Prideaux Nellie #9A
Young County · Young County Regular field · Shut IN · Vertical
Prideaux Nellie #9A (API 42-503-40751) is a well in Young County operated by Kelly Mahler Operating LLC, completed September 2, 1996 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued May 14, 1996, permitted to 1,000 ft.
It was permitted by Peterson & Roberts and has since transferred to Kelly Mahler Operating LLC on the wellbore schedule.
Completion filings report 2 formation tops, including Trinity Water Sand, Gunsight.
Its lease has reported 44.4K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 15 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
Operator of record
