520 _aThe well logs available in the La Peña and Tundy fields have been logged for different service companies from the 60ś (the oldest wells) up to the present time. The logging tool generations go from the oldest (Neutron in cps, Density gamma gamma, Microlog, Resistivity) to the modern technology (PI, CDL, CN, NMR, etc). This wide variety of logging tools technology made the normalization a critical step before getting into any Petrophysical Evaluation. Some logs corrections such as depth shift, wrong values corrections and eliminations, SP base line and others, were also applied before normalization. The main task of normalization was to obtain an homogeneous log data set because an important number of log traces showed signs of differing calibration and scaling. This became most apparent when the logs were displayed in cross sections and also when cross plots were compared with each other for different wells. This publication shows the importance, benefits and follows the log normalization procedure applied to 79 wells from La Peña field and the 9 wells from Tundy field. Once log normalization was performed, the wireline log data base obtained was consistent and homogeneous which let us count with reliable results in the petrophysical evaluation.
