Frio County · Pearsall (Austin Chalk) field · Shut In · Horizontal

The RRC has issued one drilling permit (amended once), issued June 27, 2008, permitted to 7,310 ft.
It was permitted by Texas American Resources Company and has since transferred to Trinity Operating (Usg) LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Chalk, Eagle Ford, Buda.
Its lease has reported 21.1K barrels of oil and 3.26K mcf of gas since July 2010, with no volume in the three years through August 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.

1 log loaded from the RRC's log index, the latest received Jun 22, 2011. 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.
