Abstract

Exploration and exploitation of natural resources is one of the main concerns of an earth scientist to benefit humanity. Any country’s economic growth and development can be judged from the availability of natural resources. Electrical and electromagnetic methods are quite useful in the exploration of oil, mineral, water, etc., as they exhibit anomalous electrical conductivity compared to the surrounding media and thus can be identified with ease. In this chapter, the discussion is restricted to four themes – hydrocarbons, geothermal resources, water and mineral. Fair treatment is provided on the global scenario for each item and the use of the methodology with a case study is explained. Detection of hydrocarbons in a most difficult region – sub-basalt – is discussed by considering an example from Gujarat, India. Mapping of geothermal potential is discussed with an example from Korea. A case study of assessment of groundwater potential is provided considering the Parnaiba Basin area in Brazil. Application of 3D modelling is provided for McArthur Basin area, Canada, for exploration of uranium. In the treatment of all these problems, the chapter is mainly focused on the use of natural signals for deep electromagnetic method – magnetotellurics.
