This study simulates the response of deep and medium resistivity induction logs in fractured carbonate reservoirs using the integral equation numerical technique. We used as a base the Miranda et al. (2009) model, whose laterolog resistivity results were verified using the Cozzolino (2004) finite element algorithm. Using the piston-type mud invasion, our resistivity induction results indicate that when the invasion is 0.5 m, there is nearly no difference between both curves. Still, when the mud intrusion is increased to 1.0 and 1.5 m, a bigger separation between them gets up, which shows a tight link between the invasion and permeability.
