Advanced deep well disposal process

Page last modified

August 4 2023

The Slurry Fracture Injection (SFI) process is an environmentally sustainable technology used to place petroleum E&P waste, NORM, biosolids, and contaminated soils in the deep subsurface. SFI advanced deep well disposal is characterized by:

Lower injection rates & pressures
Continuous, cyclic injection operations
Development of complex geomechanics
Controlled development of a formation ‘waste pod’ in the near-wellbore area and out into the far-field formation
Robust Process Monitoring & Process Control systems
Cost-effective, Zero-Discharge, and permanent disposal process
Small environmental footprint

Pro/con

Protection of underground sources of drinking water

Elimination of run-off & contamination risks to surface and groundwater

Elimination of surface land use impairment

No induced seismicity

Elimination of long-distance waste material transportation risks and costs

Greatly reduces long-term liability to operator/generator

Safeguards human health by reducing and removing pollution from the biosphere

Contributes to an efficient and economical waste management strategy

Permanent Zero-Discharge waste disposal

SFI process is geology-dependent for large scale disposal operations

Specification

Certifications / licences Terralog’s systems for SFI design & implementation are certified to ISO 9001:2015, ISO 14001:2015, and OHSAS 18001:2007.

Depth Typical disposal depths: 350 – 2,500 m.

Environment SFI has a proven environmental record of Zero-Discharge waste disposal, with no impact on future land use.

Grain size SFI can effectively dispose of materials with grain sizes up to 5 mm. The slurry is made with the highest possible solid material concentration – from 10 to 25 percent by volume.

Safety Safeguards human health by reducing and removing pollution from the biosphere.

Volume Large waste volumes (up to 15,000 m3 per month).
