One of the principal challenges of enhancing efficiency of production and injection wells is improving permeability of collector formations. The main changes of collection properties take place in the bore zone of the formation and are connected with the well construction and operation, which brings about a reduction in recipience of injection wells and flow of production ones. The oil production industry of the recent years has seen employment of various techniques of heat treating the bore zone of the formation to boost oil recovery. One of such techniques involves a high-frequency induction exposure. However, theoretical fundamentals of the application of the induction impact are practically non-existent at present, and no assessments of the induction heating efficiency have been made to compare it to other kinds of heat applications. The paper presents the results of mathematically modeling the process of an induction impact upon the formation. It investigates regularities of the formation of a resulting thermal field. Also presented in the paper is the efficiency of the induction heating of the formation versus heating using electric (resistance) heaters. It has been demonstrated that the use of an induction heater brings about an increase in the heating depth and a reduction of the duration of bore zone treatment by the factor of five or six if compared with using an electric resistance heater. The paper exhibits some results of experimental and methodological works on the use of induction treatment, as well as some examples of a geophysical support of the process of treating the formation bore zone.
