Beginning January 1, 1980, when taxes on oil and gas leaseholds and lands are due, such taxes shall be a debt due from the owner or the unit operator as the case may be and shall be recoverable by the treasurer by direct action in debt; except that such taxes treated as debt due from a fractional interest owner shall not exceed the amount of taxes for which the fractional owner is liable, as provided in section 39-10-106 . The treasurer may also collect such debt as if the property were personal property.
