Simmons 72 #5 (API 42-435-35449) is a well in Sutton County operated by Upp Operating LLC, completed May 27, 2001 and listed as swr-10-well on the RRC schedule.

The RRC has issued one drilling permit, issued April 3, 2001, permitted to 7,990 ft.

It was permitted by Dreyfus, Louis Natural Gas Corp 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 604 barrels of oil and 352K mcf of gas since May 2001, last reporting volume in April 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.
