Block 31 Unit #Q 16 (API 42-103-33942) is a plugged well in Crane County, plugged October 9, 2018, last operated by Oxy USA Eor LLC.

The RRC has issued 2 drilling permits between 1989 and 2013, 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 14 formation tops, including Grayburg, Clear Fork, Barnett, Mississippian.

Its lease has reported 15.2M barrels of oil and 971M mcf of gas since January 1993, last reporting in July 2026. The lease carries 330 wells, so these are lease totals, not this well alone.
