Lee County · Giddings (Austin Chalk-3) field · Horizontal · Sidetrack
Koehler Unit #2ST (API 42-287-31616) is a horizontal well in Lee County operated by Redbud E & P Inc., completed June 14, 1990.
The RRC has issued 3 drilling permits (amended twice) between 1984 and 2011, permitted to 9,500 ft.
It was permitted by Impetro Operating LLC and has since transferred to Redbud E & P Inc. on the wellbore schedule.
Completion filings report 6 formation tops, including Navarro, Pecan Gap, Austin Chalk, Eagle Ford.
Its lease has reported 201K barrels of oil and 508K 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.
