Robuck M. #10 (API 42-055-34448) is a well in Caldwell County operated by Hidden Oaks Oil Company LLC, completed August 18, 1989 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued June 30, 1989, permitted to 2,400 ft.
It was permitted by Spiller, J.A. and has since transferred to Hidden Oaks Oil Company LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Pecan Gap, Austin Chalk, Eagle Ford, Buda.
Its lease has reported 97.5K barrels of oil and 219K mcf of gas since January 1993, last reporting in July 2026. The lease carries 14 wells, so these are lease totals, not this well alone.
