Not one formation; the well must be completed in one of them, and no target formation is stated.

Mabee 239a #1308 (API 42-317-38648) is a well in Martin County operated by Cog Operating LLC, completed January 30, 2014 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued May 2, 2013, permitted to 12,258 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, Queen, Grayburg.

Its lease has reported 163K barrels of oil and 339K mcf of gas since December 2012, last reporting volume in April 2026. The lease carries 3 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 20, 2017. 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.
