Summerlee Unit #8
Hardeman County · Bbbb (Congl.) field · Producing · Horizontal
Summerlee Unit #8 (API 42-197-31588) is a horizontal well in Hardeman County operated by Assent Energy Partners LLC, completed October 23, 2008 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits (amended once) between 2005 and 2006, permitted to 8,199 ft.
It was permitted by Cimarex Energy CO. and has since transferred to Assent Energy Partners LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Barnett, Chester, Chappel Lime.
Its 2 leases have reported 13.9K barrels of oil since November 2005, last reporting in July 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
