pipelines

This paper presents the results of tests conducted to design a fast-breaking gelled fluid for a debris-removal operation in a long, large-diameter subsea pipeline in the Asia Pacific region. where traditional pigging was not an option.

This paper shows that viscosity has a significant influence on gas transient flow in pipe- and tank-leakage evaluation. This led to the development of a methodology for more reliable evaluation of gas transient flow.

The present work describes the development of a 1D steady-state isothermal reservoir/surface gas-pipeline-network model. The developed model is an extension of the general pipeline-network model in which the deliverability from the wells is calculated.

During the design of two parallel gas pipelines from Russia to Germany through the Baltic Sea, major design changes were made to minimize project impacts, resulting in rapid approval by all five affected countries.
