This paper presents a new method to prognosticate underground fluid. This method is based on 3-D seismic imaging analysis and so-called dynamic channel tracing. It includes two main steps. The first step is to construct a pseudo-permeability model of the region investigated, and the second one is to trace the underground fluid flow channel with maximal flux. The pseudo-permeability model is constructed according to the rock fractures detection results based on 3-D seismic amplitude data analysis. The maximal flux channel is determined based on a supposition that it has minimum resistance. The fluid flow channel tracing is carried out by introducing an imaginary source and an imaginary collection. The paper describes the discrete configuration for the fluid flow dynamic channel tracing and two numerical tests. The tests show that the idea and the related algorithms present in this paper are valid.
