Water saturation modeling using modified J-function constrained by rock typing method in bioclastic limestone

Oil & Gas Science and Technology, 2020
Combining both geological and petrophysical properties, a reliable rock typing scheme can be achieved. Two steps are included in rock typing. Step 1: rocks are classified into lithofacies based on core observations and thin sections; Step 2: lithofacies ...

Estimation Of Lithologies And Depositional Facies From Wireline Logs [PDF]

, 1999
We approach the problem of identifying facies from well logs though the use of neural networks that perform vector quantization of input data by competitive learning. The method can be used in either an unsupervised or supervised manner.
