Okla. Stat. tit. 17, § 514

Neither the unit production nor proceeds from the sale thereof shall be treated, regarded or taxed as income or profits to the unit. Instead, such receipts shall be the income of the several persons to whom same are payable under the plan of unitization. To the extent the unit may receive or disburse any receipts it shall only do so as a common administrative agent of the persons to whom the same are payable.
