Gunn Margaret G.U. 1 #5 (API 42-183-31640) is a well in Gregg County operated by Sydri Operating LLC, completed May 2, 2004 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued January 21, 2004, permitted to 10,853 ft.
It was permitted by Geo-Vest Of Texas, Inc. and has since transferred to Sydri Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Top Of Bexar Shale, James Lime, Pettit.
Its 2 leases have reported 3.73K barrels of oil and 942K mcf of gas since March 2004, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.

Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.

Well logs
1 log loaded from the RRC's log index, the latest received Jun 7, 2007. Density, Gamma ray, 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.
