Marathon-University 4 #2 (API 42-003-37770) is a well in Andrews County operated by Vin Fisher Operating Inc., completed January 18, 1996 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 11, 1995, permitted to 4,480 ft.
It was permitted by Rust Oil Corp. and has since transferred to Vin Fisher Operating Inc. on the wellbore schedule.
Completion filings report one formation top, including Yates.
Its lease has reported 7.86K barrels of oil and 9.22K mcf of gas since September 1994, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
