Shedrock Walter #1 (API 42-493-31856) is a plugged well in Wilson County, plugged March 9, 2026, last operated by Petrosaurus Inc..

The RRC has issued one drilling permit, issued January 10, 1986, permitted to 1,800 ft.

It was permitted by Seaco Production and has since transferred to Petrosaurus Inc. on the wellbore schedule.

Completion filings report one formation top, including Navarro.

Its lease has reported 8.44K barrels of oil and 95 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.

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