LA Salle County · Pearsall (Austin Chalk) field  · Horizontal

Hunter Q. O. Unit #4 (API 42-283-31359) is a plugged horizontal well in La Salle County, plugged June 10, 2016, last operated by Texas American Resources Company.

The RRC has issued one drilling permit, issued September 5, 1990, permitted to 11,500 ft.

It was permitted by Oryx Energy Company and has since transferred to Texas American Resources Company on the wellbore schedule.

Completion filings report 4 formation tops, including Wilcox, San Miguel, Anacacho, Austin Chalk.

Its lease has reported 193K barrels of oil and 339K mcf of gas since January 1993, last reporting in September 2016. The lease carries 3 wells, so these are lease totals, not this well alone.
