Hamilton #1A (API 42-237-38780) is a well in Jack County operated by Extech Operating LLC, completed September 10, 2004.

The RRC has issued one drilling permit, issued June 7, 2004, permitted to 6,500 ft.

It was permitted by Gonzenbach, Glen D and has since transferred to Extech Operating LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Caddo, Atoka, Marble Falls.

Its 2 leases have reported 5.08K barrels of oil and 521K mcf of gas since September 2004, 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.
