UL 20 S Bucktail #1H (API 42-495-33544) is a horizontal well in Winkler County operated by Pdeh LLC, completed July 13, 2014 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 31, 2013, permitted to 11,658 ft.
It was permitted by Shell Western E&P and has since transferred to Pdeh LLC on the wellbore schedule.
Completion filings report 14 formation tops, including Delaware, Brushy Canyon, Bone Spring, Wolfcamp.
Its 3 leases have reported 6.15M barrels of oil and 7.52M mcf of gas since June 2013, last reporting volume in August 2026. The leases carry 34 wells, so these are lease totals, not this well alone.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.
Wells nearby
Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.

Well logs
1 log loaded from the RRC's log index, 1 of it with a digital LAS file, the latest received Mar 1, 2017. Gamma ray. 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.
