O Connor Dennis ET AL -L- #L 87 (API 42-391-32598) is a well in Refugio County operated by T-C Oil Company LLC, completed April 13, 2007.

The RRC has issued 2 drilling permits between 2004 and 2007, permitted to 4,900 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 5 formation tops, including Lagarto, Lagato, Miocene (undifferentiated), Catahoula.

Its 2 leases have reported 3.49M barrels of oil and 48.5M mcf of gas since January 1993, last reporting in July 2026. The leases carry 82 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 108K barrels injected in the 12 months reported through October 2025.

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