Gaines County · Salisbury (L. Leonard Sd.) field · Producing · Vertical
Fields #4 (API 42-165-36598) is a well in Gaines County operated by R2q Operating LLC, completed September 22, 2006 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued June 23, 2006, permitted to 7,800 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 Yates, Queen, Glorieta.
Its lease has reported 487K barrels of oil and 378K mcf of gas since March 2001, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
