Korre A, Durucan S, Shi J, et al., 2013, Development of Key Performance Indicators for CO2 Storage Operability and Efficiency Assessment: Application to the Southern North Sea Rotliegend Group, Energy Procedia, Vol: 37, Pages: 4894-4901, ISSN: 1876-6102
This paper outlines the development of a methodology which can be used to produce key performance indicators for operability and efficiency of a CO2 storage site. The methodology is based on the premise that individual geological formations and their characteristics can be assessed on the basis of their depositional and tectonic setting and more recent reservoir/site history using hydrocarbon exploration and development data. The methodology is illustrated for a candidate storage reservoir in the Rotliegend Leman Sandstone Formation of the UK Southern North Sea.
Govindan R, Korre A, Durucan S, 2013, Application of an Unsupervised Methodology for the Indirect Detection of CO2 Leakages Around the Laacher See in Germany using Remote Sensing Data, Energy Procedia, Vol: 37, Pages: 4057-4064, ISSN: 1876-6102
Remote sensing has demonstrated success in various environmental applications and is considered attractive as it offers cheap and effective wide area monitoring. Recent research efforts, and particularly the development of an unsupervised image processing and indirect detection methodology by the authors, have demonstrated the potential of remote sensing techniques for monitoring CO2 storage sites. This paper describes the application of the methodology at a natural analogue study site around the lake Laacher in Germany using airborne optical remote sensing datasets. The results demonstrate the robustness of the methodology as an indirect technique for CO2 leakage detection.
Shi J, Smith J, Durucan S, et al., 2013, A Coupled Reservoir Simulation-geomechanical Modelling Study of the CO2 Injection-induced Ground Surface Uplift Observed at Krechba, in Salah, Energy Procedia, Vol: 37, Pages: 3719-3726, ISSN: 1876-6102
Building on the previous reservoir simulation study of CO2 injection at Krechba, a coupled reservoir simulation- geomechanical modelling study was carried out, aiming to match the InSAR surface uplift time series at the three injection wells (KB-501, KB-502 and KB-503) over a 5-year injection period (August 2004 - October 2009). The geomechanical response at the ground surface to subsurface CO2 injection has been largely reproduced at KB-501; however mixed results were obtained for areas around KB-502 and KB-503. This work suggests that CO2 has most likely migrated up to the lower caprock around KB-502 from February/March 2006.
Shi J, Imrie C, Sinayuc C, et al., 2013, Snøhvit CO2 Storage Project: Assessment of CO2 Injection Performance Through History Matching of the Injection Well Pressure Over a 32-months Period, Energy Procedia, Vol: 37, Pages: 3267-3274, ISSN: 1876-6102
A performance assessment study of the Snøhvit CO2 project, where approximately 1.1 million tonnes of CO2 have been injected into a fault segment of the Snøhvit field was carried out. Since the start of CO2 injection, the injection well pressure has risen at a rate faster than what is sustainable for a 25-years expected lifetime of the project. An important element of the history matching effort is the incorporation of fluvial facies in the reservoir model to reflect the sedimentary environment in the sandstone Tubåen formation. With the help of 4D seismic analysis, excellent match to both the flowing and shut-in bottom-hole pressure data throughout a 32-months injection period have been obtained. The outcomes of this study suggest that the fluvial depositional environment, together with the fact that the injection well is situated in a fault-segment, have contributed to a significant reduction in the injectivity at F2H.
Nie Z, Korre A, Durucan S, 2013, Full Chain Analysis and Comparison of Gas-Fired Power Plants with Co2 Capture and Storage with Clean Coal Alternatives, Energy Procedia, Vol: 37, Pages: 2840-2847, ISSN: 1876-6102
This paper presents the new models developed for the natural gas fuelled power generation chain, involving various natural gas production methods, gas processing routes, gas transport options, and alternative gas based power generation with/without CO2 capture. The comprehensive and quantitative Life Cycle Inventory (LCI) database developed models inputs/outputs of processes at high level of detail, allowing to account for technical and geographic differences in the power generation value chain scenarios analysed. With the advantage of LCI models developed at unit process level, this work successfully identified the key operational parameters for alternative gas-fuelled power plants and the key component processes that emit the majority of GHGs across the gas supply chains.
Kühn M, Wipki M, Durucan S, et al., 2013, Key Site Abandonment Steps in CO2 Storage, Energy Procedia, Vol: 37, Pages: 4731-4740, ISSN: 1876-6102
The European Commission published a set of Guidance Documents to assist countries and stakeholders to implement the EU Directive 2009/31/EC on geological storage of CO2. The main objectives of the CO2CARE project are closely linked to the three high-level requirements of the Directive with regard to post-closure transfer of liability of a storage site to the relevant competent authority: (i) absence of any detectable leakage, (ii) conformity of actual behaviour of the injected CO2 with the modelled behaviour, and (iii) the storage site is evolving towards a situation of long-term stability. Guidelines for regulatory compliance and “Best Practice” for site abandonment are being established by distillation and integration of all research findings into site closure and abandonment protocols. The work is based on 9 key injection sites in Europe and worldwide.
