Weir J. C. 12 #2 (API 42-461-33289) is a well in Upton County operated by Petroplex Energy Inc., completed October 10, 2000.
The RRC has issued 2 drilling permits (amended once) between 1992 and 2011, permitted to 10,300 ft.
It was permitted by Chevron U. S. A. Inc. and has since transferred to Petroplex Energy Inc. on the wellbore schedule.
Completion filings report 8 formation tops, including Rustler, Yates, Queen, Mcelroy.
Its 2 leases have reported 594K barrels of oil and 1.77M mcf of gas since January 1993, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
