Midland County · Brazos (San Andres) field  · Horizontal

Eugene #1 (API 42-329-31123) is a horizontal well in Midland County operated by Flat Top Operating LLC, completed March 11, 1983.

The RRC has issued 2 drilling permits between 1982 and 2004, permitted to 6,000 ft.

It was permitted by Prime Operating Company and has since transferred to Flat Top Operating LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Queen, Grayburg, San Andres.

Its lease has reported 249K barrels of oil and 19 mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 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.
