Survey Design
Greg Street , principal of GeoAg has more than 30 years experience in the geophysics industry and has carried out or supervised surveys for minerals, agriculture, groundwater, environment, engineering and oil. We can design your survey for maximum benefit, assist in contractor selection and provide quality assurance services.
QA
GeoAg provides quality assurance services for a wide range of geophysical surveys ranging from shallow seismic refraction and reflection, airborne geophysics to ground based surveys for groundwater, mineral exploration or oil.
Acquisition
GeoAg provides data acquisition services for small surveys or can assist in your selection of a contractor suited to clients needs. GeoAg has the ability to acquire data in EM, ground radiometrics, shallow EM, GPR, downhole logging, magnetics and seismic refraction surveys.
Downhole Logging
GeoAg can provide services in downhole logging using conductivity, gamma, resistivity or other specialized tools.
Shallow Electromagnetics
Electromagnetic surveys using frequency domain EM equipment are regularly carried out both by GeoAg personnel or supervised by us. Surveys have been carried out for seepage detection, site assessment, landfill delineation, road damage, cavity detection, drum detection, archeology, slope stability, land capability, salinity and drainage design.
Airborne EM
GeoAg are specialists in the interpretation of airborne electromagnetic (AEM) surveys for environmental purposes particularly in salinity, groundwater and other regolith applications. Data can be processed using state of the art software to highlight information of interest.
Airborne Radiometrics
Airborne radiometric surveys are now a tool to improve soil maps. GeoAg can process data to get maximum information as well as interpret radiometric data through to detailed soil maps. Mining sites can be mapped for radioactive waste or clean-up. Airborne radiometric surveys also can be used for mapping fallout from nuclear explosions or accidents. Data can be processed to highlight various fallout products from natural background.
Airborne Magnetics
GeoAg are experts in the application of airborne magnetic surveys for groundwater, salinity or other regolith studies. Magnetics can be processed and interpreted to highlight structures of interest for groundwater exploitation or others that may be causing dryland salinity.
