conductive invasion

1. n. [Formation Evaluation]
A situation in which the resistivity of the flushed zone is less than the resistivity of the undisturbed zone. Such a setting generally favors the use of electrode resistivity devices (laterologs, ring resistivity), which respond to resistivity, rather than induction and propagation resistivity devices, which respond to conductivity.
Antonyms: resistive invasion
