Carbon capture and storage (CCS) is a major opportunity for hydrocarbon producers and wider industries to reduce their emissions.
Pumping CO2 underground for enhanced oil recovery (using pressure to push more oil out of reservoirs) has been a tried and tested technique since the mid‑1990s.
Today, the energy transition can benefit from this proven methodology, not only to capture CO2, but to store it. Locking it away for millennia. So, rather than leaving depleted oil fields empty, they can be used as repositories for CO2. Repurposing reservoirs for CCS in this way can bring circularity to offshore facilities, that otherwise would have been de-commissioned.
But the opportunity is much bigger still. Carbon-intensive onshore industries, such as cement manufacturing, can capture and transport their CO2 from shore to be injected below the seabed.
A key challenge for industry, however, is that current CO2 flow lines from shore are prohibitively expensive or in many cases, not up to the task of handling highly corrosive dense phase CO2.
Our proven infrastructure and knowledge of how to optimize solutions can make CCS viable at scale.
We have decades of experience in developing subsea oil and gas solutions across the globe. Now we can reverse that knowledge – quite literally. Because OneSubsea equipment – including pumps, compressors, trees, FPSO swivels and subsea pressure measurement systems – can all be used to put the CO2 right back in where the oil and gas originated. And our expertise will help ensure it remains there for the long run.
All the building blocks for CCS via CO2 injection are qualified and available. We can bring CO2 from shore via flowlines or connect vessels carrying CO2 barrels to seabed pumps. You can even use existing pipelines for temporary storage of dense phase CO2 before pumping it into reservoirs via existing subsea infrastructure.
We can help operators to extend the life and value of reservoirs by repurposing them and support our customers in their journey to net zero.
The core components of our CCS technology have been operational since the 1990s. And today our full-scale high-pressure CO2 test loop has shown that our equipment, from 6MW pump to flow meters, works at every stage.
Waste companies and oil and gas producers can tap into our subsea processing and material technology expertise to create new commercial opportunities in managing CO2.
Whether via pipeline or vessel, we can take CO2 from designated onshore repositories and inject it into suitable offshore reservoirs.
