“…Although, a large volume of heterogeneous rocks accepts the injected CO 2 due to disperse flow paths (Ambrose et al, 2008), high heterogeneity in the porethroat size distribution affects the CO 2 distribution and flooding processes (Wei et al, 2014). Therefore, slow and lateral movements of CO 2 in the storage medium is crucial to enhance the chance of immobilization in a low permeability medium (Shi and Durucan, 2009;Teletzke and Lu, 2013). On the other hand, a fast movement of CO 2 plum in the absence of any barriers in the storage medium can alter the wettability due to the pressure build up, and reduces the breakthrough capillary efficiency of the seal during a long-term contact (Chalbaud et al, 2010).…”

Carbon dioxide released into the atmosphere due to anthropogenic activities has raised the alarm of global warming in the near future. CO 2 storage in suitable subsurface geologic media has, therefore, been triggered in recent years. However, identification of suitable sites to store a large quantity of CO 2 for a long period of time is not an easy and straightforward task. Although, a general criterion has already been presented based on local-scale projects in which depth, permeability, porosity, density and containment factors were considered for selection of an appropriate geologic medium, there are many other preliminary factors linked to the storage capacity, injectivity, trapping mechanisms, and containment which should not be neglected during a CO 2 storage site selection. The aim of this paper is to propose a new screening criterion for the CO 2 storage site selection based on a group of key parameters including reservoir and well types, classes of minerals, residual gas saturations, subsurface conditions, rock types, wettability, properties of CO 2 , and sealing potentials. These parameters were combined with those factors presented earlier by other scholars to provide a good insight into the suitable selection of storage sites. Although attempts were made to consider the whole parameters linked to a site selection, more studies are still required to get a final conclusion about the effective parameters which should be a part of the analysis.

“…Published applications of RTM on production timescales are growing with expanded modelling efforts related to CO 2 sequestration and EOR (Wilkinson et al 2010;Stewart et al 2013;Teletzke & Lu 2013). Advances that link model results to observations in the subsurface offer support for the ability of RTM modelling to simulate trends in chemical data from enhanced oil recovery projects involving CO 2 injection into carbonate reservoirs (Holubnyak et al 2011;Shevalier et al 2012).…”

“…Even with the advances above, it is important to consider the most effective way to use the results from various modelling efforts (Teletzke & Lu 2013;Xiao et al 2013). Results are being used increasingly to steer broad insights to diagenetic processes and to provide first-order guidelines for scenarios in the subsurface.…”

The introduction reviews topics relevant to the fundamental controls on fluid flow in carbonate reservoirs and to the prediction of reservoir performance. The review provides research and industry contexts for papers in this volume only. A discussion of global context and frameworks emphasizes the value yet to be captured from compare and contrast studies. Multidisciplinary efforts highlight the importance of greater integration of sedimentology, diagenesis and structural geology. Developments in analytical and experimental methods, stimulated by advances in the materials sciences, support new insights into fundamental (pore-scale) processes in carbonate rocks. Subsurface imaging methods relevant to the delineation of heterogeneities in carbonates highlight techniques that serve to decrease the gap between seismically resolvable features and well-scale measurements. Methods to fuse geological information across scales are advancing through multiscale integration and proxies. A surge in computational power over the last two decades has been accompanied by developments in computational methods and algorithms. Developments related to visualization and data interaction support stronger geoscience-engineering collaborations. High-resolution and real-time monitoring of the subsurface are driving novel sensing capabilities and growing interest in data mining and analytics. Together, these offer an exciting opportunity to learn more about the fundamental fluid-flow processes in carbonate reservoirs at the interwell scale.

“…These uncertainties can for instance be related to parameters in the geological description and material properties. Teletzke and Lu [108] highlight key topics in modeling of the different stages of a CO 2 storage project; from initial screening and selection of potential sites through to development planning, implementation and operation and finally to site closure and post-injection monitoring. The level of required details in the models will change as the project moves through the various phases, expressing the need for different fit-forpurpose models.…”

It has truly been an interesting journey and period of my life from the initial spark of an idea of doing a PhD, to formulating the application and description of my topic, writing papers and presentations, and finally completing this thesis. I consider myself lucky for getting this opportunity to stimulate my general curiosity and there are several people I would like to acknowledge and thank for their contributions to this PhD-event in various ways. First, I want to express my gratitude to my two supervisors, Prof. Jan M. Nordbotten and Dr. Joonsang Park. I highly appreciate our discussions which have always been fruitful and insightful. It is comforting to know you have someone to ask that will push you in the right direction.Going back a few years, to my pre-PhD time, I was employed by NGI (Oslo, NO) that encourages and supports their employees to continuously develop, both personally and professionally, to acquire new knowledge, including studying for a PhD while still being employed. I had recently started looking into CO 2 storage (there is something oddly satisfying about watching a numerical solution of CO 2 migrate through a porous medium) but there were many things related to the physical processes and the equations behind them that I did not understand, yet. I knew that a PhD-study would give me the opportunity to really delve into and explore this interesting topic, and it was Simon A. Mathias at Durham University (UK) that kick-started the process by asking if I ever considered doing a PhD. Together we formulated the initial description of my PhD-plan and I eventually spent about 18 months between 2012 and 2014 in Durham, working alongside Simon and enjoying and benefitting from every moment of it. I want to thank him for the good time in Durham.Also, I want to express my gratitude to NGI, and Knut H. Andersen and Suzanne Lacasse in particular, for giving me this opportunity by granting my application in 2011 to partially sponsor my PhD-plan.
