This series has run over 7 previous articles and has focussed on the key technical distinctions between carbon dioxide storage projects and traditional hydrocarbon production. Read our latest blog, the last in the set, to recap what we have discussed and learn what Merlin has to offer.
Modelling CO2 storage sites presents unique challenges compared to traditional reservoir simulations due to the different timescales the models need to operate over. Read our latest article to learn more.
In this latest blog post, we delve into the role of geomechanics which describes how fluids influence rock behaviour. Continue reading to learn more.
A couple of weeks ago, Bill Wilks attended DEVEX 2024 and was lucky enough to join the conference field trip to the southern coast of the Moray Firth, NW of Aberdeen. Continue reading to read the full article and learn more about the outcrops of fluviatile and aeolian dune sands between Covesea and Burghead, which show sedimentary and tectonic deformation.
Ensuring the integrity of the caprock is paramount for the long-term viability of a Carbon Dioxide storage site. Continue reading to learn more about the challenges of caprock evaluation.
Our Principal Stratigrapher Phil Copestake will be giving the next GESGB evening lecture online on 30th April. Continue reading to find out more about his talk and how to register.
Understanding flow physics is important in modelling the movement of CO₂ underground. Continue reading to learn more about these modelling techniques, focusing on invasion percolation.
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.
