Induction Heating - How does it work, and what is it used for?

Web1 jan. 2004 · Induction tools use coils to induce a current and measure the formation's conductivity. These two types of tools have many variations, which are summarized in Table 5.1 . In many cases, it is desirable to use both electrode and induction tools to produce a single resistivity log. WebInduction heating is a reliable and efficient method for heating a wide variety of materials. In this process, heat is generated by the current induced in the component, … WebThe induction log, introduced in the mid-1940s, was designed to measure formation resistivity in boreholes containing nonconductivefluids. Boreholes containing air, freshwater muds, or oil-based muds make excellent environments for induction logging. The induction log actually measures the conductivity of a formation rather than its resistivity. lithium processing flowsheet
