pipelines

A federal judge ruled on 14 June that the environmental review for the Dakota Access pipeline was, in part, inadequate and must be reconsidered, handing tribal opponents of the 1,170-mile pipeline project a key legal victory.

At the 2016 Gulf of Mexico Deepwater Technical Symposium in New Orleans, a presentation discussed the application of sensors and analytics in pipeline integrity management systems.

An experimental study was conducted by use of a 6-in.-inner-diameter facility to analyze three-phase stratified wavy flow in horizontal pipelines.

Use of unmanned aerial vehicles to monitor pipeline networks for theft and other issues is discussed.

Since 2007, an operator in Nigeria has registered a significant increase of oil-spill events caused by sabotage and oil-theft activities. The technology presented here allows detecting and locating leaks taking place at a distance from the sensor of up to 35 km.

Bypass pigging has advantages over conventional approaches. Its application to multi-phase flow with high wax content crude is discussed.

This paper reviews the current methodology for assessing pipeline embedment against field data, in which underprediction of pipeline embedment could be critical to design integrity.

With more wells to check than tools and time to do so, a methodology to predict wells with the highest risk of corrosion was developed.

A simple, practical, and reliable method to detect a gas leak under the conditions of unknown inlet or outlet gas rate, or unknown inlet or outlet pressure, is highly desirable. This paper discusses such a method.

Compressor stations often consume 3-5% of the gas they are transporting as fuel. How to minimize this fuel consumption in an optimal manner is the subject of this paper.
