Abstract
Determining seismic survey parameters by conventional seismic survey design maybe adequate as far as imaging horizontal layers, or slightly dipping surfaces. In complex structures such as faults, salt domes, and reefs determination of survey parameters is so challenging and critical due to the complicated wave field behavior involved in such structures. In the petroleum industry, detecting faults become crucial for reservoir potential where faults can act as traps for hydrocarbon. Moreover, so as to design better production simulations using hydraulic fracturing, it is important to recognize the faults in shale gas production. In this regard, seismic survey modeling is employed to construct a model close to the real structure, and obtain very realistic synthetic seismic data via seismic modeling. The main objective of this study was to design a proper 3D seismic survey orientation so as to achieve fault zone structures using 2D seismic data, geological reports, and the well information through ray-tracing seismic modeling. The present research indicated that a seismic survey designer is able to ameliorate the image of fault planes in a seismic section by utilizing the proposed modeling and processing approach.
