In this study, three shallow reflection seismic techniques known as CMP, optimum window and optimum offset were investigated in order to image the overburden-bedrock surface, which depth is comprised between 30 and 60m. The research was carried out to estimate the quality of the subsurface image for each one of the techniques in terms of cost concerning data acquisition and processing. Variations for the existing techniques have been proposed to reduce the cost of the acquiring data without deteriorating the resolution of the method. The methodology of the proposed research consists basically of four steps which are: (1) executing field tests to determine the acquiring parameters that best fit the investigated area; (2) planning and executing the seismic survey including all the investigated techniques; (3) selecting, sorting and processing the seismic records
