Rocker-B 30a #1 (API 42-383-32995) is a plugged well in Reagan County, plugged September 9, 2022, last operated by Discovery Natural Resources LLC.
The RRC has issued one drilling permit, issued March 27, 1984, permitted to 7,300 ft.
It was permitted by Tiburon Petroleum Corporation and has since transferred to Discovery Natural Resources LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Spraberry, Joe Mills, Dean, Wolfcamp.
Its lease has reported 41.2K barrels of oil and 227K mcf of gas since January 1993, with no volume in the three years through April 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
