University Block 9 #8 H (API 42-003-38335) is a horizontal well in Andrews County operated by Xto Energy Inc., completed November 12, 2000.

The RRC has issued 3 drilling permits (amended twice) between 1997 and 2000, permitted to 10,800 ft.

It was permitted by Cross Timbers Operating Company and has since transferred to Xto Energy Inc. on the wellbore schedule.

Completion filings report 5 formation tops, including San Andres, Wlfcmp, Wolfcamp, Pennsylvanian.

Its 3 leases have reported 13.2M barrels of oil and 21.5M mcf of gas since January 1993, last reporting in July 2026. The leases carry 157 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
