Chalk G. O.-G- #56 (API 42-227-37055) is a well in Howard County operated by Citation Oil & Gas Corp., completed February 19, 2013 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued June 25, 2012, permitted to 4,307 ft.
It was permitted by Conocophillips Company and has since transferred to Citation Oil & Gas Corp. on the wellbore schedule.
Completion filings report 3 formation tops, including Yates, San Andres, Tubb.
Its lease has reported 496K barrels of oil and 140K mcf of gas since December 2011, last reporting in July 2026. The lease carries 38 wells, so these are lease totals, not this well alone.
