Concho County · Millersview W. (Camar Sd.) field · NO Production · Vertical
Dierschke #1 (API 42-095-32066) is a well in Concho County operated by Cazar Energy Inc, completed September 20, 2004 and listed as no production on the RRC schedule.
The RRC has issued one drilling permit, issued May 11, 2004, permitted to 3,300 ft.
It was permitted by Guffey, WM. R. and has since transferred to Cazar Energy Inc on the wellbore schedule.
Completion filings report 3 formation tops, including Cook Sd, L. Cross-Cut Sd, Camar Sd.
Its lease has reported 18.6K barrels of oil and 3.43K mcf of gas since September 2004, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
