Steam injection was first developed to enhance oil recovery by loosening heavy oil and causing it flow towards wells for extraction. Steam Enhanced Extraction (SEE) technology is used in environmental projects to make subsurface NAPL less viscous so it can move more freely to extraction wells.
TerraTherm, a Cascade Company’s SEE innovations include pressure cycling which allows us to extract the lighter-end contaminants and effectively deplete the organics in mobile contaminants.
SEE achieves on-site separation and treatment from steam injection into wells and extraction of hot fluids. Steam propagation is a stable and predictable process, governed by the heat transfer to the formation.
Cascade uses SEE to treat our client’s groundwater problems and to prevent expensive excavation of the source areas.
SEE can deliver more energy to the subsurface at a lower cost than either thermal conduction heating (TCH) or electrical resistance heating (ERH). This makes SEE an effective remediation approach for:
