Slurry Fracture Injection – SFI

SFI™ is an environmentally sustainable technology used to place petroleum exploration and production (E & P) waste, Biosolids & contaminated soils in the deep subsurface (geo-sequestration). SFI is a permanent Zero Discharge disposal solution.

Zero Discharge-Exploration and Production (ZD-E&P) refers to oilfield upstream operations that generate various waste streams, and managing these waste streams so there is no (or minimal) negative interaction with the biosphere (soil, surface water, ground water, and air quality).

Terralog’s Services are built on our extensive experience in deep well disposal of E&P waste streams; combined with expertise in geomechanics, geology, rock mechanics, reservoir engineering, and environmental management with practical field experience in long-term deep well injection operations.

Phases of an SFI project

A series of project development phases need to be conducted to properly assess, design and implement the Slurry Fracture Injection (SFI) process for the disposal of E&P wastes such as oily sludge, etc.,

Terralog’s SFI services typically have 3 development phases. Each phase incorporates project planning that includes correspondence and meetings with appropriate client teams to ensure the specific project objectives and tasks are defined.

Phase 1 – Technical Feasibility Study (TFS)

This phase is designed to look at some fundamental parameters effecting the viability of the SFI project or any deep well waste disposal project. The TFS phase addresses issues such as:

  • •    Geological assessment: determine if there is suitable stratigraphy and disposal formations for SFI operations; determine the target, containment, and confining zones required for SFI operations; characterize and map out this zones.
  • •    Waste material audit.
  • •    Basic fracture mechanics in possible target SFI formations.
  • •    Slurry design considerations.
  • •    Equipment requirements.
  • •    Disposal well requirements and design.
  • •    Preliminary SFI project design & recommendations - ensure 'best practice' standards of large-scale slurry injection operations.
Phase 2a: SFI FEED Study and regulatory support

This FEED phase addresses issues such as:

  • •    Conduct field site assessments.
  • •    Formation testing program.
  • •    Design startup.
  • •    Process FEED: Finalizing process design specifications such as equipment requirements and material transportation.
  • •    Facility FEED: Finalizing SFI facility design specifications including: required design, size, and type of SFI pads at the SFI facility.
  • •    Develop a comprehensive project implementation schedule/task-plan.
  • •    Develop a plan/strategy for regulatory permitting and approval of the project.
Phase 3: full scale SFI operations

  • •    Complete injection services in the field (equipment, personnel, and injection operations)
  • •    Project management & engineering services: environmental & operational assurance
