This Study has been conducted from MirMir area which is located in Block 5A (As per Su- dan oil concession map) in the Republic of South Sudan (RoSS). Variability in environment and terrains results in using different type of sources which is produces different seismic features not representing the real information from the subsurface, as always it must be there is only one changeable factor indicating the subsurface geology. The main objective of this study is to generate 3D seismic data for MirMir area from two types of energy source and to compare between the dynamite and Vibroseis as seismic sources. These objectives have been achieved by using methodologies to unify the acquired and processed data to correct for that idle case. As a result of this work this field is a produc- ing field now.Geophysics
