Abstract: Method and device for detecting and/or measuring at least one geophysical parameter from a core sample (1), in particular in the oil sector, comprising, during an operation of core drilling with a sampler (2); arranging, substantially fixed relative to the sampler (2), a sensor (3) for detecting and/or measuring said parameter, directly downstream of the exit orifice (5) of the sampler (2) relative to the direction of withdrawal of the core sample (1), in the vicinity of the withdrawal path of the core sample (1), detecting and/or measuring values of the parameter at at least one location on the core sample (1) while the latter is being withdrawn from and/or moved back in the sampler (2), and processing of the detected and/or measured values of the parameter, in order to store them in memory and/or use them immediately.
