Three Sisters #4
Glasscock County · Cobra (Wolfcamp) field · Vertical
Three Sisters #4 (API 42-173-36061) is a well in Glasscock County operated by Hannathon Petroleum LLC, completed October 5, 2013.
The RRC has issued 2 drilling permits (amended once) between 2013 and 2015, permitted to 11,000 ft.
It was permitted by Mdc Texas Operator LLC and has since transferred to Hannathon Petroleum LLC on the wellbore schedule.
Completion filings report 3 formation tops, including San Andres, Clear Fork, Wolfcamp.
Its 2 leases have reported 883K barrels of oil and 329K mcf of gas since June 2012, last reporting in July 2026. The leases carry 5 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 403K barrels injected in the 12 months reported through January 2026.
