The studies of the combined method of CHOPS and Cycling Steam Stimulation (CSS) of high viscosity oil reservoirs are described. Technological efficiency of the said stimulation compared with the traditional CSS shown and the main factors that influence the said process determined.

The methods aimed at simulating the non-isothermal multi-phase fluid flow in a formation with wormholes within dual porosity/dual permeability model with parameters expressed as a coordinate function equivalent to the average parameters of the fractal structure described.
