摘要： A computer-implemented method of providing access to interferometric system data stored in a data repository. A query that includes a data parameter identifier is received. The data repository is accessed and the interferometric system data is stored in the data repository using a data structure that has one or more data parameter arrays and one or more corresponding data group members. Each data group member includes one or more data arrays each associated with a data parameter in the corresponding data parameter array. Using the data parameter identifier, one or more target data parameters are determined from among the one or more data parameter arrays. One or more target data arrays that correspond to the one or more target data parameters are determined from among the one or more data arrays. The interferometric system data, which is in the one or more target data arrays, is extracted.

摘要： There is provided a method of estimating flowrate in a pipeline based on acoustic behaviour of the pipe. First acoustic data is measured from the pipeline. A flowrate of the fluid in the pipeline is then estimated. The estimation is based on the first acoustic data and based on a correlation established between second acoustic data and corresponding flowrate data from an experimental pipeline. The correlation is established by a machine learning process (which may include the use of an artificial neural network, such as an autoencoder). The second acoustic data and corresponding flowrate data are used as inputs to the machine learning process.

摘要： Methods and systems for estimating a distance between an acoustic sensor and an acoustic reflector in a conduit are disclosed. One such method includes using the acoustic sensor to measure a combined acoustic signal that comprises an originating acoustic signal propagating along the conduit and an echo signal. The echo signal is generated by the originating acoustic signal reflecting off the acoustic reflector after propagating past the acoustic sensor. A frequency domain representation of the combined acoustic signal is determined and the echo signal is identified by identifying in the frequency domain representation periodic oscillations having a peak-to-peak difference between 0.75Hz and 1500Hz. The distance between the acoustic sensor and the acoustic reflector is determined from the velocity of the echo signal and a time required for the echo signal to propagate between the acoustic sensor and the acoustic reflector.

摘要： There is described a method of determining a position of a pipeline inspection gauge (PIG) in a fluid conduit. While the PIG is moving through the fluid conduit, one or more sensors positioned along the fluid conduit are used to detect one or more signals. Parameter data is extracted from the detected one or more signals. The parameter data includes one or more parameters of the detected one or more signals as a function of time and position along the fluid conduit. PIG movement data indicative of a position of the PIG in the fluid conduit as a function of time is generated using the parameter data.

摘要： There are described methods, systems, and computer-readable media for detecting events in a conduit. Multiple lengths of optical fiber positioned alongside a conduit are used to detect a signal. For each length of optical fiber, interferometric data is obtained from the detected signal. The interferometric data obtained for one length of optical fiber is compared to the interferometric data obtained for one or more other lengths of optical fiber. Based on the comparison, it is determined whether the signal originated from the conduit.

摘要： A sound baffle device for use with an acoustic sensor deployed in a housing by a deployment line is disclosed. The sound baffle device comprises a radially extending baffle plate and an affixing mechanism for affixing the baffle plate to the deployment line. The baffle plate is configured to reduce acoustic transmission between a first zone of the housing on one side of the baffle plate and a second zone of the housing on an opposite side of the baffle plate. A system for detecting acoustic signals in a zone of interest in a housing is also disclosed. The system comprises an acoustic sensor positioned in the zone of interest and one or more than one sound baffle positioned between the zone of interest and a first zone of the housing. The sound baffle is configured to reduce acoustic transmission from the first zone to the zone of interest. The sound baffle provides some level of acoustic isolation between two zones on either side of the baffle plate thereby aiding detection and identification of acoustic signals in the zone of interest by reducing transmission of acoustic signals from the first zone to the zone of interest.
