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 (20) 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.

Abstract: A method for revealing anomalous discontinuity interfaces in pore pressures in non-drilled geological formations and an implementing system. The method includes generating, by an electroacoustic transducer, first pressure sound waves and receiving a reflected signal of such first pressure sound waves generated by at least one discontinuity interface due to passage from first to second different geological formations situated successively along an emission direction of the electroacoustic transducer; calculating speed of the first pressure sound waves generated and distance between the electroacoustic transducer and the at least one discontinuity interface; generating, by the electroacoustic transducer, second pressure sound waves and revealing the electrical impedance induced at terminals of the electroacoustic transducer; estimating, based on the electrical impedance revealed, plural parameters characteristic of the first and second geological formation; estimating pressure of the second geological formation based on the sound speed and distance calculated and the plural characteristic parameters estimated.
