Espada Unit #9Z
Bexar County · Monksfield (350 Sand) field · Vertical
Espada Unit #9Z (API 42-029-37796) is a plugged well in Bexar County, plugged August 4, 2004, last operated by Root Drilling Company.
The RRC has issued one drilling permit, issued April 2, 1987, permitted to 600 ft.
It was permitted by R.D. Oil Company and has since transferred to Root Drilling Company on the wellbore schedule.
Completion filings report one formation top, including Escondido.
Its lease has reported 6.85K barrels of oil and 50 mcf of gas since January 1993, last reporting in July 2026. The lease carries 68 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by R.D. Oil Company; the EWA schedule now lists a different operator.
