Pecos County · Wolfbone (Trend Area) field · Producing · Horizontal
Mdj Caldwell #N 21H (API 42-371-39245) is a horizontal well in Pecos County operated by Crescent Energy Operating LLC, completed March 23, 2017 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued August 21, 2014, permitted to 10,639 ft.
It was permitted by Oxy USA Wtp LP and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.
Completion filings report 10 formation tops, including Glorieta, Grayburg, O'Brien, Queen.
Its lease has reported 1.79M barrels of oil and 9.88M mcf of gas since May 2015, last reporting volume in April 2026. The lease carries 10 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Mar 9, 2020. While drilling (MWD). 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.
