Wragg #1 (API 42-503-33515) is a well in Young County operated by Erwin Operating, completed February 1, 1980 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued October 17, 1979, permitted to 4,800 ft.
It was permitted by Magnum Resources, Inc. and has since transferred to Erwin Operating on the wellbore schedule.
Completion filings report 6 formation tops, including Palo Pinto, Battram Sand, Strawn, Caddo.
Its lease has reported 7.97K barrels of oil and 27.8K 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.
