Any person who engages in well drilling activities shall obtain a well driller's license issued by the state engineer (except, under New Mexico state law, a well driller's license is not required for driven wells that do not require the use of a drill rig and which have an outside casing diameter of two and three-eighths (2 3/8) inches or less). A person found engaged in the business of well drilling within the state of New Mexico without a license can be prosecuted in accordance with New Mexico statutes.
