Heat Extraction System And Method For Extreme Environments

Abstract: A tool (100) for extracting heat from a reservoir includes a shoe (130) made of a material that withstands temperatures larger than 500 °C, an outer pipe (120) attached to the shoe (130), an inner pipe (110) located within the outer pipe (120) and forming an annulus (112) with the outer pipe (120), the inner pipe (110) having a bore (114), and a flexible connection (140) configured to connect the outer pipe (120) to the shoe (130) so that the outer pipe (120) is allowed to extend and contract without leaking a fluid (154) inside the annulus (112). The inner pipe (110) and the outer pipe (120) are configured to form an uninterrupted loop path (156) for the fluid (154), between a top of the annulus (112) and a top of the bore (114) while also allowing the fluid (154) to directly contact the shoe (130).
