Lee County · Giddings (Austin Chalk Gas) field · Horizontal · Sidetrack
Cleopatra I Unit #1RE (API 42-287-30524) is a horizontal well in Lee County operated by Humble Exploration CO. Inc., completed September 10, 1979.
The RRC has issued 2 drilling permits between 1979 and 1997, permitted to 10,200 ft.
It was permitted by Union Pacific Resources Company and has since transferred to Humble Exploration CO. Inc. on the wellbore schedule.
Completion filings report one formation top, including Austin Chalk.
Its lease has reported 180K barrels of oil and 2.13M mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
