Chalk G. O. -B- #20 (API 42-227-34587) is a plugged well in Howard County, plugged May 16, 1996, last operated by Conocophillips Company.

The RRC has issued one drilling permit, issued September 10, 1990, permitted to 3,200 ft.

It was permitted by Conoco Inc. and has since transferred to Conocophillips Company on the wellbore schedule.

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

Its lease has reported 39K barrels of oil and 6.76K mcf of gas since January 1993, last reporting in September 2016. The lease carries 9 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.
