Rudd Gas Unit 2 #4 (API 42-203-31842) is a well in Harrison County operated by Sonat Exploration Company-Mcr, completed March 8, 1990.
The RRC has issued 3 drilling permits (amended twice) between 1989 and 2004, permitted to 9,505 ft.
It was permitted by Comstock Oil & Gas, Inc. and has since transferred to Sonat Exploration Company-Mcr on the wellbore schedule.
Completion filings report 7 formation tops, including Ferry Lake, Base Mass. Anhydrite, Rodessa, James Lime.
Its 3 leases have reported 18.4K barrels of oil and 770K mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
