An apparatus and method for analyzing the continuous flow of drilling cuttings in real time on a surface while drilling employs a set of sensors placed around an analyzer tube and main auger or within the main auger related to the formation with a defined space-time shift. The method includes measuring the sample to obtain specific properties related to physical and petrophysical parameters of this formation (radiation, resistivity, inductivity, density, elasticity, others). Obtained signals are conditioned and digitized in order to derive the desired discrimination in target properties, such as rock type, porosity, density, and oil saturation. An expanding auger, with a hollow end adapted to receive a sensor tube in which the sensors or sources may be placed, is adapted to rotate or circulate a discrete media about the sensors.
