Shirley A #3409 (API 42-329-38266) is a plugged well in Midland County, plugged February 22, 2024, last operated by Diamondback E&P LLC.
The RRC has issued one drilling permit, issued September 13, 2012, permitted to 11,500 ft.
It was permitted by Energen Resources Corporation and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Wolfcamp, Strawn.
Its lease has reported 59.9K barrels of oil and 81.6K mcf of gas since April 2011, with no volume in the three years through April 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

Well logs
2 logs loaded from the RRC's log index, the latest received Jan 17, 2014. 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.
