Abstract: When drilling for oil and gas there are different physical and chemical processes. This is the result of the impact of drilling mud with rocks. This can be diffusion, filtration, heat transfer, capillary flow, etc. Filtration is one of the most important processes that affect drilling operations. It affects the absorption of drilling fluid, the manifestation of fluids, the formation of clay cake on the walls of the hole and the emergence of other phenomena. When calling the influx phenomenon can be observed that determine the quality and efficiency of injection wells. To create and scientifically justify methods to achieve the results of improving the efficiency of opening oil and gas reservoirs which can prevent various complications, you need to own set of rules, laws and dependencies on the basis of which the movement of gases and liquids in the formations. This study is the object of the theory of filtration.
