nowadays one of the most important energy sources is natural gas. by depletion of oil reservoirs in the world, natural gasâ will emerge as the future energy source for human life. one of the major concerns of gas suppliers is being able to supply this source of energy the entire year. this concern intensifies during more consuming seasons of the year when the demand for natural gas increases, r...

This paper reports on a project, conducted jointly between SaskEnergy/Transgas and the University of Regina, which aims at developing an integrated decision support system for the optimization of natural gas pipeline operations. In this integrated approach, both expert systems and operations research techniques are used to model the operations of the gas pipelines. The decision support system c...

Natural gas (NG) is one of the widely used domestic fuels in most of the countries, and because of economical and environmental advantages, its consumption is continuously increasing. As a result, complex piping systems are being installed to transport and distribute the gas for end users. Pipelines carrying NG are a significant source of hazard for their adjacent society. The risk of this haza...

The approval by FERC of a regulated natural gas pipeline’s market-based rate application depends upon the availability of substitute pipelines with sufficient capacity to maintain the current transport price. But how much alternate capacity is enough? Clearly, the price will not increase when alternate pipelines have unsubscribed capacity equal to the capacity of the applicant pipeline, since t...

This paper provides a description of the different databases and various influencing factors in the development of a tool to estimate the failure rate of cross-country pipelines. The databases available cover a number of different materials transported: crude oil and liquid products, and natural gas. The various databases give excellent base data to estimate the likelihood of failures of cross-...

This study explores the concept of new energy infrastructures (in particular gas pipelines) in Eurasia and discusses its implications on future energy systems, gas trade, and the environment. Overall resource availability is not expected to be a real constraint in meeting growing energy demand within the next 100 years, but the geographical concentration of resources is. The expected increase i...
