Block 31 Unit #T 9N (API 42-103-33864) is a well in Crane County operated by Oxy USA Eor LLC, completed November 18, 1988.

The RRC has issued 2 drilling permits (amended once) between 1988 and 2018, permitted to 9,500 ft.

It was permitted by Oxy USA Inc. and has since transferred to Oxy USA Eor LLC on the wellbore schedule.

Completion filings report 11 formation tops, including Barnett, Mississippian, Woodford, Devonian.

Its 2 leases have reported 15.7M barrels of oil and 974M mcf of gas since January 1993, last reporting in July 2026. The leases carry 358 wells, so these are lease totals, not this well alone.
