Calvin Fachorn Unit #1
Burleson County · Giddings (Austin Chalk-3) field · Vertical
Calvin Fachorn Unit #1 (API 42-051-31166) is a well in Burleson County operated by Anadarko E&P Company LP, completed November 17, 1984.
The RRC has issued 3 drilling permits between 1980 and 1984, permitted to 7,850 ft.
It was permitted by Champlin Petroleum CO. and has since transferred to Anadarko E&P Company LP on the wellbore schedule.
Its 2 leases have reported 364K barrels of oil and 1.11M mcf of gas since January 1993, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
