Brinkley A #56
Stonewall County · Flowers (Canyon Sand) field · Shut In · Vertical
Brinkley A #56 (API 42-433-33291) is a well in Stonewall County operated by Grayrock Energy II LLC, completed January 3, 2004 and listed as shut in on the RRC schedule, shut in December 1, 2007.
The RRC has issued one drilling permit, issued October 24, 2003, permitted to 4,350 ft.
It was permitted by Walsh & Watts, Inc. and has since transferred to Grayrock Energy II LLC on the wellbore schedule.
Completion filings report 5 formation tops, including Coleman Junction, Gunsite, Tannehill, Swastika.
Its lease has reported 303K barrels of oil and 190K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 52 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Mar 23, 2007. Gamma ray, Resistivity, Spontaneous potential. 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.
