... responses. Several rock physics models have been used to delineate the relations between physical properties (e.g. hydrate saturation, porosity) and elastic properties (e.g. P- and S-wave velocity) for different hydrate microstructural distributions within the sediments. In this study, we propose a 3D...

We account for basin modeling uncertainties by defining prior probability distributions on uncertain parameters and performing Monte Carlo basin simulations. We perform probabilistic calibration of the basin model outputs by defining data...

To shorten the cycle, we designed a simple inversion workflow to estimate reservoir property changes directly from the 4D attribute maps using Machine Learning methods. Thousands of training data sets are generated by Monte Carlo sampling from the rock physics model...
