Improved Oil Recovery Department 15 Drouzhba Narodov Str. 628481 Kogalym Russia 2 “LUKOIL-West Siberia” Exploitation experience of West Siberian fields indicates unequal layer generation and premature flooding of recovering production. Imperfection of oil field development at Western Siberia lithologic texture features of productive strata permeability anisotropy – result in initiation of hard recoverable reserves. Owing to this the urgent question is about recovering the hard recoverable oil reserves development of which demands application of untraditional methods.
