Geophysical Methods Used in Mineral Prospecting (Non Oil and Gas) Besides seismic methods, varieties of geophysical methods are used in mineral prospecting and they are chosen based on the targeted minerals and their deposit settings.
Gravity prospecting is used as a reconnaissance tool in oil exploration; although expensive, it is still considerably cheaper than seismic prospecting. Gravity data are also used to provide constraints in seismic interpretation. In mineral exploration, grav ity prospecting usually has been employed as a sec
Seismic Surveys are used to produce images of the various rock types and their location beneath the Earth's surface. Seismic information accurately plans the location and size of oil and gas wells, reducing the need for further exploration and minimising environmental impact.
Various geophysical prospecting techniques (, seismic reflection methods, electromagnetic methods, electrical methods, infrared detection methods) are used as dominant methods to detect the geological structures and identify the adverse geological bodies.
Description. Oil and Gas Exploration: Methods and Application presents a summary of new results related to oil and gas prospecting that are useful for theoreticians and practical study of oil and gas complexes and intrusions occurring in sedimentary basins is crucial for identifying the location of oil and gas fields and for making accurate predictions on oil findings.
The use of seismic methods is not very practical and is not costeffective because mentioned methods can be easily achieved to the goal. 10 months ago dr. adel Kotb
Here is a brief explanation about the advantages and the disadvantages of the different methods of geophysical surveys used in mineral prospecting.
assignment of seismic prospecting to one of the methods in experimental physics for obtaining acoustic sections as final products contradicts the geological content of the method. Another, rather important feature of the contemporary method of seismic prospecting is .
