This data is provided by the NM OCD and is derived from weekly activity reports that log such information as requests for permits to drill, zone abandonments, well pluggins, operator or well name changes, and other miscellaneous changes. It is typically updated weekly, with the maps updated monthly. For other activity information, please see the Inactive Wells page. Please note that a well date with a year of 1900 denotes a well with no completion, not a well drilled in that year.
