porosity is considered as an important petrophysical parameter in characterizing reservoirs, calculating in-situ oil reserves, and production evaluation. nowadays, using intelligent techniques has become a popular method for porosity estimation. support vector machine (svm) a new intelligent method with a great generalization potential of modeling non-linear relationships has been introduced fo...

The manual picking of reservoir formation boundaries using limited available well-log data in multiple wells across gas and oil reservoirs tends to be subjective unreliable. reasons for this are typically caused by the combined effects spatial boundary complexity availability. Formation characterization classification can improved when treated as a binary task based on two or three recorded wel...

flow unit characterization plays an important role in heterogeneity analysis and reservoir simulation studies. usually, a correct description of the lateral variations of reservoir is associated with uncertainties. from this point of view, the well data alone does not cover reservoir properties. because of large well distances, it is difficult to build the model of a heterogenic reservoir, but ...

accurate permeability estimation has always been a concern in determining flow units, assigning appropriate capillary pressure andrelative permeability curves to reservoir rock types, geological modeling, and dynamic simulation.acoustic method can be used as analternative and effective tool for permeability determination. in this study, a four-step approach is proposed for permeability estimati...

Abstract Facies studies represent a key element of reservoir characterization. In practice, this can be done by making use core and petrophysical data. The high cost difficulties drilling coring operations coupled with the time-intensive nature have led researchers toward using well-log data as an alternative. Teapot Dome Oilfield, where are limited to those from only single well, we used for e...
