Tex. Natural Resources Code § 115.034

(a) If, on the trial of the action, the oil or petroleum product in controversy is found to be unlawful, the court shall render judgment forfeiting the oil or petroleum product to this state. The court shall issue an order of sale directing the sheriff or a constable of the county in which the oil or petroleum product is located to seize and sell the oil or petroleum product in the same manner as personal property is sold under execution. The court may order the oil or petroleum product sold in whole or in part.

(b) The sale shall be conducted at the courthouse door of the county in which the oil or petroleum product is located.

(c) The court shall apply the money realized from the sale first to the payment of the costs of the action and expenses incident to the sale of the oil or petroleum product. The court may then use not more than one-half of the money to compensate a person for expenses incurred in storing the unlawful oil or petroleum product. Any balance remaining shall be remitted to the comptroller.

(d) The officers of the court shall receive the same fees provided by law for other civil actions. The sheriff who executes the sale shall issue a bill of sale or certificate to the purchaser of the oil or petroleum product, and the commission, on presentation of that certificate of clearance, shall issue a tender, if a tender is required, permitting the purchaser of the oil or petroleum product to move the oil or petroleum product into commerce.
