Electromagnetic heating apparatus for underground hydrocarbon formations
The patent US12071837B2 describes an innovative apparatus designed for the electromagnetic heating of underground hydrocarbon formations. The apparatus consists of two or more wellbore casings that extend from the ground surface to the hydrocarbon formation, with each casing having distinct proximal and distal portions. A key feature is the electrical connections established between the proximal portions for grounding and between the distal portions to create a short circuit, which minimizes current flow to the surface. This second electrical connection is strategically located at a junction where the wellbores are in close proximity, allowing for efficient thermal management and energy transfer.
Additionally, the patent outlines methods for constructing these wellbores, including drilling and casing procedures. The method emphasizes the importance of the spatial relationship between the wellbores, particularly at the junction where their longitudinal axes intersect. Techniques such as enlarging the upper wellbore to connect with the lower wellbore, and the use of electrically conductive materials and fasteners, are also detailed. These methods aim to enhance the conductivity and stability of the connections, ensuring effective electromagnetic heating of the hydrocarbon formation. The patent thus presents a comprehensive approach to improving the efficiency of hydrocarbon extraction through advanced electromagnetic heating techniques.
