Abstract: Various embodiments provide a method of simulating a leak in a pipeline. The method includes: receiving a fluid stream from a fluid supply; and outputting the received fluid stream through an outlet such that the received fluid stream hits an outer surface of the pipeline at a location opposite the outlet such that a vibration is caused in the pipeline. Some other embodiments provide a corresponding system for simulating a leak in a pipeline, and a corresponding outlet for coupling a conduit to a pipeline.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Methods, systems, and techniques for simulating an event. Simulated event data comprising a simulated event, and authentic raw data, are both obtained. The simulated event data and the authentic raw data are blended to form blended data that comprises the simulated event. The blended data may be fed into an event detection system, such as a pipeline leak detection system, for testing purposes.

Abstract: 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.

Abstract: There is described a method for interrogating optical fiber comprising fiber Bragg gratings (“FBGs”), using an optical fiber interrogator. The method comprises (a) generating an initial light pulse from phase coherent light emitted from a light source, wherein the initial light pulse is generated by modulating the intensity of the light; (b) splitting the initial light pulse into a pair of light pulses; (c) causing one of the light pulses to be delayed relative to the other of the light pulses; (d) transmitting the light pulses along the optical fiber; (e) receiving reflections of the light pulses off the FBGs; and (f) determining whether an optical path length between the FBGs has changed from an interference pattern resulting from the reflections of the light pulses.

Abstract: There is provided a system for determining multiple baselines for detecting events in a conduit. The system comprises an optical fiber interrogator for interrogating optical fiber; and one or more processors communicative with the optical fiber interrogator and memory having stored thereon computer program code configured, when executed by the one or more processors, to cause the one or more processors to perform a method. The method comprises, for each of multiple channels of the conduit, each channel comprising a portion of the conduit: obtaining phase data for the channel, the phase data being obtained by causing the optical fiber interrogator to interrogate optical fiber positioned alongside the conduit; and determining one or more baselines from the phase data. As a result, events in the conduit may be detected with fewer false positives.

Abstract: Described are methods and systems using optical fiber interferometry to sense interference causing events in a region of interest and differentiate between a strain event and a thermal event. Other methods and systems relate to the use of optical fiber interferometry for determining temperature offset in a region of interest and using the determined temperature offset for determining temperature in the region of interest.
