0077874499 2018-06-07 Production Wells No Violations At the time of this inspection, the well was a casing well. The 4.5 inch casing valve was open and the two inch flow line valve was open. Production records were current. The production equipment consisted of a heater treater separator. Valves on the separator were open. There was a domestic supply plumbed off the separator with a regulator and meter. The separator had legible signage. The lease access was stable. No violations observed.
1062951320 2015-08-05 Production Wells No Violations I was on location for a status check. During my inspection, I found the well in production. The well is equipped with a plunger lift assembly. The tank battery consists of a 100 barrel production tank and a mechanical separator. A dike surrounds the tank. There is a faded identification sign on the separator. A plug has been installed on the load line. A domestic gas line comes off of the 2 sales line at the separator. The lease road is in stable condition. I spoke with the well tender on location and instructed him to replace the identification sign by 8/26/2015. A follow-up inspection will be conducted.
