Abstract: The study deals with an approximate numerical method used to resolve non stationary biphasic flow equations emphasising on its prevalence with regard to the other electrical and hydraulic analogy methods. Considering the studied field of inquiry the approximate numerical resolution of the integral or differential equations of the non stationary flow remains the only possible way to determine all the unknown functions such as: y (x,t), z (x,t), Q (x,t).
