Prediction of Sandstone Porosity Through Quantitative Estimation of its Mechanical Compaction During Lithogenesis (Bibieybat Field, South Caspian Basin)

In this paper a new and easy quantitative approach based on an exponential decrease in intergranular volume as a function of effective stress and incorporated with fuzzy mathematics is suggested for evaluation of the lower limit of sandstones porosity. Furthermore, the comparison of predicted values of sandstones porosity with factual ones allow drawing some conclusions regarding succession of compaction and cementation processes taking place through burial history of rocks.
