Butterfly #10 (API 42-475-35442) is a well in Ward County operated by Seaboard Operating CO., completed December 15, 2008 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued August 9, 2008, permitted to 5,300 ft.
It was permitted by Texon Oil Company, Inc. and has since transferred to Seaboard Operating CO. on the wellbore schedule.

Its lease has reported 575K barrels of oil and 1.43M mcf of gas since September 2005, last reporting in July 2026. The lease carries 16 wells, so these are lease totals, not this well alone.
