Rocker B #18
Reagan County · Spraberry (Trend Area) field · Vertical
Rocker B #18 (API 42-383-33393) is a plugged well in Reagan County, plugged April 16, 2014, last operated by Pioneer Natural Res. USA Inc..
The RRC has issued one drilling permit, issued February 27, 1985, permitted to 7,400 ft.
It was permitted by Cox, John L. and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including Santa Rosa, Spraberry, Dean.
Its 2 leases have reported 13.6M barrels of oil and 110M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 277 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Cox, John L.; the EWA schedule now lists a different operator.
