Dyer J. F. #20 (API 42-417-32433) is a well in Shackelford County operated by Centex Development, completed February 4, 1978.
The RRC has issued one drilling permit, issued November 17, 1977, permitted to 1,000 ft.
It was permitted by Rogers Drilling CO. and has since transferred to Centex Development on the wellbore schedule.
Its 2 leases have reported 6.89K barrels of oil and 52 mcf of gas since January 1993, last reporting in July 2026. The leases carry 37 wells, so these are lease totals, not this well alone.
