WELL · 42-357-31445 · DISTRICT 10
Gramstorff #4
Ochiltree County · Booker N. (Morrow Upper) field · Vertical
Gramstorff #4 (API 42-357-31445) is a well in Ochiltree County operated by Vintage Petroleum Inc., completed December 13, 1983.
The RRC has issued one drilling permit, issued September 19, 1983, permitted to 8,450 ft.
It was permitted by L & M Oil CO. and has since transferred to Vintage Petroleum Inc. on the wellbore schedule.
Completion filings report 7 formation tops, including Brown Dolomite, Pennsylvanian, Hebner, Douglas.
Its 2 leases have reported 2.12M barrels of oil and 306K mcf of gas since January 1993, last reporting in July 2026. The leases carry 18 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
