The measurement of electrical resistivity of the subsurface is one of the oldest geophysical methods (VES). It was developed during the late 1980s and the early 1990s as an electrical 2D and 3D imaging method for mapping the resistivity distribution in the subsurface CVES/ERT. Electrical resistivity is effective for shallow ...

Geophysical surveys are used to create maps of subsurface archaeological features. Features are the non-portable part of the archaeological record, whether standing structures or traces of human activities left in the soil. Geophysical instruments can detect buried features when their electrical or magnetic properties contrast measurably with their surroundings. ...

Most coal companies rely heavily on borehole data to evaluate their mine properties. However for the Underground Coal Gasification (UCG) and Coal Bed Methane (CBM) it is necessary to map the subsurface coal and to detect other spatial properties of the coal seam with a high degree of accuracy. Here the geophysical technology plays a vital role. The following are ...

by:Geotec Engineering & Environmental Geophysics Ltd based inrishon letzion, ISRAEL
A seismic survey is based on an energy source that excites seismic (elastic) waves in the subsurface. The seismic waves propagate in the subsurface and are reflected or refracted in the interfaces between mediums, having a different seismic velocity. The reflected and refracted waves are recorded on the surface by an array of receivers (geophones). The recorded travel times between the source and ...

Electromagnetic methods (FDEM, TDEM) were developed for the purpose of measuring resistivity in the subsurface. The methods are used extensively around the world to provide solutions to engineering and environmental problems. These methods, which enable penetration to relatively great depths (up to hundreds of meters), allow to carry out deep measurements at a very high level of accuracy. In ...

The purpose of electrical surveys is to determine the subsurface resistivity distribution by making measurements on the ground surface. From these measurements, the true resistivity of the subsurface can be estimated. The ground resistivity is related to various geological parameters such as the mineral and fluid content, porosity and degree of water saturation in the rock. Electrical resistivity ...
