Clarkson Estate #5 (API 42-383-34136) is a plugged well in Reagan County, plugged June 6, 2017, last operated by Diamondback E&P LLC.

The RRC has issued one drilling permit, issued September 25, 1991, permitted to 8,250 ft.

It was permitted by Stephens, Autry C. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Spraberry, Lower Spraberrry, Dean, Wolfcamp.

Its 2 leases have reported 109K barrels of oil and 567K mcf of gas since January 1993, last reporting in July 2026. The leases carry 9 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.
