E. Zimmerhanzel Oil Unit #1 H (API 42-149-32443) is a plugged horizontal well in Fayette County, plugged January 29, 1996, last operated by Coastal Oil & Gas Corporation.

The RRC has issued 2 drilling permits between 1991 and 2009, permitted to 13,000 ft.

It was permitted by Lama Energy, L.L.C. and has since transferred to Coastal Oil & Gas Corporation on the wellbore schedule.

Completion filings report 5 formation tops, including Midway, Navarro, Taylor, Pecan Gap.

Its 2 leases have reported 121K barrels of oil and 248K mcf of gas since January 1993, 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.
