Biopolymer-based drilling fluids affect data of high-frequency isoparametric induction logging. Highly conductive fluid invaded into drilling-induced flaws produces zones of high resistivity contrasts. Thus the logs acquire new features that never appear in drilling with argillic mud. These effects have been simulated with regard to high resistivity contrasts for the case of flawed borehole walls, and the modeling results were checked against experimental data
