University Block 9 #8H (API 42-003-38384) is a horizontal well in Andrews County operated by Xto Energy Inc., completed June 4, 2024 and listed as injection on the RRC schedule.

The RRC has issued 5 drilling permits between 1998 and 2006, permitted to 10,900 ft.

Completion filings report 8 formation tops, including Grayburg, San Andres, Wolfcamp, Pennsylvanian.

Its 3 leases have reported 13.7M barrels of oil and 21.9M mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 159 wells, so these are lease totals, not this well alone.
