Improving petrophysical interpretation through statistical log analysis and rock physics modeling

Abstract

Uncertainties in the quantitative interpretation of well log data are often unquantified and ignored. Uncertainties are always present to some degree and have many underlying causes such as quality of log data, lack of calibration data, choice of petrophysical model, choice of model parameters. Understanding the nature of reducing the uncertainties is important if the petrophysical results are to be used for reservoir characterisation, reservoir modelling or risk analysis.
