Complementary Geophysical Methods - The DMT Advantage
DMT Geosciences specializes in the acquisition, processing and interpretation of near-surface geophysical data. Converse to the approach of organizations that rely on a small selection of methods, DMT draws from a wide range of available tools with the necessary experience to determine those most suitable for the survey objectives. DMT's personnel are among the world's most experienced practitioners of shallow seismic reflection and refraction, ground penetrating radar (GPR) and capacitive coupled resistivity. In addition, DMT has considerable experience with airborne geophysical data interpretation.
Ground penetrating radar, also called Georadar, can be used to locate objects, cracks or other damages in rock, soil and other materials. GPR data can also be used in environmental remediation. GPR offer high-frequency subsurface measurements that are non-invasive and non-destructive, thus saving time, costs and resources. DMT recommends to use ground penetrating radar in combination with other geophysical methods and integrate the data in the radargram into a larger context to get a more accurate interpretation. We measure soil resistivity, conduct magnetic surveys and compile your customized geophysical report for your project.
Among the additional services we provide are soil imaging or soil surveys as well as borehole logging and other methods. Borehole logging is being used to assess the composition of rock formations, also called lithology, for oil & gas exploration or mineral exploration. The lithological data can then be used for project planning and to identify potential extraction areas.
Soil surveys or soil mapping is used to identify different types of soil. For Canada, especially permafrost mapping is a relevant application.
