Machemehl #1
Burleson County · Giddings (Austin Chalk Gas) field · Horizontal
Machemehl #1 (API 42-051-33111) is a horizontal well in Burleson County operated by Enervest Operating L.L.C., completed November 14, 2002.
The RRC has issued one drilling permit, issued September 6, 1990, permitted to 8,450 ft.
It was permitted by Txo Production Corp. and has since transferred to Enervest Operating L.L.C. on the wellbore schedule.
Completion filings report 2 formation tops, including Wilcox, Austin Chalk.
Its 3 leases have reported 26.6K barrels of oil and 1.05M 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.
