What is Petrophysics?

Petrophysics is the study of the physical and chemical properties of rocks and their contained fluids. Petrophysical analysis emphasizes the calculation of reservoir storage and deliverability based on lithology, porosity, thickness, fluid saturation, and permeability. It also requires integration of log data with rock data generally in the form of core measurements that can be either routine measurements or special core measurements. The purpose of this association is to calibrate the log derived reservoir parameters to those same parameters measured in the laboratory. When agreement on these parameters is achieved, predictive log based models can be established. These models can then be applied at well locations where cores are not available.
