This paper describes the operator’s digital-twin end-to-end production system deployed for model-based surveillance and optimization.
The authors of this paper describe a project to develop a virtual sensor to monitor the cooling effect downstream of a subsea choke to avoid hydrate plugs during cold-start operations.
First LNG at Tellurian’ asset known as Driftwood LNG before Woodside’s acquisition last year is expected in 2029.

The technology described by the authors provides the simplicity of a single-step distillation process for the separation of CO2 from natural gas. The technology has shown the potential to separate CO2 and other impurities from natural gas more efficiently and more cost-effectively. -
An underperforming scrubber that was suffering from too much oil carry-over is described along with options for debottlenecking and improving performance.
-
Efficient separation assumes uniform flow, but the reality of inlet geometries can invalidate this assumption, leading to separation problems and loss of separation efficiency.
-
Some internals components affect a separator's gas- and liquid-handling capability because of their effects on the liquid level. In this article, the interdependency of cyclonic inlets, cyclonic mist eliminators, and liquid level is highlighted.
-
The paper presents and discusses a solution for immersive training of industrial operators that allows experiencing the multifaceted scenarios of real-plant operations.
-
The sizing procedure described in the paper allows one to size horizontal gas/liquid separators considering nonstable flow rate at the inlet or fluctuations in the liquid fraction on the same stream.
-
High H2S and CO2 content in natural gas pose significant challenges to processing equipment. This article explores the challenges of sulfur removal and high pressures in the presence of acid gas.
-
A project spearheaded by ExxonMobil, Shell, Chevron, and the Southwest Research Institute (SwRI) has been established to advance separation technology through improved testing methods and collaboration between users and suppliers.
-
The world's first full-scale subsea gas compression system is the final stages of construction and is on schedule to be installed in the Åsgard gas field offshore Norway by year's end.
-
The discrepancy between crude and natural gas prices and estimates of increasing natural gas reserves are driving companies to study small-scale gas-to-liquids plants that can tie in multiple sources or stranded gas for a greater profit.
