Technical inefficiency and productive decline in the U.S. interstate natural gas pipeline industry under the Natural Gas Policy Act

Optimization Models in The Natural Gas Industry

With the surge of the global energy demand, natural gas plays an increasingly important role in the global energy market. To meet the demand, optimization techniques have been widely used in the natural gas industry, and yielded a lot of promising results. In this chapter, we give a detailed discussion of optimization models in the natural gas industry with the focus on the natural gas producti...

Evaluating and Enhancing Competition in the Interstate Natural Gas Transportation Industry

In 1996, the Federal Energy Regulatory Commission (FERC) established criteria it uses when evaluating proposals for marketbased rates by natural gas pipelines. Since that time, a number of significant developments have occurred, both in markets for natural gas transportation and in economic tools for marketpower assessment. This article will review the current approach for measuring interstate ...

Natural Gas Compressor Stations on the Interstate Pipeline Network: Developments Since 1996

This special report looks at the use of natural gas pipeline compressor stations on the interstate natural gas pipeline network that serves the lower 48 States. It examines the compression facilities added over the past 10 years and how the expansions have supported pipeline capacity growth intended to meet the increasing demand for natural gas. Questions or comments on the contents of this art...

Risk-shifting, and Natural Gas Pipeline Regulation

Experimental Study of the Residual Stresses in Girth Weld of Natural Gas Transmission Pipeline

In order to achieve integrated condition in the girth welding of high pressure natural gas transmission pipelines, the weld zones and its surrounding area should have good mechanical properties. Residual stresses are an important defect especially in the girth welding of the pipeline. In this study, two API X70 steel pipes (with spiral seam weld) of 56 inches outside diameter and 0.780 inch wal...
