About this data

New Mexico Oil Conservation Division (OCD), from its public database extracts. Status and type are in OCD's own words. Production and injection are what operators filed on form C-115, by well and month; twelve-month figures end in Aug 2026, the last month whose filings are in. Locations are from the well's location plat and are approximate. Production and injection filed before January 1993 are in lifetime totals as the Division's totals to that date, and in no month or year. Nothing is estimated.
