May Tom #23
Gaines County · G-M-K South (San Andres) field · Injection · Vertical
May Tom #23 (API 42-165-31319) is a well in Gaines County operated by Hilcorp Energy Company, completed January 2, 2023 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued January 23, 1978, permitted to 5,515 ft.
It was permitted by Mobil Oil Corporation and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 3 formation tops, including Yates, Grayburg, San Andres.
Its lease has reported 4.77M barrels of oil and 9.51M mcf of gas since the record begins in January 1993, last reporting volume in April 2026. The lease carries 33 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.

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.
