Oil and gas is at present the most important energy fuel in the world. Consumption of these resources has reached huge dimensions forcing companies to explore more and more potential sources of hydrocarbon reservoir.The established approaches for predicting reservoir fluids can be time-consuming and inaccurate. This paper describes the application of multifractal analysis on seismograms for delineation of reservoir fluids. Preliminary results show that the multifractal analysis on seismograms is able to delineate the reservoir fluids effectively. The sets of holder exponents and the singularity spectrum showed that each reservoir fluid exhibits a unique value of singularity strength and spectrum. Effective delineation is an important step that will improve performance of oil and gas industry by reducing drilling uncertainties. More accurate seismic data processing and interpretation would help reservoir engineers to make a better decision concerning production plans.
