Chalk G. O. -D- #25 (API 42-227-34435) is a plugged well in Howard County, plugged April 20, 1999, last operated by Conocophillips Company.
The RRC has issued one drilling permit, issued May 2, 1989, permitted to 3,300 ft.
It was permitted by Conoco Inc. and has since transferred to Conocophillips Company on the wellbore schedule.
Completion filings report 2 formation tops, including San Andres, Glorieta.
Its lease has reported 73.8K barrels of oil and 8.48K mcf of gas since January 1993, with no volume in the three years through April 2026. The lease carries 17 wells, so these are lease totals, not this well alone.
