Abstract (en)

The invention relates to method for producing hydrocarbons from a multilayer system, and an apparatus for use in such a method. The multilayer system comprises at least one high permeable layer and at least one low permeable layer, wherein the high permeable layer is adjacent to the low permeable layer, wherein a first injectant is injected into the high permeable layer and simultaneously a second injectant is injected into the low permeable layer, wherein oil replaced by the first and second injectants from the high and low permeable layers is collected, wherein the rate of injection of injectants for the high and low permeable layers is monitored and adjusted to keep the fronts of displacement of oil from the high and low permeable layers within predetermined limits.
