Hockley County · Levelland field · Shut In · Vertical
May-Montgomery Unit #95 (API 42-219-36878) is a well in Hockley County operated by Hilcorp Energy Company, completed December 17, 2009 and listed as shut in on the RRC schedule, shut in August 1, 2012.
The RRC has issued one drilling permit, issued December 21, 2005, permitted to 4,881 ft.
It was permitted by Occidental Permian Ltd. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 5 formation tops, including Rustler, Yates, Queen, Grayburg.
Its lease has reported 4.93M barrels of oil and 1.58M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 87 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.
Wells nearby
Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.

Well logs
1 log loaded from the RRC's log index, the latest received Feb 22, 2007. Cased hole, Gamma ray, Neutron. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
