... compositions, the dynamic network simulation combined with forecasting of behavior all sources and offtakes, is necessary. The article describes model of full chain of calculation. At entries, there are: productions, storages and interconnectors with more less stable gas compositions and LNG Terminals where...

... Abstract With the Visual Storage Scheduler one can visually schedule the usage of supply and storage's in a winter period. Winter will be passed through with monthly steps. For each month there is a Load Duration Curve (LDC). Deliverability of storage is dependent on used working volume, which...

... is higher than maximum supply in winter and vice versa in summer. To overcome these differences Gasunie has got the possibility to use underground storage as a balance-tool. Gas supplies have different gas qualities. Consequently this means that gas has got different qualities all over the network. At some...

... Corporation (TCO) operates over 12,500 miles of Storage and Transmission pipeline in the North Eastern part of the U.S. The primary supply is from Columbia Gulf Transmission in Kentucky with deliveries in the states of WV, KY, OH, PA, VA, MD, NY, NJ, DE, NC and DC. We operate 140 compressor stations...

... and transmits it through the pipeline system to the 13 LDZs and to a number of very large loads, mainly power stations. Gas is also input to the high pressure system from salt cavity storage and LNG sites at a number of locations. At various points on the NTS there are pipeline junctions consisting of pipework...

... ABSTRACT Optimization scenarios for integrated storage systems can be completed quickly and efficiently by utilizing a variable state modeling technique. This technique uses consecutive steady state analyses to simulate flow from storage pools and through transmission pipelines to demonstrate...

... simulation, in its own right, has evolved over some time with a more recent focus being seen on the numerical modeling of gas storage reservoirs. This paper will present the general aspects of gas storage reservoir simulation with an emphasis on the behavior of reservoirs under such conditions as dictated...

... of unbundling Texas Gas's supply, pipeline and storage capacity are described, including some of the dificulties encountered. Texas Gas's eforts to work interactively with their customers during the various stages of the compliance process are also discussed 1 INTRODUCTION Order 636 requires natural gas...

... through reduced operating costs with lower internal roughness (drag) and reduced fouling. Internal coating offers protection against corrosion caused by atmospheric oxidation during storage and the presence of corrosive components in the transported material. Coated pipes are also easier to inspect...

... INTRODUCTION Union Gas with 485,000 customers is Canada's second largest distributor of natural gas. Union's franchise area in southwestern Ontario encompasses 10,965 square miles in which we operate a production, transmission, distribution and storage operation. With 93 BCF of developed...
