Near-Surface Geophysics

In addition to geophysical surveys for the oil exploration industry, GII is engaged in environmental and engineering geophysics, as well as groundwater resources exploration.
Rapid and accurate mapping of the structure and physical properties of the subsurface is essential to a variety of applications and therefore, much attention is devoted to shallow subsurface surveys:

Civil engineering	Environment	Groundwater	Archeology
Earthquake hazard & risk assessment	Vibration monitoring	Detailed aquifer mapping	Location of subterranean ruins
Site response for construction of bridges, runways, large buildings, electric & nuclear power plants	Detection of oil leaks & seepage of toxic materials	Mapping of contaminant flow	Void detection
Mapping of geological faults	Detection of underground pipes, cables & storage tanks	Monitoring sea water intrusion and salinity estimation	-
Mapping soil / bedrock contact	Waste sites exploration	Wellsite Geology	-
Calculation of elastic dynamic parameters	Sinkhole investigation	-	-

For studying the shallow subsurface, GII utilizes state of the art methods and technologies:

* Seismic methods: refraction (P&S waves), reflection, surface wave analysis and borehole measurements

* Engineering Seismology

* Vibration Monitoring

* Ground Penetrating Radar (GPR)

* Geoelectric & Electromagnetic

* Microgravity
