Regarding the annual payment - unless there is some other agreement in force, operators must distribute royalties at least as often as required by the Oklahoma Production Revenue Standards Act (52 OS 570) as set out in Section 570.10(3):
a. Proceeds from production may be remitted to the persons entitled to such proceeds annually for the twelve (12) months accumulation of proceeds totaling at least Ten Dollars ($10.00) but less than One Hundred Dollars ($100.00). Amounts less than Ten Dollars ($10.00) may be held but shall be remitted when production ceases or by the payor upon relinquishment of payment responsibility.
b. Proceeds totaling less than One Hundred Dollars ($100.00) but more than Twenty-five Dollars ($25.00) shall be remitted monthly if requested by the person entitled to the proceeds. Amounts less than Ten Dollars ($10.00) shall be remitted annually if requested by the person entitled to the proceeds.
c. Before proceeds greater than Twenty-five Dollars ($25.00) may be accumulated, the payor shall provide notice to the person owning interest as defined in Section 570.2 of this title, entitled to such proceeds that there is an option to be paid monthly for proceeds greater than Twenty-five Dollars ($25.00). Such notice to the person shall also provide directions for requesting monthly payment, and constitutes notice to all heirs, successors, representatives, and assigns of the person.
