University 13 #6 (API 42-383-34881) is a well in Reagan County operated by Pioneer Natural Res. USA Inc., completed January 18, 1999.
The RRC has issued 2 drilling permits between 1997 and 1999, permitted to 11,500 ft.
It was permitted by Vista Resources, Inc. (A) and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.
Completion filings report 7 formation tops, including Yates, Seven Rivers, Queen, Grayburg.
Its 3 leases have reported 294K barrels of oil and 1M mcf of gas since January 1993, last reporting in July 2026. The leases carry 12 wells, so these are lease totals, not this well alone.
