“…Ates et al (1998) and Wen et al (1998) modified an existing optimization algorithm developed for single-phase reservoir characterization, so as it could be apply to multi-phase reservoirs, and then applied it to a field characterization. Barman et al (2000) and Ouence (2000) examined the relationship between the fracture and the parameters that affected it, using an artificial neural network for the characterization of the fracture reservoir.…”
