Sau Mariner 7-4b #4 (API 42-383-35522) is a permitted well in Reagan County filed by Mariner Energy, Inc.; no completion report is on file yet.

The RRC has issued one drilling permit, issued February 23, 2005, permitted to 8,175 ft.

It was permitted by Mariner Energy, Inc. and has since transferred to Apache Corporation on the wellbore schedule.

Completion filings report 2 formation tops, including Spraberry, Dean.

Its 2 leases have reported 110K barrels of oil and 767K mcf of gas since September 2003, with no volume in the three years through April 2026. The leases carry 5 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.
