Calvert #2H (API 42-163-33513) is a horizontal well in Frio County operated by Blackbrush O & G LLC, completed November 13, 2011 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued August 24, 2011, permitted to 7,500 ft.

It was permitted by Blackbrush O & G, Inc. and has since transferred to Blackbrush O & G LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Austin Chalk, Eagle Ford, Buda.

Its lease has reported 94.1K barrels of oil and 2.01M mcf of gas since June 2011, last reporting in July 2026. The lease carries 3 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.
