You left out information needed to answer your question, was your name the owner of record along with your address prior to the well being drilled and you signed a lease or were you pooled as it seems unlikely they would not have put you in pay status from the beginning had you signed a lease, you were owner of record without title issues and they had your address?
Here is the Oklahoma state statute concerning payments:
§52-570.10. Payment of proceeds from sale of oil and gas production.
A. All proceeds from the sale of production shall be regarded as separate and distinct from all other funds of any person receiving or holding the same until such time as such proceeds are paid to the owners legally entitled thereto. Any person holding revenue or proceeds from the sale of production shall hold such revenue or proceeds for the benefit of the owners legally entitled thereto. Nothing in this subsection shall create an express trust.
B. Except as otherwise provided in this section:
1. Proceeds from the sale of oil or gas production from an oil or gas well shall be paid to persons legally entitled thereto:
a. commencing not later than six (6) months after the date of first sale, and
b. thereafter not later than the last day of the second succeeding month after the end of the month within which such production is sold.
2. Notwithstanding paragraph 1 above, royalty proceeds from the sale of gas production from an oil or gas well remitted to the operator pursuant to subsection B of Section 570.4 of this title shall be paid to persons legally entitled thereto:
a. commencing not later than six (6) months after the date of first sale, and
b. thereafter not later than the last day of the third succeeding month after the end of the month within which such production is sold; provided, however, when proceeds are received by the operator in its capacity as a producing owner, the operator may pay the royalty share of such proceeds to the royalty interest owners legally entitled thereto at the same time that it pays the royalty proceeds received from other producing owners for the same production month, but not later than the last day of the third succeeding month after the end of the month within which such production was sold.
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, 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.
4. Any delay in determining the persons legally entitled to proceeds from production caused by unmarketable title shall not affect payments to persons whose title is marketable.
C. 1. A first purchaser that pays or causes to be paid proceeds from production to the producing owner of such production or, at the direction of the producing owner, pays or causes to be paid royalty proceeds from production to:
a. the royalty interest owners legally entitled thereto, or
b. the operator of the well,
shall not thereafter be liable for such proceeds so paid and shall have thereby discharged its duty to pay those proceeds on such production.
2. A working interest owner that pays or causes to be paid royalty proceeds from production to:
a. the royalty interest owners legally entitled thereto, or
b. the operator of the well,
shall not thereafter be liable for such proceeds so paid and shall have thereby discharged its duty to pay those proceeds on such production.
3. An operator that pays or causes to be paid royalty proceeds from production, received by it as operator, to the royalty interest owners legally entitled thereto shall not thereafter be liable for such proceeds so paid and shall have thereby discharged its duty to pay those proceeds on such production.
4. Where royalty proceeds are paid incorrectly as a result of an error or omission, the party whose error or omission caused the incorrect royalty payments shall be liable for the additional royalty proceeds on such production and all resulting costs or damages incurred by the party making the incorrect payment.
D. 1. Except as otherwise provided in paragraph 2 of this subsection, where proceeds from the sale of oil or gas production or some portion of such proceeds are not paid prior to the end of the applicable time periods provided in this section, that portion not timely paid shall earn interest at the rate of twelve percent (12%) per annum to be compounded annually, calculated from the end of the month in which such production is sold until the day paid.
