McMullen County · WRK (Jackson 2250) field · Producing · Vertical
Wrk #1 (API 42-311-33629) is a well in Mcmullen County operated by Hilcorp Energy Company, completed June 1, 2001 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 21, 2000, permitted to 2,450 ft.
It was permitted by Maverick Energy & Dev. Corp. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report one formation top, including Jackson.
Its lease has reported 35.6K barrels of oil since June 2001, last reporting in July 2026. The lease carries 3 wells, so these are lease totals, not this well alone.
