Collection consists of 88310 paper well logs (including mud logs) from 46808 oil and gas wells, which are located almost exclusively within New Mexico, with a small percentage of the well logs in our collection coming from the neighboring states of Arizona, Utah, Colorado, and Texas. This collection has been built over the past 60 years by accepting donated well logs. Many of the logs contain significant handwritten material such as formation tops, perforated, intervals, etc. Please contact us for a copy of our current log list.
