In classical steam assisted gravity drainage (SAGD) processes for in situ extraction of carbon-containing materials, vapor is introduced into the reservoir at a high pressure, requiring a comparatively great technical effort. According to the invention, condensed water is used that is introduced into the reservoir via an injection pipe (101, 106, 107) and is horizontally conducted inside the pipe within the reservoir such that the water can evaporate in situ and the heat can be applied to the reservoir. This results in a significantly simplified technical installation. In particular, there is no need to desalinate the water at great expense as in prior art.
