The price paid under an arm's-length contract, between parties other than the person paying the tax, for the purchase or sale of oil of like kind, character, and quality, in the same field or, if none, in a nearby field, less, when applicable, transportation costs associated with moving the oil from the point of production to the point of sale.3. The value determined by consideration of the posted price relevant in valuing oil of like kind, character, and quality, in the same field or, if none, in a nearby field, less, when applicable, adjustments for transportation costs to reflect the differential between the value at the point of production and the value at the location reflected in the posted price.
