Cobb T. B. #42 (API 42-179-30755) is a well in Gray County operated by Sanchez Production LLC, completed October 29, 1980 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued February 8, 1980, permitted to 3,500 ft.
It was permitted by Amoco Production Company and has since transferred to Sanchez Production LLC on the wellbore schedule.
Completion filings report one formation top, including Dolomite.
Its lease has reported 62.5K barrels of oil and 111K mcf of gas since January 1993, last reporting in July 2026. The lease carries 30 wells, so these are lease totals, not this well alone.
