Rocker B -M- #48 (API 42-383-34883) is a well in Reagan County operated by Discovery Natural Resources LLC, completed July 23, 1998.

The RRC has issued one drilling permit, issued November 26, 1997, 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.

Completion filings report 3 formation tops, including Santa Rose, Spraberry, Dean.

Its 2 leases have reported 8.58M barrels of oil and 60.4M mcf of gas since January 1993, last reporting in July 2026. The leases carry 179 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
