Abstract. Petrophysical properties are a key element for reservoir characterization but also interpreting the results of various geophysical exploration methods or well logs. Furthermore, petrophysical commonly used to populate numerical models and often critically governing model results. Despite common need detailed properties, data still very scarce not available area interest. both online r...

Purpose. The research is aimed at evaluating the petrophysical characteristics of Late Cretaceous Matulla Formation in central part Gulf Suez order to detect its hydrocarbon reservoir potential. Methods. Well logs from five wells (Muzhil-1, -2, -4, -7, -8) were used evaluate reservoirs based on a computerized approach. Petrophysical parameters and fluid types calculated, verified using core dat...

The main purpose of this paper is to further clarify the complexity of the inversion method by using Niche Genetic Algorithms (NGA) to inverse the petrophysical property parameters. The improved BISQ model, presented in our earlier work, is chosen for the forward model in NGA. In this paper, the relationship between the sample number of the given wave response data and the inversion results, su...
