The RRC has issued 3 drilling permits (amended 3 times) between 1999 and 2004, permitted to 6,725 ft.
It was permitted by Winn Exploration CO., Inc. and has since transferred to Griffin Resources LLC on the wellbore schedule.

Its 4 leases have reported 299K barrels of oil and 3.88M mcf of gas since July 1995, last reporting in July 2026. The leases carry 6 wells, so these are lease totals, not this well alone.
