| Abstract: | The theoretical equations on formation resistivity log across casing are presented according to electromagnetic theory. Models for magnetic lines are simulated by numerical method in respect to four frequencies (high,medium, low and extra low frequency).It is shown that the new method using extra low frequency electromagnetic wave to measure the formation resistivity through casing is effective. It provides a theory foundation for the casedhole log interpretation and the development of logging tools. |
