Napper #18 (API 42-115-32189) is a plugged well in Dawson County, plugged April 28, 1995, last operated by Libertad Operating LLC.

The RRC has issued one drilling permit, issued April 4, 1985, permitted to 7,850 ft.

It was permitted by Bta Oil Producers and has since transferred to Libertad Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including San Andres, U. Spraberry, M. Spraberry, L. Spraberry.

Its lease has reported 88.8K barrels of oil and 17.9K mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
