Chapman-Abbott Unit #8
Williamson County · Chapman Abbott field · Shut IN · Vertical
Chapman-Abbott Unit #8 (API 42-491-30327) is a well in Williamson County operated by Genesis Well Service, completed December 1, 1984 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued August 30, 1983, permitted to 2,500 ft.
It was permitted by Sun Expl. & Prod. CO.-Houston and has since transferred to Genesis Well Service on the wellbore schedule.
Completion filings report one formation top, including Serpentine.
Its lease has reported 231K barrels of oil and 780 mcf of gas since January 1993, last reporting in July 2026. The lease carries 52 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Sun Expl. & Prod. Co.-Houston; the EWA schedule now lists a different operator.
