Tom A #1 (API 42-317-40378) is a well in Martin County operated by Diamondback E&P LLC, completed April 26, 2016 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued January 27, 2016, permitted to 12,000 ft.

It was permitted by R K Petroleum Corp. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Santa Rosa, Yates, Grayburg, San Andres.

Its lease has reported 76.8K barrels of oil and 225K mcf of gas since April 2016, 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.
