Hill-Mayer RR #103 (API 42-413-32359) is a well in Schleicher County operated by Upp Operating LLC, completed August 2, 2006 and listed as swr-10-well on the RRC schedule.

The RRC has issued one drilling permit, issued April 20, 2006, permitted to 8,600 ft.

It was permitted by Dominion Oklahoma Texas E&P, Inc and has since transferred to Upp Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Base Cretaceous (marker), Wolfcamp, Canyon, Strawn.

Its 2 leases have reported 644 barrels of oil and 330K mcf of gas since June 2006, last reporting volume in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
