Rocker B. -T- #19 (API 42-383-33085) is a plugged well in Reagan County, plugged November 24, 2025, last operated by Discovery Natural Resources LLC.
The RRC has issued one drilling permit, issued May 31, 1984, permitted to 7,200 ft.
It was permitted by Cox, John L. and has since transferred to Discovery Natural Resources LLC on the wellbore schedule.

Its lease has reported 195K barrels of oil and 1.65M mcf of gas since January 1993, last reporting volume in June 2024. The lease carries 18 wells, so these are lease totals, not this well alone.
