Second wellbores drilling is one of the perspective ways for gas withdrawal. In article the possibility for realization of well-candidates selection procedure by means of a method of the hierarchy’s analysis is described. Methodical approaches of wells complex estimation and ranging of their separate characteristics according to five-point system is resulted. Estimation is carried out according to influence of each characteristic on efficiency of action.
Key words: designing, second wellbore, gas fields wells, final stage of development
