Graham 48 #1 (API 42-329-31213) is a plugged well in Midland County, plugged May 21, 2009, last operated by Diamondback E&P LLC.
The RRC has issued one drilling permit, issued September 15, 1983, permitted to 9,100 ft.
It was permitted by Coseka Resources (U.S.A.) Ltd. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Its lease has reported 147K barrels of oil and 244K mcf of gas since January 1993, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
