Silixa’s distributed fibre optic sensing technologies allow for unparalleled capability for characterizing geothermal reservoirs. Our class leading iDAS and ULTIMA DTS systems are readily combined allowing for the maximum amount of insight into the reservoir to be achieved from a single installation. Monitoring solutions can be installed both downhole and at the near surface for either short term geothermal field characterization or for long term asset optimization. Example specific applications of our technology include:

Temperature Characterization

Our ULTIMA™ DTS offers unparalleled resolution performance and can be used to optimize production and maximize geothermal reservoir thermal performance.

Fracture Interconnectivity

Insight into the interconnectivity of permeability between wells can be provided by combining characterization methods based on our distributed sensing technology.

Permeability Enhancement

iDAS and ULTIMA DTS systems can be combined to both guide and monitor permeability enhancement for Enhanced Geothermal Systems (EGS).

Well Field Optimization

Improved utilization of existing infrastructure can be obtained minimizing the necessity for investment in drilling programs.

Active Characterization

Our ULTIMA DTS system can be deployed using an active measurement approach which utilizes response data to determine both reservoir thermal properties and flow distribution.

Key benefits

  • Advanced characterization of geothermal reservoirs
  • Optimization of existing assets
  • Unparalleled measurement capability
  • Improved decision making capacity
  • Suitable for harsh and high temperature environments common in geothermal fields
  • Both high resolution characterization and continuous monitoring capabilities

Reservoir flow heterogeneity can be characterized using both active and passive DTS to optimize geothermal fluid production and injection processes.

How does it work?

Silixa’s fibre optic distributed sensing technologies allow for the collection of data at all locations of up to tens of kilometres of optical fibre simultaneously, transforming both standard and customized cable solutions into the equivalent of thousands of point sensors. This fundamental advance in sensing technology provides a means for characterization of geothermal reservoirs and reservoir processes at spatial and temporal scales that were previously not possible.
