Reeves Unit #143 (API 42-501-33636) is a well in Yoakum County operated by White Rock Oil & Gas LLC, completed May 4, 1991 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 21, 1990, permitted to 5,752 ft.
It was permitted by Santa FE Energy Oper. Part., LP 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 12.7M barrels of oil and 4.87M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 259 wells, so these are lease totals, not this well alone.
