Potential for Geothermal, CCS, EOR/EGR, and Energy Storage End of life, depleted hydrocarbon, porous formations, either sedimentary or naturally fractured systems, are valuable assets with existing data and infrastructure potentially able to be repurposed for hybrid redevelopments. Additional value is able to be investigated and captured with potential combinations of […]

The next CCS example in SE Asia to be discussed is the BP Tangguh project in Indonesia. A giant depleted gas reservoir is planned for carbon sequestration along with Enhanced Gas Recovery (EGR). Significant CO2 emissions from the LNG facilities will be captured and injected into the nearby Vorwata reservoir.
Some very good projects are being developed in South East Asia involving high CO2 gas reservoirs and the use of Carbon Capture and Storage of these potential emissions in nearby depleted gas reservoirs. The first example is Repsol’s Sakakemang project in Sumatra Indonesia.
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 […]
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 […]
There are good technologies to capture Carbon and tens of thousands of suitable subsurface locations for Storage. With the continued use of carbon based energy sources and processes during our Energy Transition, we should be rapidly scaling up CCS.
In a number of locations, there may be an opportunity to combine two technical solutions: Carbon Capture and Storage (CCS) and Geothermal Energy development. Carbon storage in either sedimentary or mafic/ultramafic formations may sometimes be combined with circulation of fluids to obtain heat for Geothermal electricity prior to reinjection of […]
