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 CO2 storage resource. To help understand the challenges faced by different countries that have ei...

Review of CO2 Storage in Basalts

​Review of CO2 storage in basalts – new technical review from IEAGHG on the potential of using basalts and other magnesium rich rocks to store CO2. Conventional CO2 storage relies on injection into a reservoir in sedimentary rock which has an impermeable caprock. It is also possible to trap CO2 in igneous rock formations with high magnesium, iron a...

The Kemper County Energy Facility

One of the latest CCS projects to begin operating in the United States is the Kemper County Energy Facility in the state of Mississippi. Richard Espoito, the Geosciences, Carbon Utilization and Storage Southern Company, programme manager, presented an up-beat account at the start of the GHGHT-13 conference on Thursday. Richard stressed the modern '...

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 CO2 into a saline aquifer at one point and then extract heat energy from another location within the same aquifer. Doublet extraction and injection of cool...

Quest one year on

The GHGT-13 plenary session on Wednesday 16th November opened with an upbeat assessment of the Quest CO2 storage demonstration site in the Canadian province of Alberta. Tim Wiwchar, who is Shell Canada's Portfolio Manager Heavy Oil, presented a summary of the progress since this flagship project started operating in November 2015. Quest was built o...

Advances in wellbore integrity

 CO2 storage relies on the injection of the gas either via pre-existing wellbores or, in the future, new wells. CO2 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 G...

Pressure Testing Experiment at the Swiss Mont Terri Rock Laboratory

 The Swiss are making an important commitment to long-term CO2 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 Opalinu...

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 CO2 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 exc...

New IEAGHG Report: 2016-13 Fault Permeability

Fault zones are widely recognised as being important to the secure long term storage of CO2 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 CO2...

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

 The use of CO2 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 CO2-EOR in other mature petroleum producing regions. If CO2-EOR could be implemented it would offer an economic stimulus to develop CO2 storage. There are, ho...

Risk Management Network and Environment Research Network Combined Meeting Concludes

 The summary report of the Risk Management Network and Environmental Research Network Combined meeting held in September 2015 has now been published. This meeting was held at the UK's National Oceanography Centre (NOC), in Southampton and was attended by 62 delegates from 11 countries. The three day meeting included themes on risk assessment m...

Operational flexibility of CO2 transport and storage

 One of the advantages of CCS as a means of CO2 abatement is that several industrial processes, as well as fossil fuel power generation, can be captured and connected to a pipeline network. Multiple sources of CO2 can then be transported to suitable geological reservoirs and injected to ensure secure storage. Many industrial operations, and po...

Evaluation of Barriers to National CO2 Geological Storage Assessments

 A study recently completed for the Carbon Sequestration Leadership Forum (CSLF) has just been published. This review was undertaken by the CO2 Storage team of the British Geological Survey (BGS) on behalf of UK Department of Energy and Climate Change and the Korean Clean Energy Ministry who jointly funded the work. The project was managed by ...
