Degan Sand Unit #12W (API 42-181-30977) is a well in Grayson County operated by Felderhoff Production Company, completed September 26, 1983 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued July 29, 1983, permitted to 4,600 ft.
It was permitted by Gulf Oil Corp. and has since transferred to Felderhoff Production Company on the wellbore schedule.
Completion filings report 4 formation tops, including Goodland, Red Strawn, Base Gray Strawn, Degan.
Its lease has reported 461K barrels of oil and 465 mcf of gas since January 1993, last reporting in July 2026. The lease carries 14 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 4.38K barrels injected in the 12 months reported through September 2025.
