GEOPHYSICAL SURVEYS

At DMT Geosciences, we provide geophysical consulting services to a wide variety of clients from a broad range of disciplines. Our clients have included some of the world’s largest mining and oil & gas companies, government, specialist engineering, environmental consultancies, and junior mining companies throughout Canada and around the world. We provide quality control, compilation and processing, modelling and interpretation of geophysical data as well as project design and management of geophysical surveys of all sizes.

We provide service through every stage of a project including:

Project design and management
Compilation and processing of geological and geophysical data
Modelling and inversion capabilities for magnetic, gravity and EM data
Interpretation and visualization of large, multi-survey geophysical data sets

GEOPHYSICAL DATA PROCESSING & INTERPRETATION

We have the software and expertise to process, combine and interpret a wide range of geophysical data sets, incorporating existing geologic knowledge where available. We have experience in ground, airborne and marine surveys.

Our expertise encompasses:

Reflection Seismic
Refraction seismic
MASW
Passive seismic
Electrical Resistivity
Frequency domain electromagnetics
Time domain electro-magnetics
Mise-a-la-masse

Borehole logging
Cross-hole seismic
Full wave-form sonic
Capacitively coupled resistivity
Ground Penetrating Radar
Gravity
Magnetic
4-pin grounding surveys

Resistivity data used to develop a 3D model of contaminated zone for environmental client. Geophysical Data were correlated with water and soil analysis data. (presented at GeoEdmonton, 2018)

EXPERT STUDIES

Not all projects can be successfully completed using conventional geophysical techniques. At DMT, our team of geoscientists consult on unique challenges to develop innovative solutions for our clients in the environmental, engineering and resource sectors. From desk top modeling studies to field surveys, our scientists backed by DMT’s diverse international team, bring a breadth and depth of experience to each project.

Our specific expertise includes:

Mapping fluid related geohazards in the oil & gas and mining sectors
Mapping saline aquifers in environmentally sensitive zones.
Full 3D modeling of electromagnetic and resistivity surveys to design optimal survey parameters for unique and challenging targets
Harnessing the processing power of SimPEG and Python to develop custom solutions to unique projects that do not suit the traditional off-the-shelf methods.
Customized monitoring solutions for engineered hydraulic barrier installations aimed at providing actionable information in addition to a map of geophysical properties.
Coastal fluid seepage pathway and marine hazard mapping.

Compilation of airborne geophysical data sets spanning 10 years with multiple instruments. Mapped are paleochannels vital for water resources and environmental planning. (Presented at CSEG2016)

HISTORIC DATA SETS

DMT is adept at revisiting old geophysical data with new processing techniques, new methods of visualisation and a modern perspective as an effective way of improving the understanding of a site at low cost.

New data can be used to refine inversions of old geophysical data sets and an improved 3D image of the subsurface produced.

Previous projects include:

Refining 2D seismic processing and interpretation upon new drill results
Combining multiple airborne data sets collected over a span of 15 year and multiple systems
Reinverting focused areas of regional airborne geophysical to address specific client objectives, providing cross-sections and 3D images of target areas.
