A New Resistivity Logging Method in Production Well

Abstract:

This paper presents a new method for resistivity logging in production well. Based on electromagnetic theory, an electromagnetic response model is established for multi-cylindrical-layer, and the general expressions for through casing electromagnetic logging are deduced. We further calculate and simulate the effects of casing permeability on electromagnetic response and demonstrate the necessity of casing magnetization. Finally, the effectiveness of casing magnetization is validated by the magnetization experiment. The result shows signal penetration capability is significantly enhanced after casing magnetization. It demonstrates that casing magnetization is an effective method for resistivity logging in production well.
