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 Pre-stack seismic inversion is an effective method to estimate multiparameter from reflection data in the oil–gas reservoir exploration. In order get a reliable inverted parameter result, constrained model commonly used reduce multi-solution inversion. However, it hard appropriate by conventional well-log interpolation or velocity field offshore exploration with sparse wells. Envelope ...

The nature of empirical allometric expressions relating dispositional and kinetic parameters for a given xenobiotic across multiple mammalian species is well known. It has also been demonstrated that a simple allometric relationship may be used to predict kinetic parameters for humans based merely on data for multiple xenobiotics from rats. We decided to explore reasons for the variance in the ...

in order to meet the significantly increased metal demand of the world market, it has been decided to expand the capacity of the existing alumina refineries and to set up new plants (more than 2 mt/a each). the selection among the bauxite sources is based on previous exploration data, such as: tonnage, grade, mineralogy, etc., the geographical position of the deposit, existing natural and const...

In general, the conventional approach to structure study uses potential-field data, including aeromagnetic and gravity data, for detecting the basement structures, and geophysical well-log data (combined with seismic data when available) for interpreting the sedimentary cover structures. With respect to well-log data, the main approach is to interpret faults from isopach and structure-top conto...
