Abstract: A monitoring system of the integrity of a pressurised pipe by at least one pressure pulses generator that is hydraulically connected to the fluid in the pipe. Each generator comprises: one first tank and a second tank that maintain the fluid respectively at a first and a second pressure values. The first value is smaller, and the second value is greater than the predefined pressure value of the fluid in the pipe. The first and second tanks generate respectively a negative pressure pulse, caused by the passage of the fluid from the pipe to the first tank, and a positive pressure pulse, caused by the passage of the fluid from the second tank to the pipe. A pressure transducer is designed to measure the pressure values of the fluid in the pipe and to convert the negative or positive pressure pulses generate by the generator into respective recorded acoustic signals. A measurement station is placed along the pipe to detect the acoustic signals.

Abstract: A description is given of a system and a method of monitoring of a pipe for the transportation of a fluid at a predefined pressure value. The system comprises at least one pressure pulses generator device hydraulically connected to the fluid transported by the pipe. Each pressure pulses generator device comprises at least one first tank, designed to contain fluid coming from the pipe and to maintain it at a first pressure value which is smaller than the predefined pressure of the fluid transported by the pipe, and at least one second tank, designed to contain fluid coming from the pipe and to maintain it at a second pressure value which is greater than the predefined pressure value of the fluid transported by the pipe. The first tank and the second tank generate respectively a negative pressure pulse, caused by the passage of fluid from the pipe to the first tank, and a positive pressure pulse, caused by the passage of fluid from the second tank to the pipe.

Abstract: A system and method remotely measure in real time through sound waves, geometric parameters of a pipeline in the launch step. An acoustic transceiver positioned in a pipeline includes an acoustic transmitter emitting an input acoustic signal into the pipeline, based on an electric pilot signal. An acoustic receiver detects the input acoustic signal and generates a first electric measurement signal, dependent on the input acoustic signal. The acoustic receiver receives an input return signal dependent on the input acoustic signal and on pipeline geometric parameters, and generates a second electric measurement signal based on the return acoustic signal. A control unit generates an electric pilot signal and connects to the acoustic transceiver and receives the first electric measurement signal and the second electric measurement signal. The control unit measures the geometric parameters of the pipeline based on the first and second electric measurement signals.

Abstract: A method and a system remotely detect the position of a pig device inside a pipeline for transporting pressurized fluids, like for example long distance oil and gas pipelines having a strategic international value. The method foresees equipping the pipeline with pressure sensors in contact with the fluid, located at at least one of the two terminals of the pipeline, and the sending and processing of signals by a control unit. The operation of the system is that of identifying and locating, in real time and continuously, a pig device that moves intermittently inside the pipeline, for example during cleaning, monitoring, measurement and non-destructive control operations.

Abstract: To perform inversion based on electromagnetic (EM) data acquired in a subterranean survey, time domain controlled source EM (TD-CSEM) data is acquired by at least one EM receiver in response to EM signals from a controlled EM source. Further data is received, where the further data is selected from among magnetotelluric (MT) data and DC data acquired by the at least one receiver. A probabilistic joint inversion is applied on the TD-CSEM data and the further data to produce a model representing a subterranean structure that is a target of the subterranean survey.
