Schmoker Lambert Tabor Unit #1 (API 42-197-31110) is a well in Hardeman County operated by Cobra Oil & Gas Corporation, completed February 9, 1990 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued November 22, 1989, permitted to 8,350 ft.
It was permitted by Kadane Oil Company and has since transferred to Cobra Oil & Gas Corporation on the wellbore schedule.
Completion filings report 3 formation tops, including Canyon, Morrow, Mississippian.
Its lease has reported 917K barrels of oil and 21 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.
