Mabee J.E. B Nct-2 #1511H (API 42-317-39958) is a horizontal well in Martin County operated by Cog Operating LLC, completed July 12, 2015 and listed as shut in on the RRC schedule.

The RRC has issued one drilling permit, issued October 13, 2014, permitted to 10,843 ft.

It was permitted by Chevron U. S. A. Inc. and has since transferred to Cog Operating LLC on the wellbore schedule.

Completion filings report 18 formation tops, including Santa Rosa, Yates, Queen, Grayburg.

Its lease has reported 1.27M barrels of oil and 2.68M mcf of gas since July 2015, last reporting volume in April 2026. The lease carries 7 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 Nov 10, 2015. 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.
