Swenson 4 Unit #1 (API 42-429-36023) is a well in Stephens County operated by Petex, completed October 1, 2003 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued August 28, 2003, permitted to 4,200 ft.

It was permitted by Mcclymond, Ltd. and has since transferred to Petex on the wellbore schedule.

Completion filings report 3 formation tops, including 1st Conglomerate, 2nd Conglomerate, Duffer.

Its 2 leases have reported 5.3K barrels of oil and 66.6K mcf of gas since October 2003, last reporting volume in April 2026. The leases carry 2 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.

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.
