Winkler County · Two Georges (Bone Spring) field · Horizontal
University 20 TG Unit #1H (API 42-495-33241) is a plugged horizontal well in Winkler County, plugged December 13, 2021, last operated by Pdeh LLC.
The RRC has issued one drilling permit (amended once), issued February 10, 2007, permitted to 14,000 ft.
It was permitted by Chesapeake Operating, Inc. and has since transferred to Pdeh LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Bspg 1, Bspg 3rd Lime, Bspg - 3 Sd.
Its 2 leases have reported 1.79M barrels of oil and 2.1M mcf of gas since May 2007, with no volume in the three years through April 2026. The leases carry 17 wells, so these are lease totals, not this well alone.

Well logs
6 logs loaded from the RRC's log index, the latest received Oct 24, 2008. Cased hole, Density, Neutron, Resistivity, Sonic. 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.
