Geophysical Survey Demand Driving New Technology Development Geophysical survey companies are experiencing significant growth due to increases in the number of mineral and oil exploration projects worldwide. Declines in reserves are directly tied to an increase in funding for exploration activities. Geophysical surveys are an essential part of these exploration processes and are imperative to … Read more
Geophysical companies conduct efficient geophysical explorations for governments, individuals, mapping professionals, mining companies and others who who depend upon geoscientific data. Some of the applications are indicated below: Efficient geophysical exploration surveys employ the use of precise airborne geophysical data acquisition systems to ensure that the data obtained during a survey is highly precise and … Read more
What is Geophysics? Geophysics uses high tech, sensitive instrumentation to detect and analyze various physical properties of the Earth, which are linked to its geology. Geophysical surveys are the collection and mapping of geophysical data. This data can prove invaluable to mining companies, oil companies and other companies as it helps to provide a means … Read more
Geophysical exploration is a means of sourcing out high concentrations of various minerals and commodities under the Earth’s surface by employing surveying methods, such as electromagnetic surveys and magnetic surveys. Geophysical exploration can be conducted on the ground or by air and can detect a variety of different magnetic mineable ores such as kimberlites and … Read more

Starting with initial survey design and an extensive review of the client’s survey targets and goals, Terraquest incorporates an experienced Geophysicist from the start of the planning process to provide input into extensive survey planning including, There … Read more
The Demand for Airborne Geophysical Surveys Greater global demand for minerals and hyrdocarbons is leading to an increased demand for geophysical surveying. Airborne geophysical surveying, in particular magnetics, electromagnetics, and radiometrics, have become the leading techniques to initiate the mineral exploration process and gravity and magnetics are used in hydrocarbon applications. Airborne survey data can … Read more
Geophysical surveying is a technique of the mining industry which uses a specialized instruments to measure the physical properties of rocks and soil in the surface and subsurface. The goal of geophysical surveying is to detect and/or predict the presence and position of elements and minerals, ground water, oil and gas and other components of … Read more
Introduction to Airborne Magnetic Surveys Airborne magnetic surveying is a geophysical method used to image anomalies in the earth’s magnetic field caused by variations in the magnetization of the crust. These variations may be indicative of structural or lithological contrasts in the subsurface. Magnetic data can be collected on the earth’s surface, from the air, … Read more
