Well test analysis of Horizontal and deviated wells inrnthe presence off cross –flow phenomenon and no uniformrndepletion Application to a field case : Hassi-Messaoudrnoil field AlgeriarnInformation that one can get from the well testrnanalysis of non conventional wells are very important.rnThis allows us to investiguate parameters that can not bernestimated from vertical wells, indeed the interpretationrnof non conventional well tests in heterogeneousrnreservoirs, needs to take into account differentrnphenomena affecting directly fluid flow.
