The Japanese company ratcheted up the competitive nature of contracting for a floating production, storage, and offloading vessel and an onshore liquefied natural gas plant for the Abadi project by announcing dual front-end engineering design (FEED) contracts.
Work by researchers at the University of Saskatchewan aims to advance the understanding of clathrate hydrates, crystal cages of ice that can trap gas and liquids.
Electricity produced onshore powers oil production at Johan Sverdrup holding CO₂ emissions at only 5% of the global average.

This paper considers some of the challenges and learnings associated with the application of chemicals for preservation of coated pipe/flowline for a major liquefied-natural-gas (LNG) project in Australia. -
Gazprom’s third pipeline to course through the Arctic further decreases Russia’s dependence on using Eastern European countries as thoroughfares to export its gas to markets in Western Europe.

The understanding of solid-particle flow regimes in pipelines for any operational conditions is important for identifying the nature of particle interaction and movement. In this paper, a comprehensive analysis of solid-particle flow regimes in stratified flow in a horizontal pipeline is presented.

The downturn and lack of investment for new projects are likely to impact the onshore pipeline industry toward the end of the decade. But the long-term drivers for pipeline construction, notably the increased demand for gas in regions such as Asia, remain stable.

A study using a dynamic multiphase-flow software simulated a rapid-unloading event and determined the gas fraction in the riser annulus and the effect on riser fluid levels.

This paper describes the qualification process for a thermoplastic composite pipe manufactured for use in high-performance riser, jumper-spool, and intervention-line applications.
-
Natural-gas-infrastructure reliability is critical for the energy sector. When capitalizing on old pipelines to transport natural gas, operators run the risk of partial blockage. In this study, the authors develop a multirate test method to detect partial blockage in a gas pipeline.
-
This paper describes a new direct electrical heating method in flexible-pipe systems. The method effectively expands the operational envelope of flexible unbonded pipes with greater control of hydrate plugs and wax precipitation by distributed heating along the entire pipe length,

Thermoplastic composite pipe (TCP) is a spoolable, fully bonded pipe with glass or carbon-fiber reinforcements. While most often used in deep water, the combination of a solid wall, spoolability, and corrosion resistance makes TCP attractive for production-flowlines in shallow water also.

Subsea processing is an evolving technology in ultradeepwater development and has the potential to unlock a significant amount of hydrocarbon resources. In this paper, the authors have reviewed the application of subsea systems in 12 deepwater fields and discussed the significance of each.
