The CarbonNet Project: 3D mapping and correlation of intraformational seals within the Latrobe Group in the nearshore Gippsland Basin
15th October 2015
The Global CCS Institute presents the sixth report published by the CarbonNet Project, located in Victoria, Australia, this report has focussed on a critical aspect of CO2 storage - containment of the CO2. CarbonNet are investigating the potential for establishing a large scale, multi user CCS network bringing together multiple CO2 capture projects, transporting CO2 via a shared pipeline and injecting it deep into an underground, offshore storage site and is currently in feasibility and commercial definition stage.
The Gippsland Basin is known to have a world-class proven regional seal (or caprocks), known as the Lakes Entrance Formation it has stored oil and gas accumulations for tens of millions of years. This regional seal has always been identified as the final barrier to CO2 plume migration in any storage concept in the basin. This report has identified several additional, laterally extensive seals below the regional seal, known as the T2 seal. These additional sealing units are expected to provide an effective barrier to the CO2 injected into the primary storage targets below in the Halibut reservoirs. The T2 seals are proven to be effective containment rocks as they have previously retained oil and gas accumulations locally and nearby. Also, lab measurements on rock samples of the seal suggest they could hold back a column of CO2 in excess of what is expected to be required in the reservoirs below. This investigation has revealed there may be hundreds of gigatonnes of additional storage available and confirms that the Gippsland Basin is a world class storage site for CCS.

The CarbonNet Project: integrity of wells in the near-shore area Gippsland Basin Victoria
14th October 2015
The Global CCS Institute presents this new report by CarbonNet evaluating the impact legacy petroleum wells may have on their search for CO2 storage sites in the nearshore Gippsland Basin. The CarbonNet Project is investigating the potential to establish a CCS Hub bringing together multiple CO2 capture projects in Victoria’s Latrobe Valley, transporting CO2 via a shared pipeline and injecting it into deep saline formations in the nearshore Gippsland Basin.
This report identified and then analysed legacy petroleum wells that may have an impact on the feasibility of CO2 storage sites targeted as future storage concepts. The analysis included using data lodged with the regulatory authority to assess how the legacy petroleum wells were ‘completed’. The investigation found that none of the wells have any significant risk of leakage and that there is negligible risk of CO2 rising to near-surface levels.

The CarbonNet Project: site characterisation for carbon storage in the near shore Gippsland Basin
7th September 2015
The Global CCS Institute presents a carbon dioxide (CO2) storage site characterisation study for the CarbonNet Project. The CarbonNet project is investigating the potential to establish a CCS Hub bringing together multiple CO2 capture projects in Victoria’s Latrobe Valley, transporting CO2 via a shared pipeline and injecting it into the offshore Gippsland Basin. The report details the steps taken during the screening of potential storage sites in the offshore Gippsland Basin.
Three of the highest ranked sites are identified and their geological characteristics detailed and suitability for CO2 storage are described. The report found that all three storage sites are located nearshore and have the potential to dispose of between 25 and 15 Mt of CO2 permanently in deep saline formations.
This report is authored by Nick Hoffman, George Carman, Mohammad Bagheri, Todd Goebel; and the CarbonNet Project for the Global CCS Institute. Chris Consoli, Institute Senior Adviser for Storage, Asia-Pacific also provides an overview of the report in a new Insight available on the Global CCS Institute website.
Relative permeability for multi-phase flow in CO2 storage reservoirs. Part II: resolving fundamental issues and filling data gaps
30th June 2015
This report, prepared for the Global CCS Institute by a consortium of research organisations led by Stanford University, presents an assessment of fundamental issues pertaining to the relative permeability of brine and carbon dioxide (CO2) systems. This research follows an earlier report published by the Institute in August 2013 which provided an overview of this topic and highlighted knowledge gaps.
Relative permeability is an important factor in determining the fate and transport of CO2 over the lifetime of a storage project. To date only limited information on this critical factor has been available, much of which is summarised in the 2013 report. This report addresses key gaps in knowledge and data related to CO2 storage in saline formations.
Strategies for injection of CO2 into carbonate rocks at Hontomin: final technical report
29th June 2015
This is a technical report examining the different strategies used for injection of CO2 into Carbonate Rocks at the Hontomin CO2 Storage Project in North West Spain. The report is authored by the CO2 injection team at CIUDEN (or Fundación Ciudad de la Energía – Spain's publicly funded energy research foundation), in collaboration with the Ground Water Hydrology Group of UPC-CSIC Barcelona.
The report aims to give an overview of current thinking around CO2, carbonate rocks and their interaction, before going into detailed description of the various CO2 injection strategies employed at the Hontomin test injection site.
A summary of the literature on CO2 thermodynamics, and a high level overview of the large volumes of literature on carbonate rocks and their interactions is provided, along with analysis of the performance and interpretation of simulation models and laboratory tests on the dynamics of CO2 injection and storage in carbonate rocks.
The report goes on to describe strategies for CO2 injection into carbonate formations, specifically focusing on:
- Push-pull tests
- Supercritical injection
- Liquid phase injection
- Pulsed (intermittent) injection
For each strategy, the shape and size of the CO2 plume and operational conditions for low permeability formations, are analysed. Mechanical stability issues are also discussed. It is hoped that the publication of these results from the Hontomin test injections, will contribute to the development of key site characterization techniques and the improvement of modelling approaches and field scale tests for evaluation of different CO2 injection strategies.
This report is published in connection with a further technical report from the CIUDEN team in Hontomin - Hontomin Reservoir characterization tests – and to a suite of bilingual community outreach and education initiatives created and delivered in the communities around the Hontomin site before, during and after construction of the injection site.
Hontomin Reservoir characterisation tests: final technical report
29th June 2015
This is a technical report cataloguing the reservoir characterisation techniques emerging from the Hontomin CO2 Storage Project in North West Spain. The report is authored by the CO2 injection team at CIUDEN (or Fundación Ciudad de la Energía - Spain's publicly funded energy research foundation), in collaboration with the Ground Water Hydrology Group of UPC-CSIC Barcelona.
Building on existing research into CO2 injection into low permeability carbonates for enhanced oil recovery (CO2 -EOR) operations in North America, the Hontomin site provides an opportunity in Europe to develop injection and CO2 storage-related activities in a low permeability, carbonate deep saline aquifer. This novel approach for dedicated geological storage could provide learnings for potential storage operations in other sites of low permeability.

Aquistore: CO2 storage at the world’s first integrated CCS project. Project summary report
18th May 2015
The Global CCS Institute commissioned the Petroleum Technology Research Centre (PTRC) in 2013 to provide a summary report on the Aquistore project, a CO2 geological storage site located near the town of Estevan in southern Saskatchewan, Canada. Aquistore will be used by owner/operator SaskPower as a dedicated geological storage option for CO2 captured from the nearby Boundary Dam Power Station - the location of the world’s first commercial scale post-combustion capture of CO2 from coal fired power generation.
