Prospecting. © M.-A. Merz

Applied geophysics is concerned with the exploration to find raw materials. The employed methods even permit the extent of reservoirs to be determined. This is an essential parameter, seeing as reservoirs are often too small or in too low a concentration (enrichment) in order to be mined/extracted profitably. The states in which these raw materials occur (fossil fuels such as crude oil or gas, or mineral deposits) are of no relevance for prospection. Fossil fuels are generally found at greater depths and thus require an accurate three-dimensional data acquisition for their detection i.e. measurement profiles that cross each other.
