Geological Storage of CO2 in Deep Saline Formations by Auli Niemi, Jacob Bear, Jacob Bensabat

By Auli Niemi, Jacob Bear, Jacob Bensabat

This e-book deals readers a entire evaluate, and an in-depth realizing, of compatible tools for quantifying and characterizing saline aquifers for the geological garage of CO2. It starts off with a common evaluation of the method and the approaches that happen while CO2 is injected and saved in deep saline-water-containing formations. It accordingly provides mathematical and numerical types used for predicting the implications of CO2 injection.
This ebook offers descriptions of suitable experimental equipment, from laboratory experiments to box scale web site characterization and methods for tracking spreading of the injected CO2 in the formation. reports from a couple of vital box injection tasks are reviewed, as are these from CO2 common analog websites. finally, the publication provides suitable threat administration methods.
Geological garage of CO2 is extensively thought of to be a key expertise able to considerably lowering the quantity of CO2 published into the ambience, thereby lowering the damaging affects of such releases at the international weather. all over the world, tasks are already in complete swing, whereas others at the moment are being initiated and carried out to illustrate the expertise.
Deep saline formations are the geological formations thought of to carry the top garage capability, because of their abundance around the globe. so far, besides the fact that, those formations were particularly poorly characterised, as a result of their low fiscal worth. hence, the methods considering injecting and storing CO2 in such formations nonetheless have to be larger quantified and strategies for characterizing, modeling and tracking this kind of CO2 garage in such formations needs to be speedily built and refined.

Niemi et al. -F. Tsang and A. Niemi The next section below gives an overview of the processes involved in a basic scenario of subsurface CO2 injection and sequestration in a brine formation, followed by a general discussion of the geological settings and characteristics. Then the approach for discussing the relevancy of the physicochemical processes to CO2 geosequestration at a specific site is presented. The implementation of this approach with an example of application to two field cases is described and discussed in the remaining sections of this chapter.

This will give rise to uncertainty because of lack of knowledge. Some research effort has been devoted to the definition and estimation of uncertainty: it is hoped that the uncertainty can be bounded, based on site-specific data on a large scale. 8 Processes Processes involved in CO2 geosequestration are discussed in detail in Chaps. 3–5 of this book. Below, they are presented in an outline way under processes, process representations, and coupled processes. 1 Processes Under processes, we identify below some significant hydrological, chemical, mechanical, and thermal processes relevant to CO2 geosequestration: • Flow of supercritical CO2, gaseous CO2, brine with dissolved CO2, and in situ brine, including “impurities” injected with the CO2.
