Tiger 1 #1 (API 42-329-43053) is a well in Midland County operated by Oxyrock Operating LLC, completed May 16, 2019 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued January 15, 2019, permitted to 11,370 ft.
It was permitted by Crownquest Operating, LLC and has since transferred to Oxyrock Operating LLC on the wellbore schedule.
Completion filings report 9 formation tops, including Yates, Grayburg, San Andres, Glorieta.
Its lease has reported 178K barrels of oil and 452K mcf of gas since May 2019, last reporting volume in August 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

"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.
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.
