Terry County · Wellman W. (San Andres) field · Horizontal · Sidetrack
Wellman West Unit #35 H (API 42-445-31894) is a horizontal well in Terry County operated by White Rock Oil & Gas LLC, completed March 31, 2000.
The RRC has issued 3 drilling permits (amended once) between 1999 and 2005, permitted to 5,700 ft.
It was permitted by Devon Energy Production CO, L.P. and has since transferred to White Rock Oil & Gas LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Rustler, Yates, San Andres.
Its lease has reported 2.04M barrels of oil and 460K mcf of gas since January 1993, last reporting in July 2026. The lease carries 45 wells, so these are lease totals, not this well alone.
