    Heavy oil is a type of petroleum that is different from conventional petroleum insofar as it is much more difficult to recover from the subsurface reservoir. It has a much higher viscosity than conventional petroleum, and recovery of this petroleum type usually requires thermal stimulation of the reservoir. This study presents results of analysis of influence of thermal methods like Steam Assisted Gravity Drainage (SAGD) and Cyclic Steam Stimulation (CSS) in the one of heavy oil fields in Karpaty mountains. Numerical simulation was used for investigation of thermal EOR influence on recovery. Application of horizontal and vertical wells was analyzed. Variable volume of injected steam and different stages time steps were used. Results of analyses scenarios suggests that quantity of injected steam and length of injection cycles has large influence on oil recovery.
