Zachry E.B. #6 (API 42-505-32157) is a well in Zapata County operated by Hilcorp Energy Company, completed July 1, 1999 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 27, 1985, permitted to 10,200 ft.
It was permitted by Mobil Producing TX. & N.M. Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 2 formation tops, including Lobo 8900, Lobo.
Its 2 leases have reported 1.99M 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.
