ABSTRACT:
The present invention pertains to a process for detecting leaks in a pipeline when the flow is in a transient or steady condition. A mathematical model of the pipeline is constructed and real pressures and real flows are compared at various locations in the pipeline with predicted pressures and flows of the model at such locations. Leaks in the pipeline are indicated when upstream of the leak real pressure decreases and real flow increases with respect to the model and downstream of the leak real pressure decreases and real flow decreases with respect to the model.
