Abstract: An object moving along a conduit having multiple channels is tracked. Each channel defines a portion of a length of the conduit. For each channel, acoustic data, generated from one or more acoustic signals detected at the channel in response to movement of the object along the conduit, is generated. For at least one channel, the acoustic data obtained for the at least one channel is cross-correlated with the acoustic data obtained for at least one other one of the channels. Based on the cross-correlating, a position of the object within the conduit is determined.

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: 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.
