Weatherby Ivy B. #1
Pecos County · Wolfbone (Trend Area) field · Shut In · Vertical
Weatherby Ivy B. #1 (API 42-371-05736) is a well in Pecos County operated by Xto Energy Inc., completed August 27, 1987 and listed as shut in on the RRC schedule, shut in May 1, 2019.
The RRC has issued 2 drilling permits between 1977 and 1981, permitted to 15,766 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Xto Energy Inc. on the wellbore schedule.
Completion filings report one formation top, including Wolfcamp.
Its 2 leases have reported 11.8K barrels of oil since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
