Texas-Osage #1
Zavala County · Lorenzo (Austin Chalk) field · Producing · Horizontal
Texas-Osage #1 (API 42-507-32738) is a horizontal well in Zavala County operated by Atlas Operating LLC, completed October 26, 2009 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued January 29, 2009, permitted to 7,500 ft.
It was permitted by Sanchez Oil & Gas Corporation and has since transferred to Atlas Operating LLC on the wellbore schedule.
Completion filings report 6 formation tops, including San Miguel, Austin Chalk, Eagle Ford, Buda.
Its lease has reported 124K barrels of oil and 58.1K mcf of gas since October 2009, last reporting volume in March 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Sep 30, 2013. Density, Neutron, 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.
