More than60 percent of theworld'shydrocarbonreserves isheld bycarbonate reservoirs. Therefore, knowledge of the carbonate reservoir is needed to support the exploration of hydrocarbons. Due tothe complexity ofthe rock structure, carbonaterock physicsresearch arevery limited. In addition, seismic exploration is also required for the search of new hydrocarbon reserves. We then may characterize the reservoir by further processing of the seismic data with seismic inversion. <br /> <br /> <br /> With seismic inversion, physical parameters such as porosity, P-wave velocity, S-wave, and density may be predicted. Many seismic inversion methods are used today, such as acoustic impedance, elastic impedance, and LMR. In this dissertation, we apply one of the elastic impedance method that is the simultaneous inversion to detect gas in sand reservoirs. We will also estimate the Bulk modulus of a rock matrix by expanding the Gassmann model. <br /> <br /> <br /> From seismic inversion, we will obtain the volumes of P-wave velocity, S-wave velocity and density. These volumes is expected to give us a prediction of the gas sand distribution in “Tanah Air” field. The results proved to be correct from a blind well test. <br /> <br /> <br /> Matrix Bulk modulus estimation using the expanded Gassmann model is tested in a carbonate rock core sample. The results are the matrix Bulk modulus of the core sample is 8.39 GPa. These results will further be used as a parameter for fluid substitution.
