L. S. Mcclaugherty GU #1 (API 42-311-30867) is a well in Mcmullen County operated by Varas Energy Operating Company, completed October 1, 1999 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits (amended once) between 1977 and 1999, permitted to 12,500 ft.
It was permitted by Swift Energy Company and has since transferred to Varas Energy Operating Company on the wellbore schedule.
Completion filings report 9 formation tops, including Sparta, Queen City, Carrizo, Wilcox.
Its 2 leases have reported 24.6K barrels of oil and 657K mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
