Murphy Unit #1 (API 42-041-31114) is a well in Brazos County operated by Chaparral Energy L.L.C., completed April 27, 1984.
The RRC has issued one drilling permit, issued March 2, 1984, permitted to 10,500 ft.
It was permitted by Inexco Oil Company and has since transferred to Chaparral Energy L.L.C. on the wellbore schedule.
Completion filings report 3 formation tops, including Austin Chalk, Eagle Ford, Woodbine.
Its 2 leases have reported 27.3K barrels of oil and 868K mcf of gas since January 1993, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
