STNL

Sentinel Energy Services Inc

An integrated, employee-owned energy group that takes over late-life ("brownfield") oil and gas fields and manages them responsibly until they can be safely retired. Through affiliates like Longleaf and Forester, it handles well plugging, environmental testing, decommissioning, and surface land restoration across Oklahoma, Texas, and the Gulf Coast. The name "Sentinel" was chosen to reflect its role as a watchman responsibly "watching over" aging energy fields, and it gained many assets through a merger with legacy fields of Encino Energy.
