Mrs. T. B. Roberts R/A -A- #31 (API 42-135-34426) is a permitted well in Ector County filed by Amoco Production Company; no completion report is on file yet.
The RRC has issued one drilling permit, issued December 23, 1983, permitted to 10,543 ft.
It was permitted by Amoco Production Company and has since transferred to Formentera Operations LLC on the wellbore schedule.
Completion filings report one formation top, including Pennsylvanian.
Its lease has reported 148K barrels of oil and 1.21M mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
