Mcc #8 (API 42-329-36103) is a plugged well in Midland County, plugged August 5, 2020, last operated by Cog Operating LLC.

The RRC has issued 2 drilling permits between 2008 and 2010, permitted to 12,000 ft.

It was permitted by Patriot Resources, Inc. and has since transferred to Cog Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including San Andres, Glorieta, Spraberry, Dean.

Its lease has reported 428K barrels of oil and 951K mcf of gas since September 2006, with no volume in the three years through April 2026. The lease carries 8 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

1 log loaded from the RRC's log index, the latest received Oct 1, 2012. Neutron. 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.
