Scurry County · Sharon Ridge (Clear Fork) field · Producing · Vertical
Thomas A #21 (API 42-415-31866) is a well in Scurry County operated by Green Light Operating LLC., completed July 28, 1981 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued March 3, 1981, permitted to 3,600 ft.
It was permitted by Ellpen, Inc. and has since transferred to Green Light Operating LLC. on the wellbore schedule.
Its lease has reported 34.1K barrels of oil and 122 mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
Operator of record
