Munson #1201 (API 42-235-34965) is a plugged well in Irion County, plugged November 2, 2022, last operated by Sem Operating Company LLC.
The RRC has issued one drilling permit (amended once), issued January 27, 2012, permitted to 9,600 ft.
It was permitted by Eog Resources, Inc. and has since transferred to Sem Operating Company LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Wolfcamp, Ellenburger.
Its lease has reported 983K barrels of oil and 17.3M mcf of gas since March 2011, last reporting volume in April 2026. The lease carries 9 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Jul 13, 2015. Density, Neutron, Resistivity. 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.
