XBC Giddings Estate #20
Upton County · Spraberry (Trend Area) field · Water Supply · Vertical
Xbc Giddings Estate #20 (API 42-461-32640) is a well in Upton County operated by Pioneer Natural Res. USA Inc., completed April 9, 2011 and listed as water supply on the RRC schedule, shut in February 1, 2026.
The RRC has issued one drilling permit, issued June 8, 1987, permitted to 8,280 ft.
It was permitted by Exxon Corp. and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.
Completion filings report 2 formation tops, including Grayburg, Spraberry.
Its 3 leases have reported 45.7M barrels of oil and 156M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 559 wells, so these are lease totals, not this well alone.
