Oil exploration is high risk and expensive process. Petroleum exploration is the search by Petroleum geologists and geophysicists for Hydrocarbon deposits under the earth surface such as oil and natural gas. Oil seeps, natural gas seeps, pockmarks are the evidences for hydrocarbon generation. Mostly this exploration depends on sophisticated techniques in order to detect the oil deposits by using exploration geophysics. For Large scale survey, hydrocarbons are primarily subjected to gravity survey, magnetic survey, and passive seismic or regional seismic reflection surveys. Elements of Petroleum include Source Rock, Migration, and Reservoir.
