Cornerstone #2 (API 42-157-31708) is a plugged well in Fort Bend County, plugged October 20, 2006, last operated by Mckenzie Production Company.

The RRC has issued one drilling permit, issued June 30, 1986, permitted to 7,834 ft.

It was permitted by Irish O&G CO./Brown & Mckenzie and has since transferred to Mckenzie Production Company on the wellbore schedule.

Completion filings report 4 formation tops, including Frio, Vicksburg, Yegua, Clodine Sand (Yegua).

Its lease has reported 64.9K barrels of oil and 4.37K mcf of gas since January 1993, last reporting in April 2007. The lease carries 2 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
