Ribardo-Ribardo Unit #3 (API 42-041-31497) is a plugged horizontal well in Brazos County, plugged June 28, 2019, last operated by Endeavor Energy Resources L.P..
The RRC has issued one drilling permit, issued April 19, 1991, permitted to 13,000 ft.
It was permitted by Union Pacific Resources Company and has since transferred to Endeavor Energy Resources L.P. on the wellbore schedule.
Completion filings report 6 formation tops, including Midway, Navarro, Pecan Gap, Austin Chalk.
Its lease has reported 10.8K barrels of oil and 15.9K mcf of gas since January 1993, last reporting in March 2020. The lease carries 3 wells, so these are lease totals, not this well alone.
