Edwards Clara #11 (API 42-135-39890) is a well in Ector County operated by Diamondback E&P LLC, completed December 29, 2009 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued July 9, 2009, permitted to 10,202 ft.

It was permitted by Devon Energy Production CO, L.P. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 4 formation tops, including San Andres, Clear Fork, Spraberry, Wolfcamp.

Its lease has reported 1.1M barrels of oil and 4.22M mcf of gas since December 2009, last reporting in July 2026. The lease carries 6 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.
