0183;A newly emerging microbiological soil stabilization method, known as microbially induced calcite precipitation (MICP), has been tested for geotechnical engineering applications. MICP is a promising technique that utilizes the metabolic pathways of bacteria to form calcite precipitation throughout the soil matrix, leading to an increase in soil strength and stiffness.In shale and calcite rich sands,the existence of calcareous components makes the resistivity of sand increase,the existence of shaly components makes the resistivity of sand decrease.These characteristics make it very difficult to quantify water saturation.On the basis of review on relationship of reservoir quality index versus porosity,it is feasible by slope value of double
