With the improvement of the seismic characterization chain (processing, inversion, lithoseismic classifications), even more detailed facies cubes are obtained and used for mapping precisely still a wide range of heterogeneities inside reservoirs models. This paper describes how the evolution of techniques and methods since 2000, on a deep offshore turbidites field of Angola, improved year after year the description of reservoir properties in the field reservoir model. It represents a quick experience feedback comparing methods and evaluating pros and cons.
