Tubb J. B. A/C 1 #143 (API 42-103-31882) is a permitted well in Crane County filed by Exxon Corp.; no completion report is on file yet.

The RRC has issued one drilling permit, issued June 2, 1978, permitted to 4,536 ft.

It was permitted by Exxon Corp. and has since transferred to Formentera Operations LLC on the wellbore schedule.

Completion filings report one formation top, including Judkins.

Its 2 leases have reported 175K barrels of oil and 4.75M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The leases carry 73 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.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
