There is about 0.7 billion tons of high-viscosity oils in Kazakhstan. Development of fields with high-viscosity oils is an urgent task for oil and gas engineers not only in Kazakhstan but also all over the world. This article is concerned with estimation of the efficiency of known in the oil and gas industry technologies aimed at intensifying production and increasing oil recovery in fields with hard-to-recover reserves. One of the types of such technologies is thermal recovery. This paper presents cyclic steam simulation. Estimation of the efficiency of the cyclic steam simulation based on the hydrodynamic model of the East Moldabek deposit of Kenbai filed.</p> <p>As a result of modeling, the current state of field development has been analyzed, reservoir simulation model has been history matched and different production forecast estimations have been made.</p>high-viscosity oilthermal methodssteam injectioncyclic steam treatmentтұтқырлығы жоғары мұнайигерудің жылу әдістерібуды айдауұңғымаларды бумен циклді түрде өңдеувысоковязкие нефтитепловые методы разработкизакачка парапароциклическая обработка скважин1.Анализ разработки уч.
