Derrick #1B (API 42-237-39571) is a well in Jack County operated by Petrobal Omega 1 LLC, completed October 28, 2012.

The RRC has issued one drilling permit (amended once), issued May 23, 2012, permitted to 8,000 ft.

It was permitted by Veritas Energy, LLC and has since transferred to Petrobal Omega 1 LLC on the wellbore schedule.

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

Its 2 leases have reported 14.5K barrels of oil and 488K mcf of gas since October 2012, 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.
