Rock Hollow #3 (API 42-235-31220) is a plugged well in Irion County, plugged October 29, 2014, last operated by Discovery Natural Resources LLC.
The RRC has issued one drilling permit, issued January 5, 1978, permitted to 7,600 ft.
It was permitted by Nrm Petroleum Corp. and has since transferred to Discovery Natural Resources LLC on the wellbore schedule.

Its 2 leases have reported 3.09M barrels of oil and 35.4M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 67 wells, so these are lease totals, not this well alone.
