River Ranch -A-/Williams State U #2 (API 42-391-32880) is a well in Refugio County operated by T-C Oil Company LLC, completed June 5, 2009 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued November 13, 2008, permitted to 5,600 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, Oakville, Catahoula, Greta.

Its lease has reported 1.99M barrels of oil and 509K mcf of gas since September 2008, last reporting volume in April 2026. The lease carries 12 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.

Well logs

2 logs loaded from the RRC's log index, the latest received Jun 13, 2012. Density, Neutron, Resistivity. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
