    Abstract: At present, the mainstream technology for the stimulation of tight reservoir which exists a large number of interlayer is "perforation concentrated & large-scale fracturing". But the fracture simulation and monitoring result indicates that the vertical zone of the reservoir actually isn't stimulated fully. To increase the degree of the reservoir st... Show More

    Abstract: Mathematical model for leak location in natural gas pipeline has been developed in this paper. The model employs an isothermal steady state approach. Leak occurrence in the pipeline divides the pipeline into two sections-the upstream and downstream sections respectively. Analyses of leak incidences were carried out in the two pipeline sections givi... Show More
