Technology innovation that can enhance the monitoring of CO2 in the subsurface explained at the US DOE Carbon Storage Meeting

The US DOE annual Carbon Storage Review meeting, held in Pittsburgh 1-3 August, included presentations on the latest technology innovations currently under development in the country. One of the challenges of secure subsurface storage is the ability to track CO 2 in deep reservoirs. Fibre-optic distributed acoustic sensors (DAS) are attracting incr...

CCS Measuring, Monitoring & Verification (MMV) – Engagement Day, NOC, Southampton 17th July 2017

  Secure retention of CO 2 in offshore storage sites will depend on reliable measuring, monitoring and verification (MMV) to ensure that any unplanned releases can be detected. The marine environment also needs to be characterised so that potential changes caused by a release of CO 2 can be distinguished from natural variability. The Energy Te...

2016-TR6 National CO2 Storage Assessment Guidance

  The effectiveness of CCS as a global solution to carbon emission abatement will depend on widespread deployment in both established industrialised and developing economies. One of the key stages for any country is the identification of a national CO 2 storage resource. To help understand the challenges faced by different countries that have ...

Review of CO2 Storage in Basalts

​ Review of CO 2 storage in basalts – new technical review from IEAGHG on the potential of using basalts and other magnesium rich rocks to store CO 2 . Conventional CO 2 storage relies on injection into a reservoir in sedimentary rock which has an impermeable caprock. It is also possible to trap CO 2 in igneous rock formations with high magnesium, ...

Combining CCS and Geothermal

One of the themes covered by GHGT-13 in Lausanne is the potential of combining CCS and geothermal energy. There are different ways in which geothermal energy might be used. One idea is to inject CO 2 into a saline aquifer at one point and then extract heat energy from another location within the same aquifer. Doublet extraction and injection of coo...

Advances in wellbore integrity

 CO 2 storage relies on the injection of the gas either via pre-existing wellbores or, in the future, new wells. CO 2 is potentially corrosive and in certain conditions can induce rapid cooling. Both conditions are detrimental to wellbores so it's important to understand how these conditions occur and what mitigation options are available. The...

Pressure Testing Experiment at the Swiss Mont Terri Rock Laboratory

  The Swiss are making an important commitment to long-term CO 2 storage through international collaboration and research. This is notably evident at the Mont Terri Rock Laboratory situated in the Jura Mountains about two hours drive north of Lausanne. This facility has been deliberately constructed within an impermeable shale called the Opali...

The use of natural analogues to study patterns of CO2 migration.

 The geomechanics session at GHGT-13 in Lausanne has covered a variety of topics including the value of studying natural analogues. Useful insights into CO 2 migration within formations can be gained especially where fractures provide natural conduits for geochemical alteration. Exposures of the Jurassic Entrada formation in Utah provide an ex...

New IEAGHG Report: 2016-13 Fault Permeability

Fault zones are widely recognised as being important to the secure long term storage of CO 2 as they could provide a leakage pathway out of the target reservoir. Fault characterisation within reservoirs, especially where they extend into caprock, and other overlying formations, needs to be thoroughly understood as part of any risk assessment for CO...

Regional Assessments of the Economic Barriers to CO2 Enhanced Oil Recovery in the North Sea, Russia and GCC States

  The use of CO 2 for enhanced oil recovery (EOR) is a well established commercial practice in the United States where it has been used for over 40 years. There is widespread potential for CO 2 -EOR in other mature petroleum producing regions. If CO 2 -EOR could be implemented it would offer an economic stimulus to develop CO 2 storage. There ...
