Week 13 : logs and production data

Production data analysis methods include empirical and analytical techniques. Empirical techniques fit a curve to production data, while analytical techniques match a physical model to production data. An empirical technique is a decline curve analysis, and analytical techniques include analytical aquifer models,pressure transient test models, and material balance. Semi-analytic techniques combine empirical relationships and physical models. Empirical techniques are widely used to prepare reserves estimates and yield information that can help differentiate between reservoir realizations.
