The fluid dynamics of CO₂ differ significantly from those of hydrocarbons due to variations in density, viscosity, and phase behaviour. A nuanced understanding of CO₂ flow physics is imperative for effective modelling and prediction. Continue reading our latest blog to find out more.
Understanding the properties of supercritical CO₂ is pivotal for accurate subsurface modelling. Read our latest blog post to learn more about this unfamiliar phase.
Knowledge gathered from decades of hydrocarbon exploration is vital to help us with our efforts in Carbon Capture and Storage (CCS). However, despite many parallels, there is a significant difference between natural migration of hydrocarbons and the flow of injected CO₂ underground. Robust modelling and simulation of CO₂ plumes is therefore required to fully understand fluid movements to ensure the safe and efficient storage of CO₂. This article looks at these similarities and differences and what it all means for the advancement of CCS going forward.
In her third and final article on rock physics for CCS, Eleanor Oldham discusses the pitfalls of seismic trace modelling for CCS workflows. The article focuses on how fluids are parametrised and how fluid substitution for CO₂ differs from hydrocarbons. Continue reading to learn more.
Following on from last week's blog, Eleanor Oldham continues to discuss the uses of Rock Physics for CCS with her latest article on 4D Seismic and Inversion. Learn about how 4D seismic can be used to visualise the movement of a CO₂ plume through time, how rock physics workflows can be utilised to make sure 4D surveys will be cost effective, and how seismic inversion provides a useful method of relating seismic amplitudes to CO₂ saturations and/or pressure increase.
Rock physics models allow us to characterise rock properties, and, when correctly applied, to de-risk amplitude driven hydrocarbon prospects. Many workers are now bringing rock physics methods to CCS challenges, but what questions can it answer and what limitations do we need to be aware of?

Sedimentology is a key factor in screening for and risking potential reservoirs for carbon storage sites. Having a good understanding of the environment of deposition, heterogeneity within the reservoir and pore-scale sedimentology is key to understanding how injected CO₂ will behave. It is important to make accurate geological models of the fluid pathways to de-risk potential storage units and ensure that the CO₂ we inject will be stored indefinitely.

As the global community intensifies its efforts towards combating climate change, the imperative to achieve Net Zero emissions has never been more pressing. At Merlin Energy Resources Ltd., we are dedicated to supporting this revolution of the energy landscape through pioneering sustainable solutions. Continue reading to see how we are making a difference.
After CO2 emissions are captured (and if they are not utilised), they must be safely stored deep within geological formations and kept there indefinitely with no leakage. This practice prevents the release of CO2 into the atmosphere, helping to safeguard our planet for future generations from the warming effect of this greenhouse gas. Our latest blog explores the key principals that underpin the storage of CO2 and the skills we have at Merlin to assist such projects.
In this series of blogs Merlin is looking into different parts of the CCUS process. This week we turn our thoughts to utilisation of captured carbon dioxide (CO2), where emissions are repurposed for a range of applications rather than releasing them to the atmosphere.
In the pursuit of a sustainable future, Carbon Capture Utilisation and Storage (CCUS) has emerged as a powerful tool in curbing carbon emissions. At the heart of CCUS lies the crucial first step: carbon capture. This process involves the extraction of carbon dioxide (CO2) from industrial processes before it is released into the atmosphere. In this blog, we will explore the various methodologies employed in this essential stage of the CCUS journey.
Carbon dioxide (CO2) is now the most significant greenhouse gas, contributing over 70% of the total effect on climate change as of 2018. During the last decade, there have been many new environmental policies all with large scale reduction of CO2 emissions at their heart. One solution is Carbon Capture Utilisation and Storage (CCUS), a process that holds potential for mitigating the impact of greenhouse gas emissions on our planet.
