Oconnor -D- #D 40 (API 42-391-32602) is a well in Refugio County operated by T-C Oil Company LLC, completed July 16, 2004 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued June 17, 2004, permitted to 4,697 ft.

It was permitted by T - C Oil Company and has since transferred to T-C Oil Company LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Lagarto, Miocene (undifferentiated), Catahoula, Greta.

Its lease has reported 1.32M barrels of oil and 5.82M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 25 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.
