Kathryn #4813 (API 42-461-35430) is a well in Upton County operated by SM Energy Company, completed September 25, 2020 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued September 20, 2007, permitted to 11,000 ft.

It was permitted by ST. Mary Land & Exploration CO. and has since transferred to SM Energy Company on the wellbore schedule.

Completion filings report 4 formation tops, including San Andres, Clear Fork, Spraberry, Wolfcamp.

Its lease has reported 737K barrels of oil and 2.28M mcf of gas since February 2005, last reporting in July 2026. The lease carries 15 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.
