  • Hydro - Temperature Monitoring for Seepage Detection in Dams

    Hydro - Temperature Monitoring for Seepage Detection in Dams

    Distributed seepage detection uses the natural seasonal temperature variations that occur in all surface water, such as lakes, reservoirs and rivers. The seepage flow causes a seasonal temperature variation inside the dam. With Silixa’s range of distributed fibre optic sensing technologies and fibre optic cables this seasonal temperature variation can be measured with good spatial resolution along an embankment or tailings dam. The measured data...

  • Process Monitoring

Our ULTIMA™ DTS and iDAS™ provide the finest distributed sensing performance available offering an unsurpassed level of insight into industrial processes. Combined with customised installation, cable, and software solutions from our team of expert engineers...

  • Stream Monitoring Services

    Stream Monitoring Services

    Temperature is an important factor in streams ecosystems. Heat tracers have been used to characterize contaminant transport, infiltration rates and energy exchange with groundwater, the atmosphere and radiation. The dynamics of these complicated water bodies is also affected by seasonal and diurnal patterns making characterization particularly challenging. Utilizing temperature measurements that capture spatial and temporal variations at stream...

  • Borehole Flow Monitoring

    Borehole Flow Monitoring

    Subsurface environments are critical not only as water resources but also for energy use including geothermal, CO2 sequestration and oil & gas operations. These sensitive environments are directly affected by anthropogenic activities, hence monitoring is essential. Temperature offers insight into a variety of physical properties and can be used for flow monitoring and flux quantification in the...

  • Seismic Monitoring

    Seismic Monitoring

    The intelligent Distributed Acoustic Sensor (iDAS), when coupled to an optical fibre, provides a versatile seismic acquisition platform capable of meeting many borehole seismic objectives.

  • Production Monitoring

    Production Monitoring

    Characterising fluid movement within the well can be the key to understanding and optimising well performance; Silixa’s intelligent Distributed Acoustic (iDAS) and Distributed Temperature Sensors (ULTIMA DTS) offer a means to efficiently gather production or injection profiles along the entire wellbore with minimal or no intervention.

  • Fracture Monitoring

    Fracture Monitoring

    Typically the optical fibre cable will be placed on the outside of the production casing on a plug and perforate completion which requires a specific installation technique and oriented perforation solution to ensure the cable is preserved throughout the completion phase and beyond. The optical fibres provide an in-situ sensor array that makes it possible to acquire temperature and true acoustic information at every point along the cable path. This is...

  • Well Integrity

    Well Integrity

    Well integrity can be summarised as the application of equipment and procedures to prevent the uncontrolled release of well fluids throughout the life of the well. This is achieved by including multiple well barriers into the well design, each of which must function normally to maintain the desired redundancy to ensure on-going well integrity.

  • CO2 Well Monitoring

    CO2 Well Monitoring

    Many of the in-well iDAS and DTS applications targeted at the upstream oil and gas industry are also a natural fit for CO2 well monitoring. Silixa have played an active part in the installation of fibre optic enabled monitoring systems for carbon capture and storage projects and continue to acquire data on several of these projects for a variety of reasons.

  • Pipeline

  • Leak Detection

    Leak Detection

    Temperature based leak detection is based on Silixa’s Distributed Temperature Sensor (ULTIMA DTS) offering multiple channel configurations up to 35 km per channel on either single mode or multimode fibre.

  • Third Party Intrusion (TPI)

    Third Party Intrusion (TPI)

    Acoustic detection technology is used to measure the acoustic signature comprising of the amplitude, frequency and phase at every point along the optical fibre. Silixa’s technology is able to discriminate multiple simultaneous third party intrusion events and locate them accurately along the pipeline. Events are detected and classified using a neural network processing architecture before a decision is made.
