate land office a written relinquishment of all rights under any oil or gas lease issued under the authority of this chapter or of any legal subdivision of the area included within any such lease. Such relinquishment shall be effective as of the date of its filing, subject to the continued obligation of the lessee and his surety to make payment of all accrued rentals and royalties and to place all wells on the lands to be relinquished in condition for suspension or abandonment in accordance with the applicable lease terms and regulations; thereupon the lessee shall be released of all obligations thereafter accruing under said lease with respect to the lands relinquished, but no such relinquishment shall release such lessee, or his bond, from any liability for breach of any obligation of the lease, other than an obligation to drill, accrued at the date of the relinquishment.
