Drilling well process present the first practical step in petroleum industry, which prepared by geophysical and geological surveying.
The rentability of oil industry is relied to the quality and strength of well construction, where the drilling process is characterized by their high cost because the large consummation of chemical and metallic materials. This cost increase with the augmentation of the problems occur during drilling. The success degree of well drilling is evaluated by the low cost and the effect on the target formation.
We study the phenomena of mud filtration due to the importance of the exchangeable effect between drilling mud and borehole; and the necessary to understand the mechanism of mud filtration. The practical importance of this study shown as a key to treat the problems of drilling well process.
Recently, simulation and modeling are used to decrease the mud drilling problems as borehole stability and the sidewall pollution, and achieve the best possible rentability. This method provides predictive capacity help us to better understanding of mud filtration mechanism. By the suitable input data, we can solve the
calibrated mathematical model analytically or numerically. We present in this research the formulation of mathematical model of static and dynamic mud filtration.
