Subsurface Monitoring Applications

  • Ground Penetrating Radars (GPR) for Pipes and Cables

    GPRs allow you to find a location, measure a depth of underground pipes, and cables, and other infrastructure items. The unique quality of GPR - they can find both metallic and non-metallic items with an equal efficiency.

  • GPR

    GPR and EM play an integral part by providing a non-intrusive means of examining the subsurface for environmental hazards such as soil contamination, underground storage tanks and drums. GPR can delineate landfills and pathways for contaminant flow, as well as conduct hydrogeologic investigations such as water table mapping. We offer innovative technology to support site assessment needs.

  • Solutions for the in-situ soil remediation

    For over twenty years, BioSolve Pinkwater has been used for Surfactant Enhanced Remediation (SER) to mobilize and solubilize residual NAPL[i], facilitating its recovery and disposal. Depending on soil and plume characteristics, Pinkwater solution can reach contaminated zones through deep injection wells or be gravity fed from surface level injection galleries. After desorbing residual NAPL from soil surfaces on contact, Pinkwater then solubilizes the hydrocarbons in an aqueous emulsion, enabling extraction at down gradient recovery wells or trenches.

  • Electrical Based Tomography Systems for Batch mixing

    Batch mixing generally refers to mixing processes in vessels and ITS tomography instrumentation provides a tool to understand, optimise and control mixing. Tomography sensors take data from between 200 to 2,400 measurement points in a single snapshot, thus providing a sound basis to monitor changes in concentration of different materials and so quantify mixing. Sensors can be retrofitted through using probe based instruments, scanning the z-axis (which usually presents the key challenge to effective mixing). Alternatively, an array of up to 8 circular planes, each with 16 electrodes can be used to provide a more complete picture of the mixing process.

  • Electrical Based Tomography Systems for Interface Detection

    Level detection is a very widespread measurement requirement. Whilst there are many techniques for detecting liquid surfaces, it is much more challenging to identify the interface between liquids and other systems.

  • Electrical Based Tomography Systems for Multiphase Flow

    Multiphase flows are complex and unpredictable however they have a significant bearing on the safety, costs and revenues of many processes – particularly in oil and gas, but also in aerospace, chemicals and other sectors.

    NAPL Fingerprinting Analysis

    Sitelab's mobile laboratory was used by a client at a former oil refinery in Kansas and at a large tank farm in Massachusetts. The UVF data was used to delineate and map subsurface plumes of NAPL. Oil samples were collected from monitoring wells and analyzed for their GRO/DRO or VPH/EPH content.

  • Electrical Based Tomography Systems for Crystallisation/Precipitation

    Crystallisation is a key reaction in pharmaceutical and other process sectors. The combination of two ionic species in solution to form a solid frequently produces a strong change in electrical properties which can be tracked using ITS electrical resistance tomography sensors. Sensor arrays are produced on two different formats:

  • Water filtration solutions for irrigation sector

    The organization model of irrigation at the same level of the basin is considered one of the best ways to use efficiently the available water and the management of this resource. One of the most successful examples of this kind of Management is the Watering Communities. These communities are consortium of farmers in charge of the organization of the use of public, surface and subsurface water.

  • Data analysis and visualization tools for geophysical analysis

    EVS, MVS, and EnterVol excel in their ability to handle analysis and visualization of geophysical data. For example, 3D resistivity can be analyzed from 2D ground arrays and airborne surveys. Electrical resistivity surveys offer the ability to inexpensively collect vast quantities of three-dimensional subsurface data. Environmental sciences, mining, archaeology and many other disciplines can benefit from these measurement techniques. However, their large irregular datasets offer significant challenges related to analysis and visualization. C Tech’s EVS , MVS, and EnterVol excel in their ability to address these complex issues.

  • Electrical Based Tomography Systems for Slurry Flow

    Slurry transportation is required in a diverse range of sectors, from food to minerals processing; and oil sands processing to nuclear waste management. As a process it requires significant levels of energy and the abrasive nature of materials used can lead to ongoing issues of pipeline erosion.

  • Fibre Optic Distributed Temperature Sensing for 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 subsurface. Traditionally, point sensors have been used to collect temperature data; however, significant limitations exist.
