Moss Paul South(Canyon 8790)Unit #199 (API 42-135-36434) is a well in Ector County operated by R3 Operating Corporation, completed June 11, 1991 and listed as partial plug on the RRC schedule.
The RRC has issued 2 drilling permits between 1991 and 2016, permitted to 9,200 ft.
It was permitted by White Rock Oil & Gas, LLC and has since transferred to R3 Operating Corporation on the wellbore schedule.
Completion filings report 13 formation tops, including Rustler, Seven Rivers, Canyon, Grayburg.
Its 2 leases have reported 4.33M barrels of oil and 2.21M mcf of gas since January 1993, last reporting in July 2026. The leases carry 186 wells, so these are lease totals, not this well alone.
