Quantitative characterization of hydrocarbon reservoir using integrated seismic rock physics analysis: an integrated approach using seismic data, seismic rock physics of well-log and core

Abstract

The concept of quantitative reservoir geophysics is relatively new in petroleum reservoir geophysics. This will produce more detailed information than common exploration seismic. To predict the existence of hydrocarbon using seismic wave, usually we use a direct method. The quantitative reservoir needs information from many wells in the area of the geophysical survey, such as: well-log, petrophysics, core-rock samples and even fluid samples from the reservoir. The result of quantitative reservoir characterization is an important step in predicting the reservoir character, especially for predicting facies, porosity distribution and reservoir fluid types. In this paper, we show the steps of quantitative reservoir characterization using a seismic rock physics study in order to tie the seismic wave to reservoir properties. To conduct quantitative reservoir characterization, we should have seismic rock physics data under varying reservoir conditions, such as: overburden pressure as well as pore pressure, pore fluid type and even temperature.
