The above workflow represent the process through which well logs such as Gamma Ray, Density, Sonic, SP and Resistivity are estimated for 3D seismic attributes.

Using ISI's workflow shown above, all available information such as Depth, Latitude, Longitude, and 3D seismic attributes are used along with some relevant geostatistical data in order to estimate well logs for all locations in the reservoir. This workflow lets you log a well, before drilling it.
