| Abstract |
Several methods for the static reservoir characterization of reservoirs have been implemented in the last 20 years and also different commercial software applications have been developed based on different algorithms. A well accepted system consists of building a model departing from a 3D seismic impedance volume as a spatial background for the distribution of elastic properties and seismic attributes within this cube. Most inverted volumes originate from post-stack inversion. Quantitative interpretation methods are however still at the beginning of their evolution which is really promising and fully dependent on the advancement of future computing capabilities. In this paper a new method for the quantitative analysis, distribution of microproperties with the triple porosity model for carbonate micro properties distribution in the 3D seismic volume is proposed. With this model, one of the key elements for spatial analysis of carbonate is solved in a quantitative way. Porosity partitioning spatial distribution can be regarded as a key theory to predict facies, micro and macro-properties. Microsystems can be distributed through macrosystems in the 3D seismic cube within the pre-stack seismic inversion process. These applications can be related to the sequential processing steps after the seismic inversion and before the implementation of a static model in order to maintain the development of interpretive models strictly quantitative and introduce new constraints to the calculation of micro and macrofield properties. |
