Mabee 139 #301H (API 42-317-38772) is a plugged horizontal well in Martin County, plugged September 1, 2021, last operated by Cog Operating LLC.

The RRC has issued one drilling permit, issued July 11, 2013, permitted to 13,000 ft.

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

Completion filings report 10 formation tops, including Santa Rosa, Yates, Seven Rivers, Queen.

Its lease has reported 179K barrels of oil and 1.21M mcf of gas since January 2015, last reporting volume in April 2026. The lease carries 2 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 Jan 25, 2018. 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.
