Millar L. H. ET AL #3928 (API 42-371-36560) is a permitted well in Pecos County filed by Chevron U. S. A. Inc.; no completion report is on file yet.

The RRC has issued one drilling permit, issued November 1, 1995, permitted to 4,480 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 4 formation tops, including San Andres, Wichita-Albany, Wolfcamp, Granite Wash.

Its 2 leases have reported 41.7K barrels of oil and 2M mcf of gas since January 1993, last reporting in July 2026. The leases carry 6 wells, so these are lease totals, not this well alone.
