A promising innovation with a ponderous name, pseudo dry gas (PDG), opens the possibility of developing stranded-gas fields in remote locations by making it possible to build far-longer tiebacks and ultimately produce more gas. |
But it comes with a major challenge: convincing offshore producers that they can rely on a subsea system that separates natural gas from the condensate and water in the production stream. |
The benefits are obvious. Being able to move gas and liquids separately is a lot more efficient and avoids problems associated with multiphase flow, particularly slug formation, which requires topsides equipped to catch the slugs. Separation also reduces backpressure, which is expected to increase the ultimate recover... |
In the 4 years since the idea debuted at the Offshore Technology Conference (OTC), a small team in Worley’s Aberdeen office has built and successfully tested a small-scale prototype of a flow loop with the support of an industry partnership including three unnamed energy companies. |
Even with all of that, they needed to establish an added benefit to win a critical government grant to build and test a full-scale prototype for high-pressure testing. This energy-efficient alternative promises to significantly reduce carbon emissions compared to offshore compression and platforms. |
“As the energy industry strives toward sustainability, it’s important to support solutions that enable decarbonization,” said Andy McDonald, head of Low Carbon Transition at Scottish Enterprise, which put up £765,000 ($1 million) to support testing, according to a release from Worley. |
