WELL · 42-383-30724 · DISTRICT 7
University Lease #93
Reagan County · Big Lake field · Vertical
University Lease #93 (API 42-383-30724) is a well in Reagan County operated by O Ryan Oil And Gas, completed May 29, 1976.
The RRC has issued one drilling permit, issued October 19, 1979, permitted to 8,000 ft.
It was permitted by Conoco Inc. and has since transferred to O Ryan Oil And Gas on the wellbore schedule.
Completion filings report one formation top, including Spraberry.
Its 2 leases have reported 4.85M barrels of oil and 2.24M mcf of gas since January 1993, last reporting in July 2026. The leases carry 127 wells, so these are lease totals, not this well alone.
