Zavala County · Ammann (Buda) field · Shut IN  · Horizontal

Jmh Zav #1HB (API 42-507-33209) is a horizontal well in Zavala County operated by Buffco Production Inc., completed February 10, 2015 and listed as shut in on the RRC schedule, shut in June 1, 2021.

The RRC has issued one drilling permit (amended once), issued November 4, 2014, permitted to 6,750 ft.

It was permitted by Exco Operating Company, LP and has since transferred to Buffco Production Inc. on the wellbore schedule.

Completion filings report 6 formation tops, including Escondido, Olmos, Anacacho, Austin Chalk.

Its lease has reported 208K barrels of oil and 602K mcf of gas since January 2015, last reporting in July 2026. The lease carries 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.
