Abstract (en)
[origin: EP3124739A1] A steam producing apparatus (13) is used for forcibly moving contaminants build up on the wall of the well (11) and to open up the fractures to allow the flow of oil into the well. Steam is generated in a structure that is lowered into the well and to apply pressurize steam onto the well wall and against the fractured areas to release oil and to allow oil to flow more freely, thereby producing more oil. The pressure of the produced steam can be regulated within the structure lowered into the well. It can also be monitored from the surface.
