Millar L. H. Etal #4324 (API 42-371-36534) is a well in Pecos County operated by Olsen Energy Inc., completed October 24, 1995 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued June 19, 1995, permitted to 4,592 ft.
It was permitted by Chevron U. S. A. Inc. and has since transferred to Olsen Energy Inc. on the wellbore schedule.
Completion filings report 10 formation tops, including Tansill, Yates, Queen, San Andres.
Its lease has reported 724K barrels of oil and 51.8K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 16 wells, so these are lease totals, not this well alone.
