Piloncillo #D 17HA (API 42-479-41812) is a horizontal well in Webb County operated by Tbm Catarina LLC, completed August 21, 2017 and listed as swr-10-well on the RRC schedule.
The RRC has issued one drilling permit (amended 3 times), issued April 11, 2012, permitted to 8,629 ft.
It was permitted by SN Operating, LLC and has since transferred to Tbm Catarina LLC on the wellbore schedule.
Completion filings report 8 formation tops, including Escondido, Olmos, San Miguel, Austin Chalk.
Its 2 leases have reported 106K barrels of oil and 2.01M mcf of gas since January 2013, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, 1 of it with a digital LAS file, the latest received Aug 1, 2019. 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.
