Key words: gas and water-gas stimulation, oil reservoir, methane and water fringe, multiple contact process, oil and gas mutual solubility.
The results of the filtration studies of water-gas stimulation and the mutual solubility in the PVT vessel, supporting the realization of the multi-contact process at the injection of dry gas into an oil reservoir in relation to the light oil of YuK10 layer of Talinskaya area of Krasnoleninskoye field are presented. It is shown, that injection of methane or alternating volumes of methane and water in the reservoir model at the additional displacement of residual oil forms at the front of displacement hydrocarbon "condensate", mainly containing oil light components. Such hydrocarbon liquid is well dissolved in the residual oil, altering its properties, that leads to an effective additional oil displacement from the watered formation.
