ABSTRACT:
Methods of directly analyzing wireline well logging data to derive pore types, pore volumes and capillary pressure curves from the wireline logs are disclosed. A trained and validated neural network is applied to wireline log data on porosity, bulk density and shallow, medium and deep conductivity to derive synthetic pore type proportions as a function of depth. These synthetic data are then applied through a derived and validated capillary pressure curve data model to derive pore volume and pressure data as a function of borehole depth.
