The electromagnetic method is one of the important approaches to hydrocarbon prospecting. In an approach to invert resistivity and induced polarization (IP) using the constraints of seismic and electric logging data, the accuracy of reservoir-distribution prediction on the formation's electrical properties is improved. An example illustrates that a joint interpretation workflow of electromagnetic properties (resistivity and polarization), for seismic traps as well as seismic attributes, can significantly reduce drilling risks for oil and gas exploration. The number of practical projects also supports the conclusion. Joint interpretation works at different stages of oil and gas exploration and production with positive results.
