Miller 312 #4 (API 42-033-31003) is a well in Borden County operated by HW Operating LLC, completed February 23, 1992 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued January 25, 1984, permitted to 9,000 ft.

It was permitted by Mitchell Energy Corporation and has since transferred to HW Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Yates, San Andres, Clear Fork, Strawn.

Its lease has reported 136K barrels of oil and 70K mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
