Webb Branch Unit #1 (API 42-051-33609) is a horizontal well in Burleson County operated by Magnolia Oil & Gas Operating LLC, completed February 21, 2003 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued January 16, 2002, permitted to 10,277 ft.

It was permitted by Rme Petroleum Company and has since transferred to Magnolia Oil & Gas Operating LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Austin Chalk, Lower Cretaceous, Buda.

Its 2 leases have reported 269K barrels of oil and 218K mcf of gas since March 2002, last reporting 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.
