This will be the final print issue of Oil and Gas Facilities. It is becoming an online-only publication. While the format in which you read the magazine will change, nearly everything else remains the same. It opens up a number of exciting new possibilities for us to serve you better with more frequent delivery of content in a web-friendly format that is easier to read and enables faster downloads.
As operators look to reduce the on-site development time and cost for projects, they have begun adopting a modular approach to facility design, moving construction away from project sites and to the fabrication yards. While this approach may provide some benefit, it may not be the most efficient path to take.
A case study illustrates how an inadequate sizing methodology hinders gas scrubber performance. The causes of excessive carry-over that contaminated downstream equipment are identified and a potential solution is presented for revamping the vessel. The benefits of using a more consistent design methodology are highlighted with the final equipment configuration, the estimated carry-over, and flow distribution through the vessel based on computational fluid dynamics.
The failure rate of capital-intensive megaprojects remains high when evaluated by cost overruns, schedule delays, and operational problems. Many of these project train wrecks are self-inflicted; seldom are they caused by a bolt out of the blue. Five major factors that can lead to failure are discussed.
Mature Oilfield Facilities Enhancement: Use of Two-Screw Multiphase Pumps To Stimulate Increased Well Production
In maturing oil wells, oil production is often restricted as reservoir pressure depletes and well backpressure from surface facilities remains the same or increases. Two case studies highlight the application of two-screw multiphase pump systems in the Caspian Sea and onshore Mexico to mechanically lower well backpressure, resulting in increases in oil production and extension of well life.

An experimental study investigates the characteristics of three-phase stratified wavy flow in horizontal pipelines under low-liquid-loading conditions. The flow characteristics include wave pattern, liquid and water holdup, pressure gradient, and wetted-wall fraction.
