McMullen County · Big Mule (5500 Sand) field · Vertical
South Texas Syndicate #3020 (API 42-311-31873) is a well in Mcmullen County operated by Kaler Energy Corp., completed September 6, 1983.
The RRC has issued one drilling permit, issued July 7, 1983, permitted to 6,010 ft.
It was permitted by Hawn Bros-Chapman Oil-La Fete and has since transferred to Kaler Energy Corp. on the wellbore schedule.
Its 2 leases have reported 57.4K barrels of oil and 345 mcf of gas since January 1993, last reporting in July 2026. The leases carry 24 wells, so these are lease totals, not this well alone.
