Harper A #635NH (API 42-235-35965) is a horizontal well in Irion County operated by Discovery Natural Resources LLC, completed July 10, 2016 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued September 25, 2014, permitted to 9,800 ft.

It was permitted by Fiml Natural Resources, LLC and has since transferred to Discovery Natural Resources LLC on the wellbore schedule.

Completion filings report 7 formation tops, including Grayburg, San Andres, Clear Fork, Spraberry.

Its lease has reported 405K barrels of oil and 2.09M mcf of gas since April 2013, last reporting in July 2026. The lease carries 4 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.
