The technology of multi-zone hydraulic fracturings in horizontal wells, mainly used in low-productive gas fields of the USA and Canada, is considered. Nine-point, seven-point and five-point systems of horizontal wells layout, and also technologies of completion of such wells are given. The results of application of technology in wells of LUKOIL - Western Siberia LLC fields are presented. The efficiency of the considered technology introduction is marked.
