In the area of the Mangystau oilfields a severe deficit of potable and technical water exists. The reserves of the underground waters may play a significant role in its elimination. The prospecting works have been carried out there since 1960-s and a substantial reserves are discovered, which however are used in a very insufficient volume The principal cause of such situation is related to design of the water supply wells, whose total output does not meet the existing needs. In the presented paper the specifics of the principal methods of water supply wells are considered as related to the Samskoye underground water field. The focus is made upon drilling the large diameter wells with reverse flush fluid circulation, which is popular in western countries. The adduced materials are substantiating the significant advantage of that method in volume and quality of the produced water, as well as in the life period of the water supply wells. The paper demonstrates, that under the local conditions the advantages of the method can reveal themselves especially intensely, while its shortcomings would tell in minimal degree. Study of the peculiarities of the main methods of drilling water intake wells; study of hydrogeological conditions of the Sama area. Critical analysis of the main ways of turning is applicable to the Samsk region; justification of the choice of the most effective method of drilling. The benefits of the circulatory system with a reverse wash over other methods of treatment can be considered proven. It provides a sharp increase in the coefficient of use of local resources of underground water, which is the main problem of local water supply to underground water. The need for a wide range of this method is obvious.
