Integrated interpretation of well logs and surface seismic

Abstract

Formation properties such as mineral composition, fluid contents, porosity, permeability and etc are accurately obtained from the petrophysical interpretation of well logs. After calibrating the petrophysical interpretation with well testing results, net pay zone is quantified. Different seismic attributes (facies) are associated with different subsurface formation properties in different ways. These distinguished relationships are used to map the areal distribution of formation properties, particularly reservoir fluids. The integrated interpretation of well logs and surface seismic adds value to the process of reservoir optimization. The in-situ measurements of the logs are the ultimate ground truth and are linked to surface seismic via the transformation from logs to seismic waves. This transformation is the vital link to the integrated interpretation of well logs and seismic attributes.
