Chalk Mary #62
Howard County · Howard-Glasscock (Glorieta) field · Vertical
Chalk Mary #62 (API 42-227-33088) is a plugged well in Howard County, plugged May 3, 1996, last operated by Conocophillips Company.
The RRC has issued one drilling permit, issued July 28, 1983, permitted to 3,100 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Conocophillips Company on the wellbore schedule.
Its lease has reported 642K barrels of oil and 188K mcf of gas since the record begins in January 1993, with no volume in the three years through August 2026. The lease carries 29 wells, so these are lease totals, not this well alone.
