Abstract
A steam stimulation process for removing viscous hydrocarbonaceous fluids from a reservoir penetrated by a horizontal wellbore. Steam is injected into the wellbore slightly above the reservoir pressure. Injection is continued so as to allow the steam to heat the reservoir by conductance. once thermal-stimulation is obtained to the extent desired, steam injection is stopped and hydrocarbonaceous fluids are produced to the surface. A void is created in the area adjacent the wellbore and hydrocarbonaceous fluids removed therefrom. Steam in an amount sufficient to fill the void is injected into the formation at pressures slightly above the reservoir pressure but below its fracture pressure. Afterwards, the steps are repeated.
