Section 15-36-305 - Determination of gross value of product(1) The total gross value of all oil or natural gas produced and sold each quarter must be determined by taking the total number of barrels or cubic feet of oil or natural gas produced and sold each month at the average value at the mouth of the well during the month that the oil or natural gas is produced and sold, as determined by the department. However, in computing the total number of barrels of oil or cubic feet of gas produced and sold, there must be deducted the amount of oil or gas used by the person in connection with the operation of the well from which the oil or gas is produced or for pumping the oil or gas from the well to a tank or pipeline.(2) For the purposes of determining average value at the mouth of a well, a fee of up to 25 cents a barrel paid to the operator or producer to administer royalty payments, whether or not the fee is payable on a per barrel basis, may not be considered a part of the value of the oil.En.
