Coke County · I. A. B. NE. (Penn. 5150) field · Producing · Vertical
N. E. I. A. B. Unit #1311 (API 42-081-31947) is a well in Coke County operated by Gtg Operating LLC, completed May 3, 2011 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued August 21, 2009, permitted to 5,170 ft.
It was permitted by Layline Petroleum I, LLC and has since transferred to Gtg Operating LLC on the wellbore schedule.
Completion filings report one formation top, including Minielle Sand.
Its lease has reported 1.3M barrels of oil and 2.79M mcf of gas since January 1993, last reporting volume in February 2026. The lease carries 74 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received May 14, 2014. Density, 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.
