Abstract
A method for estimating an anomalous pore pressure value at depth level of a first discontinuous interface between a first geological formation and a second geological formation to be drilled by means of a drilling apparatus comprising at least one bit, where said method is implemented by means of a system comprising at least one electro-acoustic transducer () mounted with said bit, at least one memory for containing observable data and at least one control processor for processing observable data contained in said at least one memory, where said at least one processor controls transmitting a signal transmitted at a given frequency, said at least one electro-acoustic transducer receives a received signal that said at least one processor records in said at least one memory, comparing it with pre-loaded observable data in said at least one memory and estimating the value of the anomalous pore pressure of the first discontinuous interface.
