Storage Sites for Carbon Dioxide in the North Sea and Their Particular Characteristics

“…In the existing numerical simulation studies of carbon dioxide sequestration in the North Sea, much work has focused on measuring the reservoir storage capacity, and less work has been conducted on studying the caprock and interlayer integrity during carbon dioxide sequestration within detailed numerical models [10,[52][53][54][55][56][57][58]. More simplified models do not combine all the different processes that occur during and after carbon dioxide injection.…”

On obtaining optimal well rates and placement for CO2 storage

“…As discussed in a recent review by Bachu [2], local storage potential should be estimated using site-specific calculations to be able to account for all the factors important for storage. In addition to this, there are several site-specific simulation studies [48,16,19,17,49], benchmark comparisons [13,42], or demonstration of new methods for CO 2 -specific simulation methods [20,32,11]. Presently, more and more surveys are aimed at providing detailed storage capacity estimates for largescale regions containing plausible storage sites [29,8,15,23,35,47,14].…”

Ranking and categorizing large-scale saline aquifer formations based on optimized CO 2 storage potentials and economic factors

“…Indeed, efforts have been made to develop methods of evaluating a particular set of saline aquifers and/or oil reservoirs, e.g., in the USA [2], Canada [3], Australia [4], South Africa [5], Ireland [6], the UK [7,8], the Netherlands [9], and Nordic regions [10,11,12,13,14]. These evaluation methods make use of quantitative criteria such as storage potentials, reservoir and sealing properties, proximity to CO 2 point sources, and storage costs, while others include qualitative measures such as leakage risk, safety, and data coverage.…”
