It spans a wide spectrum of applications in the oil industry, crossing many discipline boundaries such as geophysics, geology, petrophysics and reservoir engineering. It is complemented by several tutorial chapters on fuzzy logic, neural networks and genetic algorithms and geostatistics to introduce these concepts to the uninitiated. The application areas include prediction of reservoir properties (porosity, sand thicDevelopments in petroleum science ;51.PetroleumProspectingData processingHydrocarbon reservoirsComputer simulationSoft computingPetroleumProspectingData processing.Hydrocarbon reservoirsComputer simulation.Soft computing.622/.18282/0285Nikravesh Masoud1959-1825429Aminzadeh Fred1342851Zadeh Lotfi Asker1975MiAaPQMiAaPQMiAaPQBOOK9911006643403321Soft computing and intelligent data analysis in oil exploration4393101UNINA01338nam0 22003011i 450 UON0025915020231205103705.4120041126d1953 |0itac50 baspaES||||e |||||Diccionario de literatura española[directores de la edición Germán Bleiberg y Julián Maríascon la colaboración de Jesús Manuel Alda Tesán ... et al.]2a edMadridRevista de Occidente1953XIII, 926 p.23 cm.001UON002591522001 Diccionarios de la Revista de Occidente210 MadridRevista de OccidenteLetteratura spagnolaEnciclopedie e dizionariUONC055341FIESMadridUONL000218860.03Letteratura spagnola.
