Brown County · Brown County Regular field · Producing · Vertical

Guthrie R.C. #1 (API 42-049-35981) is a well in Brown County operated by M.K.B. Energy Corp, completed September 14, 2010 and listed as producing on the RRC schedule, shut in June 1, 2026.

The RRC has issued one drilling permit, issued July 13, 2010, permitted to 1,593 ft.

It was permitted by Ziegler-Peru, Inc. and has since transferred to M.K.B. Energy Corp on the wellbore schedule.

Completion filings report 3 formation tops, including Caddo, Bend, Marble Falls.

Its 2 leases have reported 27.4K barrels of oil and 687 mcf of gas since January 1993, last reporting volume in April 2026. The leases carry 90 wells, so these are lease totals, not this well alone.

Well logs

1 log loaded from the RRC's log index, the latest received Jul 18, 2011. 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.
