Therefore, this work presents an innovative machine-learning (ML) workflow using convolutional neural networks (CNNs) for the estimation of residual oil saturation ( S or ) based on the generation of partitioning tracer responses in heterogeneous media. To train the CNN model a Python-based...

The test has historically been used to estimate residual oil saturation (Sorw) after waterflooding between injector-producer pairs when the oil is essentially immobile. During polymer flooding, especially with viscous oil, additional oil is displaced and traditional means...
