Controlled Source Electromagnetic (CSEM) is a new technique used for hydrocarbons detection. This study focuses on One dimension (ID) modeling of hydrocarbon detection for onshore application using the principles of electromagnetic (EM) waves propagation. The transmitted frequency which is 0.25 Hz was used to characterize the hydrocarbon at 500 m, 1000 m and 1500 m. Electric fields detected by the receivers at 500, 1000 and 1500 m were 22.85, 20.4 and 17.1 V m-1, respectively which was determined by using ID simulation. This non-seismic ID modeling may provide alternative solution for hydrocarbon (HC) detection for oil and gas industry. © 2011 Asian Network for Scientific Information.
