Alvey Estate #28 (API 42-059-36721) is a well in Callahan County operated by Cyber Enviro-Tech Inc, completed February 21, 2009 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued April 26, 2007, permitted to 1,000 ft.
It was permitted by Diamond S Masada LLC and has since transferred to Cyber Enviro-Tech Inc on the wellbore schedule.
Completion filings report 3 formation tops, including Frye, Tannehill, Slc/Ls.
Its lease has reported 25.3K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 33 wells, so these are lease totals, not this well alone.
