In the right circumstances, CCS and EOR can be linked to sequester significant amounts of CO2 (up to ~100mmscfd / 2 MTA) and extract additional amounts of residual oil (up to ~50mmbo in some places). Finding the right large low BTU reservoir and then locating a large residual oil reservoir […]
Another example of where experience with utilising CO2 injection to facilitate Enhanced Oil Recovery has also helped advance confidence in carbon sequestration technologies and storage integrity monitoring. These combined CCS and EOR solutions continue to scale up with very significant similar but much larger projects being investigated internationally.
Additional confidence in Carbon Capture and Storage solutions can come from the success certain Operators have had with combined solutions of CCS and Enhanced Oil Recovery (EOR). Successfully sequestering CO2 whilst capturing more value with increased recovery from oil reservoirs has allowed these technical solutions to be optimised and demonstrated […]
Another in our series of CCS projects, this one was prepared by Stellae Energy’s Head of Subsurface David Pickering. This project was a good example of combining CCS with EOR. We are going to have more flyers on these kinds of hybrid projects coming up next week.
A number of times various people have said CCS does not work and used the example of Chevron’s Gorgon Project to justify their views. This is uninformed and incorrect – the CCS element of the project worked with carbon capture in the process trains and transportation through pipelines and wells […]
A good informative article by Stellae Energy’s Head of Subsurface David Pickering is reposted here. https://lnkd.in/gKYwVQmt O&G folks aren’t necessarily very familiar with SUPERCRITICAL FLUIDS, but they are an important concept for those working in geothermal / CCS and something with which they need to become comfortable. I have drawn a couple […]
Another type of potential CCS location is depleted oil & gas reservoirs. In these kinds of locations, there would typically be much more data available initially for the technical assessment of the storage capability and any potential integrity issues. Existing well records, production data, and geophysical surveys would be useful […]
The first in a series of posts about successful CCS projects. Deep Saline Aquifers are considered good potential for CCS projects, but substantial subsurface geophysical and geological work is necessary to demonstrate this suitability and long term integrity. One attraction is the fact that these types of aquifers are widespread […]
The East African Rift System is a well known source of Geothermal Energy in Africa, but there is potential for low to medium enthalpy heat resources in more than 25# African countries associated with intrusive plutonic rock formations. Often these locations have been the site of shallow mineral exploration and […]
Another Geothermal Play example is Intrusive Rock as seen in NW Geysers in California. Significant deep heat resources that took some time to fully identify and evaluate in this underdeveloped area. Deepening two exploration wells and running a pilot development helped prove up these resources and open up the location […]
As Europe is facing high electricity costs and energy security issues, there is an economic, environmentally sustainable energy source beneath their feet – persistent Geothermal Energy. In addition to other good prospective locations in Western and Eastern Europe, there are two good basins in Germany – the Upper Rhine Graben […]
