Permeability prediction
WebNov 10, 2024 · The estimation of the formation permeability is considered a vital process in assessing reservoir deliverability. The prediction of such a rock property with the use of the minimum number of inputs is mandatory. In general, porosity and permeability are independent rock petrophysical properties. Despite these observations, theoretical … WebQSPR models are ideal alternatives and have been widely applied to Caco-2 permeability prediction due to their higher efficiency and lower cost. At present, the published QSPR models can mainly be divided into two types: regression models and classification models.
