Winkles #3
Gaines County · Carm-Ann (San Andres) field · Producing · Vertical
Winkles #3 (API 42-165-36644) is a well in Gaines County operated by R2q Operating LLC, completed November 8, 2006 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued September 8, 2006, permitted to 5,115 ft.
It was permitted by Cog Operating LLC and has since transferred to R2q Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Seven Rivers, Grayburg, San Andres.
Its lease has reported 101K barrels of oil and 67.7K mcf of gas since June 2006, last reporting volume in April 2026. The lease carries 3 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Apr 16, 2007. Cased hole, Gamma ray, Neutron. 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.
