Blacktip 1-21 WRD Unit 1 #4H
Ward County · Phantom (Wolfcamp) field · Shut In · Horizontal
Blacktip 1-21 Wrd Unit 1 #4H (API 42-475-36519) is a horizontal well in Ward County operated by Crescent Energy Operating LLC, completed October 27, 2013 and listed as shut in on the RRC schedule, shut in October 1, 2013.
The RRC has issued one drilling permit (amended once), issued August 9, 2013, permitted to 11,459 ft.
It was permitted by Shell Western E&P and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Dlwr_gp, Avu_c, Wc_ss_w1.
Its lease has reported 415K barrels of oil and 655K mcf of gas since August 2010, last reporting volume in April 2026. The lease carries 3 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Oct 19, 2016. 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.
