Hayles Geoscience Surveys Ltd. was incorporated in Manitoba in December 1999.
This business specializes in geophysical surveys to mining, civil and geotechnical engineering, groundwater, environmental, and agricultural needs. The transportation and energy portions of our business are damaging the environment. We feel that is necessary to reduce our carbon footprint. Carbon offsets appear to be the only sensible option for us at the present time.
About 260 projects have been completed since May 1998 including:
- Economic mineral and aggregate exploration
- Industrial site remediation - buried metals
- Underground storage tank location
- Landfill & lagoon site characterizations
- Earthen embankment dam-site characterizations
- Clay search
- Agricultural site characterizations
- Depth to bedrock
- Lake and river bathymetry
- Near-surface seismic surveys
- NBCC2005 Vs30 measurements
- Saline impact
- Highway route selection
The main service is in terrain electrical conductivity (TEC) scanning using an EM-31 linked to a real-time differentially corrected global positioning system with ±0.5-m accuracy. This system provides over 3000 measurements per hour and permits the scanning of large areas in an efficient fashion just prior to drilling or excavation. There are many applications where this service is important. Deeper looking EM-34 and time-domain electromagnetic surveys are supplied. Underground storage tank scans and metal detection for restoration and remediation of former industrial sites are also offered.
The second area of expertise is in near-surface seismic surveys. State-of-the-art P-wave and SH-wave surveys are offered to provide overburden layering and depth to bedrock. Ground probing radar surveys are also provided in favourable environments.
A third area of service is in mineral exploration services. Geophysical services for airborne, surface, underground, and borehole exploration projects are offered.
Dictionary definitions:
Geophysics: The study of the earth by quantitative physical methods, especially by seismic reflection and refraction, gravity, magnetic, electrical, electromagnetic, and radioactivity methods.
Exploration Geophysics: The use of seismic, gravity magnetic, electrical, electromagnetic and/or radioactivity methods in the search of oil, gas, minerals, water, etc. with economic objectives
Geophysical Exploration: Making and interpreting measurements of physical properties of the earth to determine subsurface conditions, usually with an economic objective eg., discovery of fuel or mineral deposits. Properties measured include seismic traveltime and waveshape changes, electrical potential differences, magnetic and gravitational field strength, temperature, radioactive decay particles and rays.
