In 2010, more than 53,000 wells produced oil and gas in New Mexico. That year, there were just 12 New Mexico Oil Conservation Division (OCD) inspectors to oversee these wells: that is more than 4,000 wells per inspector, which is the most unfavorable ratio of any state  that we analyzed.
To visit every producing well at least once per year, OCD inspectors would each have to inspect more than 15 wells per day. Needless to say, OCD did not.
A lack of inspection capacity has been a problem in New Mexico for years. In 2008 it was reported that OCD inspectors in the Aztec office made an effort to inspect each of the district’s 24,000 active wells once every five years. That year, the entire state of New Mexico employed 18 inspectors. In 2011, there were six fewer inspectors in the state , so it almost certain that wells inspected by the Aztec office of OCD are still only inspected once every five years, at most.
New Mexico’s inspection capacity lags behind other states
Compared to other oil and gas states , New Mexico’s inspection capacity is low. As seen in the map, in 2010 Pennsylvania had 65 inspectors to monitor 90,000 active wells and New York state had 16 inspectors to monitor approximately 10,000 active wells. Meanwhile, New Mexico OCD had 12 inspectors to monitor more than 50,000 wells in a state that is larger than New York and Pennsylvania combined.
OCD inspectors have a higher inspection burden than their counterparts in other states. In 2010, New Mexico inspectors carried out, on average, 1,732 inspections each. In 2011, OCD increased its number of oil and gas inspections by more than 5,000, but retained the same number of inspectors. So each inspector carried out an average of 2,129 inspections , and possibly as many as 2,450, in 2011.
Inspectors in other states conduct far fewer inspections . In 2011, Texas and Colorado inspectors each performed approximately 1,184 and 816 inspections, respectively, and Ohio and Pennsylvania inspectors each carried out fewer than 400 inspections per year. It seems reasonable to assume that an inspector who conducts 400 or 1,000 inspections per year can do so in a much more thorough manner than an inspector who conducts more than 2,000 inspections per year.
Clearly, there is a critical need to increase the number of inspectors in the state – both to decrease the burden on existing inspectors, and to increase OCD’s capacity to inspect more wells on an annual basis. If staffing levels increase, all new hires should be put toward inspections, not to processing permit applications, until OCD can provide adequate oversight for all of its existing wells.
