Blue Estate #11 (API 42-495-31059) is a well in Winkler County operated by Formentera Operations LLC, completed November 6, 1986 and listed as producing on the RRC schedule.

The RRC has issued 4 drilling permits between 1979 and 1986, permitted to 11,472 ft.

It was permitted by Amoco Production CO.-Andrews and has since transferred to Formentera Operations LLC on the wellbore schedule.

Completion filings report 8 formation tops, including Santa Rosa, Wichita-Albany, Wolfcamp, Devonian.

Its lease has reported 585K barrels of oil and 6.27M mcf of gas since January 1993, last reporting in July 2026. The lease carries 11 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.
