Thompson #122
Zavala County · Pearsall (Austin Chalk) field · Vertical
Thompson #122 (API 42-507-30921) is a plugged well in Zavala County, plugged November 13, 2004, last operated by Ineos USA Oil & Gas LLC.
The RRC has issued one drilling permit, issued September 29, 1977, permitted to 7,500 ft.
It was permitted by Champlin Petroleum CO. and has since transferred to Ineos USA Oil & Gas LLC on the wellbore schedule.
Its lease has reported 294K barrels of oil and 718K mcf of gas since January 1993, with no volume in the three years through April 2026. The lease carries 28 wells, so these are lease totals, not this well alone.
