In this method by using seismic attributes, petrophysical parameters are obtained along a seismic section. First of all seismic attributes are extracted from the trace passing the wellbore and used as input of neural network; petrophysical parameters measured along the wellbore are used as output of neural network. The network has been trained by mentioned input and output and seismic attributes has been extracted from each of the traces along the seismic section. By applying them to the network, respected petrophysical parameters has been estimated along the seismic line.
