Meeting regulatory requirements – in uncertain geology, how do you conduct a site characterisation?

At the Site Characterisation session of GHGT-13, Nick Hoffman demonstrated how the CarbonNet project managed to design their plume mapping approach to successfully meet regulatory requirements. A prediction of plume paths with more than a 10% probability of occurrence are required by Australian GHG storage regulations. The probabilistic modelling a...

GHGT-13 Student Reception

The GHGT-13 Student Reception, sponsored by G.E, was held last night, Wednesday 16th November, and began with a welcome from Sian Twinning (IEAGHG). Sian emphasised how beneficial the reception is to all attendees, as it enables students to meet and discuss what they have heard and learnt at GHGT-13 with their peers. It also allows then to connect ...

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...

20 years of monitoring CO2 storage at Sleipner

Statoil have been operating at Sleipner since 1996 marking twenty years of injection monitoring at the site. The monitoring programme has been shown to be a success proving both conformance and containment as well as including contingency plans. Repeated seismic and gravimetric surveys have been conducted throughout the lifetime of the project alon...

Residual Trapping – what happens after CO2 injection?

 A total of 10 talks discussing trapping mechanisms for CO2 were presented at GHGT-13 on Tuesday. This included new research from Stanford University (Charlotte Garing et al.) which demonstrated, through micro-CT imaging experiments, the residual trapping effects that occur at pore-scale within the reservoir (and the impact of capillary pressu...

Calculating CO2 storage resource – which way is the right way?

As part of the Risk Assessment session held at GHGT-13, Scott Frailey from the Illinois State Geological Survey spoke about the issues surrounding the variety of techniques currently used to calculate storage resource and their associated uncertainties. He announced that The Society of Petroleum Engineers CCS Technical Section is forming a multi‐so...

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...

Opening Speech GHGT-13 Kelly Thambimuthu

 As I spoke to open GHGT-13 today COP22 is underway in Marrakech. It is worth reflecting on the historic agreement that was made at the preceding COP21 meeting held in Paris last year. Paris set us the added aspiration of a new global temperature target of below 20C, even though we are working towards a 20C target. We know very well that even ...

IEAGHG 50th ExCo

The 50th bi-annual IEAGHG ExCo meeting has come to a close in the beautiful Swiss city of Lausanne. The two day IEAGHG Executive Committee meeting began on Saturday 12th November and was held in the excellent Hôtel de la Paix. This regular meeting is held twice yearly, at different locations across the world each time, and gives IEAGHG an opportuni...

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...

“Keep calm and carry on” - COP-22 underway, with CCS events, and American developments.

COP-22 got underway in Marrakesh in unseasonable heavy rain. Several thousand delegates are gathering at the tented city that is the conference centre for the work to start developing the implementation details of the Paris Agreement, in terms of frameworks, processes and mechanisms. Negotiations commenced under SBSTA on the Technology Framework in...

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...

New IEAGHG report: Evaluation of process control strategies for normal, flexible and upset operation conditions of CO2 post combustion capture processes

 It is important for power plants to be able to operate flexibly to respond to changes in consumer demand for electricity. Flexibility is also becoming increasingly important due to the greater use of other low carbon generation technologies, particularly variable renewable generators. The issue of operating flexibility of power plants with ca...

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...

Visit to Tomakomai Project

 During the CSLF week of meetings in Tokyo, the Japanese hosts RITE and JCCS Company arranged for a day visit to the Tomakomai project on the northern island of Hokkaido. This project is capturing CO2 from a gas stream from the hydrogen production unit at the Tomakomai refinery using a unique two-stage pressure swing absorption system, and inj...

Paris Agreement Enters into Force.

The Paris Agreement has now entered into force. To date 74 countries have joined the agreement, 55 were needed. These countries represent 58.83% of global greenhouse emissions, breaking the required 55% threshold. That was the easy bit, now the hard work starts, there a big hill to climb to get to below 2 degree C temperature rise.