Syed A, Durucan S, Shi J, et al., 2013, Flue Gas Injection for CO2 Storage and Enhanced Coalbed Methane Recovery: Mixed Gas Sorption and Swelling Characteristics of Coals, Energy Procedia, Vol: 37, Pages: 6738-6745, ISSN: 1876-6102
The impact of coal pore structure on adsorption-induced matrix swelling of three coals of different ranks was investigated experimentally. The swelling strain measurements for the selected samples of the two higher rank coals suggested that variation in the sample pore size distribution, particularly the microporosity, has a larger impact on matrix swelling induced by adsorption of CO2 than by adsorption of less adsorbing gases. The swelling behaviour recorded for the low rank coal may be explained by the level of microporosity or lack of it. From flue gas ECBM point of view, the swelling strain data tentatively suggests that the low rank coal would experience less swelling, compared to the higher rank coals.
Durucan S, Ahsan M, Syed A, et al., 2013, Two Phase Relative Permeability of Gas and Water in Coal for Enhanced Coalbed Methane Recovery and CO2 Storage, Energy Procedia, Vol: 37, Pages: 6730-6737, ISSN: 1876-6102
Gas-water relative permeability behaviour of seven European coals of different ranks was characterised in order to enhance the scientific understanding of the fundamental processes of two-phase flow taking place within the macrostructure of coal. Laboratory experiments were carried out on cylindrical coal samples using the unsteady state method to measure gas-water relative permeabilities due to its operational simplicity. The impact of factors such as wettability, absolute permeability and overburden pressure on coal relative permeability were assessed. Considerable variation in the shapes of the relative permeability curves for different rank coals was observed, which was attributed to the heterogeneous nature of coal.
Smith J, Durucan S, Korre A, et al., 2013, A Methodology to Assess Increased Storage Capacity Provided by Fracture Networks at CO2 Storage Sites: Application to in Salah Storage Site, Energy Procedia, Vol: 37, Pages: 3711-3718, ISSN: 1876-6102
The presence of fractures in the storage reservoir at CO2 storage sites may increase the reservoir permeability and subsequently cause the CO2 plume extent to increase. Similarly, fractures in the caprock could provide regions of secondary storage if CO2 escapes from the reservoir. An important factor influencing the degree of these effects is whether the fractures form a continuously connected, or percolating, pathway. A methodology assessing the existence of percolating network of fractures, which incorporates the uncertainties in measured fracture properties around wells, was applied to assess secondary storage in the lower caprock at the In Salah Storage Site. It is demonstrated that secondary storage will occur if the fracture line density is equal to or greater than 2 m-1 and further shown what length distributions will provide secondary storage, if line density is less than 2 m-1.
Bacci G, Durucan S, Korre A, 2013, Experimental and Numerical Study of the Effects of Halite Scaling on Injectivity and Seal Performance During CO2 Injection in Saline Aquifers, Pages: 3275-3282, ISSN: 1876-6102
Vaporisation of water during dry CO2 injection can cause salt precipitation and lead to significant reduction in injectivity. Research described in this paper aimed at improving the understanding of the halite scaling process through experimental and numerical investigations. Experimental results indicated porosity reductions of about 3 - 5% and permeability reduction between 13 to 75%. Numerical simulation results have shown that halite scaling can have a significant impact on field operations. They also suggested that, salt precipitation can occur at the caprock interface increasing the sealing capacity around the wellbore.

Abstract Fossil fuel-based power generation technologies with and without CO 2 capture offer a number of alternatives, which involve different fuel production and supply, power generation and capture routes with varied energy consumption rates and subsequent environmental impacts. The holistic perspective offered by Life Cycle Assessment (LCA) can help decision makers to quantify the trade-offs inherent in any change to the fuel supply and power production systems and ensure that a reduction in greenhouse gas (GHG) emissions does not result in increases in other environmental impacts. Beside energy and non-energy related GHG releases, LCA also tracks various other environmental emissions, such as solid wastes, toxic substances and common air pollutants, as well as the consumption of resources, such as water, minerals and land use. In this respect, the dynamic LCA model developed at Imperial College incorporates fossil fuel production, transportation, power generation, CO 2 capture, CO 2 conditioning, pipeline transportation and CO 2 injection and storage, and quantifies the environmental impacts at the highest level of detail, allowing for the assessment of technical and geographical differences between the alternative technologies considered. The life cycle inventory (LCI) databases that were developed, model the inputs and outputs of the processes at component or unit process level, rather than ?gate-to-gate? level, and therefore generate reliable LCI data in a consistent and transparent manner, with a clearly arranged and flexible structure for long-term strategic energy system planning and decision-making. The presentation discussed the principles of the LCA models developed and the newly extended models for the natural gas-fired power generation, with alternative CO 2 capture systems. Additionally, the natural gas supply chain LCA models, including offshore platform gas production, gas pipeline transportation, gas processing, lique

Laboratory studies and a number of field pilots have demonstrated that CO2 injection into coal seams has the potential to enhance coalbed methane (CBM) recovery with the added advantage that most of the injected CO2 can be stored permanently in coal. The concept of storing CO2 in geologic formations as a safe and effective greenhouse gas mitigation option requires public and regulatory acceptance. In this context it is important to develop a good understanding of the reservoir performance, uncertainties and the risks that are associated with geological storage. The paper presented refers to the sources of uncertainty involved in CO2 storage performance assessment in coalbed methane reservoirs and demonstrates their significance using extensive digital well log data representing the Manville coals in Alberta, Canada. The spatial variability of the reservoir properties was captured through geostatistical analysis, and sequential Gaussian simulations of these provided multiple realisations for the reservoir simulator inputs. A number of CO2 injection scenarios with variable matrix swelling coefficients were evaluated using a 2D reservoir model and spatially distributed realisations of total net thickness and permeability.
