Environmental and Geo Hazard Assessment

Environmental Impact Assessments (EIA) are fundamental to minimising the risk to and maximising the success of E&P projects. Metatek can provide all the technical studies necessary to assess the potential impact of a project to the socioeconomic, atmosphere, aquatic, and terrestrial environments.

Metatek assess a wide range of environmental effects in both marine and terrestrial environments, as well as human and cultural changes in land use, population levels, socioeconomic levels and atmospheric emissions.

Our specialists investigate and evaluate the potential environmental constraints together with opportunities associated with our clients’ projects with the outcome of proposing appropriate and pragmatic mitigation and management measures. This assists the regulatory approval process and serves to achieve good environmental and social outcomes.

Environmental and Geo Hazard Assessment

Techniques utilised include LiDAR Remote Sensing (LRS) technology which measures distance by illuminating a target with a laser and analysing the reflected light. Applications include:

  • Flood and drainage mapping
  • Glacier and snowfield mapping
  • Agriculture and forestry mapping
  • Monitoring of open-cast mining
  • Rugosity mapping for land access planning

Hyperspectral Remote Sensing (HRS) extracts physical information across the spectrum to describe the inherent properties of the targets. Regions can be quantitatively analysed for a wealth of natural and artificial materials, such as vegetation, water, gases, soils and rocks. Potential applications include:

  • Mineral mapping
  • Water quality and oil spill detection
  • Vegetation mapping, health and distribution
  • Forest inventory

Other remote sensing techniques for monitoring and change detection include gradiometry, gamma-ray spectrometry, digital terrain and surface models, thermal infrared imagery, and image analysis.

Metatek also provides several ground verification programmes, including:

  • Calibration of remote sensing data
  • Hard rock geochemistry (ICP-MS, Mass Spectrometry)
  • Wet geochemistry
  • ISO 17025 and MCERTS standards
  • Vegetation sampling and archiving
