Abstract
An example of an apparatus is provided. The apparatus includes a magnetic core to be inserted into a borehole to a formation. The apparatus further includes a first coil wound about the magnetic core. In addition, the apparatus includes a first current supply to generate a first current to run through the first coil. Furthermore, the apparatus includes a first controller to control the first current supply. The first controller is to oscillate the first current to generate a magnetic field in the formation. Heat is to be generated in the formation via induction.
Claims19
An apparatus comprising:
- a magnetic core to be inserted into a borehole to a formation;
- a first coil wound about the magnetic core;
- a first current supply to generate a first current to run through the first coil;
- and
- a first controller to control the first current supply, wherein the first controller is to oscillate the first current to generate a magnetic field to penetrate into the formation, and wherein heat is to be generated by inducing eddy currents in electrically conductive components of the formation.
An induction heating system comprising a plurality of apparatuses, wherein a subset of the plurality of apparatuses are arranged parallel to each other, and wherein each apparatus comprises:
- a magnetic core to be inserted into a borehole to a formation;
- a first coil wound about the magnetic core;
- a first current supply to generate a first current to run through the first coil;
- and
- a first controller to control the first current supply, wherein the first controller is to oscillate the first current to generate a magnetic field to penetrate into the formation, and wherein heat is to be generated by inducing eddy currents in electrically conductive components of the formation.
