The SFI technology is used to dispose of large volumes of granular and viscous fluid wastes into deep geological structures. SFI is used as a deep well disposal solution for a variety of waste streams:
- NORM & low-level radioactive waste streams (LLRW)
- Contaminated soils, sludge & tailings
- Petroleum industry E&P waste streams: produced solids, oily sludge, tank/pit bottoms, crude oil contaminated soils, drilling waste, & NORM.
- Large volumes of produced water or waste water are also injected/ disposed as part of SFI deep well disposal operations.
Extensive process monitoring must be utilized during SFI operations in order to ensure effective Process Control.
- Process Control can be defined as follows:
- Ensure in situ formation containment
- Optimize formation response to injection operations
- Maximize formation storage capacity
- Mitigate wellbore integrity risks
TTI has developed the industry Best Practices for deep well disposal based on comprehensive expertise in the design, management, and operation of large-volume SFI deep well waste disposal projects.
