==Rock-log calibration==

In most basins, few intervals in only a small number of wells are cored. Thus, calibrating of rock information (from continuous cores, closely spaced sidewall cores, or cuttings) to wireline log responses is essential to interpretation of depositional environments from logs alone. (For details of correlating cores to logs, see the chapters on “Preprocessing of Logging Data” in Part 4 and “Core-Log Transformations and Porosity-[[Permeability]] Relationships” in Part 5. For information on interpreting depositional environments from logs, see the chapter on “Lithology from Logs” in Part 4.)
