Harper Devonian Unit #710 (API 42-135-41824) is a well in Ector County operated by Oxy USA Wtp Eor LLC, completed September 3, 2012 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued May 9, 2012, permitted to 11,000 ft.

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

Completion filings report one formation top, including Devonian.

Its lease has reported 2.33M barrels of oil and 16M mcf of gas since January 1993, last reporting in July 2026. The lease carries 42 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.
