Shallow-lying oil deposits are mainly concentrated in the Cretaceous horizons, in the western region of the country, along the Caspian coast. One of them is a highly viscous oil reservoir, consisting of 3 Cretaceous horizons of the Moldabek Vostochny section of Kenbai field, where 54.5 million tons of oil are concentrated, of which 19.5 million tons are recoverable. The current produced reserves makes up 5% of the initial recoverable reserves, and the approved design oil recovery factor implies the full-scale application of thermal oil recovery enhancement methods. The aim of this work is to select the most suitable method of thermal impact and assess the prospects for implementation with the calculation of economic feasibility. Taking into account the geological features of the reservoir, the cyclic treatment of the wells was chosen as the optimal method for increasing oil recovery. According to the results of calculations on the hydrodynamic model, the starting production rates using the technology of steam-cyclic treatment of producing wells are 23 times higher than the production rates for cold production: the difference in accumulated&lt;br /&gt;production over 5 years will be 2030%.&lt;/p&gt;</abstract><kwd-group xml:lang="en"><kwd>high-viscosity oil</kwd><kwd>oil field development</kwd><kwd>enhanced oil recovery</kwd><kwd>thermal methods of EOR</kwd><kwd>steam injection</kwd><kwd>cyclic steam stimulation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>высоковязкая нефть</kwd><kwd>разработка нефтяных месторождений</kwd><kwd>повышение нефтеотдачи пластов</kwd><kwd>тепловые методы воздействия</kwd><kwd>закачка пара</kwd><kwd>пароциклическая обработка скважин</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Фаган М.
