Coleman -D- #D-4 (API 42-335-31579) is a well in Mitchell County operated by Tnch LLC, completed December 28, 1979 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued December 3, 1979, permitted to 3,200 ft.
It was permitted by Barnes-Pomeroy Oil Company and has since transferred to Tnch LLC on the wellbore schedule.
Completion filings report one formation top, including Clear Fork.
Its lease has reported 112K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 23.4K barrels injected in the 12 months reported through January 2026.
