Abstract

The behaviors of low-resistivity annular in the front of invasion were studied using fluid-flowing theory and petrophysics equations when fresh-water mud was used during drilling. For porous and permeable formations, mud cake permeability controls the invasion rate mainly. Greater values of formation porosity decreased the movement rate of the annular. Formation permeability hardly affects the behaviors of the annular. The present results provide physical understand for the low-resistivity annular.
