“…And of the second (p.14): "For well-selected, designed and managed geological storage sites, the vast majority of the CO 2 will gradually be immobilised by various trapping mechanisms and, in that case, could be retained for up to millions of years." [An excellent early overview of the whole set of issues involving CCS, including risks, can be found in Benson (2007Benson ( , 2008].…”

Long lists of issues relevant to carbon capture and storage projects have been provided in a number of sources, encompassing the broad categories of technological risks, health and environmental risks and societal risks. From these long lists a selection of ten major issues, broken down into three broad categories, has been made. The selected issues are: 1) government and industry factors (competent regulatory oversight; adequate risk assessment and risk management frameworks; and supportive public policy architecture); 2) environmental risk factors (adequate site-specific characterisations of geological formations for CCS storage sites worldwide; credible monitoring of storage site performance; and the possibility of leaking from storage); 3) socioeconomic factors (tolerable economic costs; public perceptions of risks and benefits; information provision, effective communication and stakeholder engagement; and social and public acceptability, including the use of decision support mechanisms). The paper emphasises that what is unique about carbon capture and storage, considered as a major set of risk issues of global proportions, is how proactively these relevant major risks and risk factors have been identified and characterised by major institutional actors, especially industry and governments.

“…Here, the role of the instrument is to assist in the identification of subterranean rock structures through their particular gravity gradient signatures [12,13]-which may, for example, indicate the presence of useful mineral deposits, oil, or gas. On the other hand, there is currently much interest in the sequestration of captured CO 2 in depleted oil or gas wells [14], where the continued presence of a subterranean plume of pressurized CO 2 , in liquid form, might be monitored remotely via its gravity gradient signal. Moreover, there are other conceivable uses for gravity gradiometers beyond those just mentioned, some of which would exploit a gravity gradiometer's potential for working equally well with more compact gravitational anomalies than those discussed above.…”

This paper discusses the use of signals from tensor gravity gradiometers to target compact, local, subterranean voids. Two generic types of gravitational source are analysed in detail, and compared: a cubical subterranean void, and a subterranean tunnel. A vectorial targeting method is shown to work well with both types of finite target, picking out the centre of mass of the cubical source, and the axis of the tunnel. Some unusual results are reported in connection with the apparent length of the tunnel target, and limitations on the information that may be gleaned from the gravity gradient signals arising from both types of target are discussed.
