Andrews County · University Block 9 (Wolfcamp) field · Vertical
University Blk.9 /Wolfcamp/ Unit #1CB (API 42-003-00686) is a plugged well in Andrews County, plugged December 6, 2007, last operated by Xto Energy Inc..
The RRC has issued one drilling permit, issued December 19, 2000, permitted to 8,847 ft.
It was permitted by Cross Timbers Operating Company and has since transferred to Xto Energy Inc. on the wellbore schedule.
Its 2 leases have reported 7.4M barrels of oil and 15.1M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 136 wells, so these are lease totals, not this well alone.
