University 7-28 B #3 (API 42-317-37045) is a plugged well in Martin County, plugged July 30, 2018, last operated by Diamondback E&P LLC.

The RRC has issued one drilling permit, issued July 20, 2011, permitted to 12,000 ft.

It was permitted by Chesapeake Operating, Inc. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 7 formation tops, including Clear Fork, Upr Spraberry, Lwr Spraberry, Dean.

Its lease has reported 291K barrels of oil and 759K mcf of gas since September 2008, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
