Ector County · Spraberry (Trend Area) field · Shut In · Vertical
Gardendale 12 #16 (API 42-135-40957) is a well in Ector County operated by Diamondback E&P LLC, completed January 22, 2021 and listed as shut in on the RRC schedule, shut in October 1, 2026.
The RRC has issued one drilling permit (amended once), issued May 20, 2011, permitted to 11,370 ft.
It was permitted by Berry Oil Comp. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 13 formation tops, including San Andres, Clear Fork, Spraberry, Dean.
Its lease has reported 868K barrels of oil and 3.46M mcf of gas since September 2010, last reporting volume in April 2026. The lease carries 11 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 19, 2015. 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.
