Dorcus #4201 (API 42-461-34600) is a plugged well in Upton County, plugged August 11, 2025, last operated by SM Energy Company.

The RRC has issued one drilling permit (amended once), issued August 3, 2004, permitted to 10,800 ft.

It was permitted by Henry Petroleum LP and has since transferred to SM Energy Company on the wellbore schedule.

Completion filings report 5 formation tops, including San Andres, Clear Fork, Spraberry, Dean.

Its lease has reported 3.88M barrels of oil and 15.2M mcf of gas since November 2003, last reporting volume in April 2026. The lease carries 53 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.

Well logs

1 log loaded from the RRC's log index, the latest received Jul 28, 2008. Neutron. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
