Some New Progress in the Fields of Computational Petroleum Geology and Others

Numerical simulation in oil\|field exploration and exploitation with computational mathematics and dynamics of fluids in porous media is discussed. The numerical method of nuclear waste disposal contamination, prediction and prevention of sea\|water intrusion and the numerical simulation of transient behavior of semi\|conductor devices are also studied. The mathematical model is the nonlinear convection\|dominated diffusion coupled systems with initial\|boundary value problem. Characteristic finite difference method, characteristic finite element method, fractional step numerical method and its theoretical analysis are mainly dealed with.
