| Summary: | The relevance. Oil production at the fields in Perm region is falling, it is necessary to use actively the methods for improving oil recovery. There are many methods, among them: acid treatments, hydraulic fracturing, fracturing, radial drilling. To engage non-drained areas in exploration, the sidetracking, multihole drilling and various types of fracturing are increasingly used now. However, such operations are quite expensive and not always efficient. The technology of radial drilling is a much cheaper alternative to these measures. The method of radial drilling with proper selection of wells-candidates may be very effective. If it is successfully used, it is possible to use non-drainable interlayers, thereby increasing the recoverable reserves. Radial drilling is not effective at all wells, as there are still no clear criteria for its successful application of radial drilling. The analysis of the technology effectiveness with the development of recommendations for use can significantly improve the success of radial drilling. The main aim of research is identification of geological, hydrodynamic and technological parameters for successful application of radial drilling in the fields of Perm region. Object of research is oil-producing wells of the Perm region deposits where radial drilling operations were carried out. Method of the research is based on the use of known methods of mathematical statistics. Results. The authors have analyzed the radial drilling effectiveness in Perm region. A common base for radial drilling was developed. It includes geological, hydrodynamic and technological parameters. The parameters that have the strongest influence on the success of the event are singled out. The authors developed the recommendations for the use of this technology in Perm region.
