Porosity, the most important petrophysical parameter for the reservoir characterization, is always considered by geoscientists as the key for hydrocarbon reserves evaluation. So, best reservoir evaluation is strongly depending on porosity estimation. Actually, Probabilistic and Stochastic used models are based on established relationship between porosity and different recorded petrophysical parameters at well; the obtained results are generally acceptable in homogeneous and isotropic reservoirs.


ENAGEO has developed for you a new deterministic solution that provides an answer to all your complaints :
This new solution is based on petrophysical attributes extracted from seismic data
using stratigraphic inversion:
