Wragg #1 (API 42-503-32620) is a well in Young County operated by Erwin Operating, completed January 19, 1981.

The RRC has issued one drilling permit, issued December 27, 1977, permitted to 4,900 ft.

It was permitted by Tex-Enex, Inc. and has since transferred to Erwin Operating on the wellbore schedule.

Completion filings report 4 formation tops, including Caddo, Marble Falls, Barnett, Mississippian.

Its 2 leases have reported 7.97K barrels of oil and 27.8K mcf of gas since January 1993, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
