Electrical resistivity survey for groundwater investigations

Exploration geophysics is an applied branch of geophysics, which uses physical methods, such as seismic, gravitational, magnetic, electrical and electromagnetic at the surface of the Earth to measure the physical properties of the subsurface, along with the anomalies in those properties. It is most o

Since the introduction of high-resolution electric instrument adhere to the "forecast ingress, suspicious, first exploration, first after excavation, first cure and then mining" principle of water exploration, has carried out high-resolution advanced detection more than 20 times, effective detection

Vertical electrical sounding (VES) is commonly used to solve many problems regarding groundwater assessment, investigation, exploration, quality/pollution, the boundary, thickness and depth of the aquifer with its different layers

The inclinometer system consists of an inclinometer casing and an inclinometer measurement system. The casing provides contact for sub-surface measurements, while its grooves control the orientation of the inclinometer sensor and provide a uniform surface for measurements.The casing is usually insta

Seismic Reflection (both on-shore and marine) is the most common geophysical methodology used for oil and gas exploration and exhibits the highest degree of technical sophistication in terms of both data acquisition and signal processing capabilities. Seismic reflection surveys provide either 2 or 3

The prospecting method refers to the general name of the working methods and technical measures adopted in order to find the ore deposit. There are mainly geological methods, geophysical methods, geochemical methods, and remote sensing methods.Prospecting ore, also known as prospecting, or census or

Borehole LoggingGeophysical borehole logging can provide accurate data of the physical properties of geologic units and groundwater within the borehole environment.Borehole logging is a time and money-saving approach to gaining detailed information which is otherwise only obtainable from performing

Transient electromagnetic detection has the following advantages⑴ Due to high construction efficiency, pure secondary field observation and sensitivity to low-resistance bodies, it has become the preferred method in the current coalfield hydrogeological exploration;⑵ Transient electromagnetic method

Induced polarization (IP) is a geophysical imaging technique used to identify the electrical chargeability of subsurface materials, such as ore. The polarization effect was originally discovered by Conrad Schlumberger when measuring the resistivity of rock.
