Davis C. S. A #4 (API 42-305-30212) is a well in Lynn County operated by Three Span Oil & Gas Inc., completed March 22, 2024 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued November 5, 1979, permitted to 4,550 ft.
It was permitted by M & H Oil CO. and has since transferred to Three Span Oil & Gas Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including San Andres, Glorieta, Productive Zone.
Its lease has reported 62K barrels of oil and 77.2K mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
