Simpson #4 (API 42-269-32253) is a well in King County operated by Salida Exploration LLC, completed March 6, 2001 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued January 22, 1997, permitted to 3,500 ft.

It was permitted by Nosivad Oil, Inc. and has since transferred to Salida Exploration LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Dothan Lime, Stockwethel Lime, Stockwether Lime, Tannehill.

Its lease has reported 671K barrels of oil since December 1995, last reporting in July 2026. The lease carries 7 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 45K barrels injected in the 12 months reported through April 2026.

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