Gregg County · Danville (TP-CV Cons.) field · Producing · Vertical
Gunn Margaret GU 1 #12 (API 42-183-31859) is a well in Gregg County operated by Sydri Operating LLC, completed November 3, 2006 and listed as producing on the RRC schedule, shut in October 1, 2024.
The RRC has issued one drilling permit, issued February 27, 2006, permitted to 10,875 ft.
It was permitted by Burlington Resources O & G CO LP and has since transferred to Sydri Operating LLC on the wellbore schedule.
Completion filings report 6 formation tops, including BMA, Pettit, Travis Peak, Cotton Valley.
Its 2 leases have reported 7.8K barrels of oil and 591K mcf of gas since November 2006, last reporting volume in September 2024. The leases carry 2 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Jul 23, 2008. Density, Neutron, Resistivity. 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.
