Natural Geochemical Analogues for Carbon Dioxide Storage in Deep Geological Porous Reservoirs, a United Kingdom Perspective — Elevated concentrations of atmospheric CO2 are implicated in global warming. Mitigation of this requires capture of CO2 from fossil fuel power sources and storage in subsurface aquifers or depleted hydrocarbon fields. Demonstration(More)
The principles of hydrocarbon exploration and production provide well established and tested principles and technologies to investigate storage of fluids in the subsurface. CO2 can be stored in the subsurface using settings of: A) thick permeable coal seams; B) depleted oil and gas fields; C) saline aquifers of regional extent, with an overlying seal. The(More)
Governments worldwide should provide incentives for initial large-scale GS projects to help build the knowledge base for a mature, internationally harmonized GS regulatory framework. Health, safety, and environmental risks of these early projects can be managed through modifications of existing regulations in the EU, Australia, Canada, and the U.S. An(More)
The effective geological storage of liquid CO2 in porous subsurface rock will require the ability to track, and identify the origin of, any CO2 seepage measured at the near-surface. In a study relevant to postemplacement seepage, we examine natural CO2 springs around Green River, on the Colorado Plateau USA, in an attempt to determine the CO2 origins. We(More)
Industrialized societies which continue to use fossil fuel energy sources are considering adoption of Carbon Capture and Storage (CCS) technology to meet carbon emission reduction targets. Deep geological storage of CO(2) onshore faces opposition regarding potential health effects of CO(2) leakage from storage sites. There is no experience of commercial(More)
Inherent tracers-the "natural" isotopic and trace gas composition of captured CO2 streams-are potentially powerful tracers for use in CCS technology. This review outlines for the first time the expected carbon isotope and noble gas compositions of captured CO2 streams from a range of feedstocks, CO2-generating processes, and carbon capture techniques. The(More)
Carbon dioxide enhanced oil recovery (CO2EOR) is a proven and available technology used to produce incremental oil from depleted fields while permanently storing large tonnages of injected CO2. Although this technology has been used successfully onshore in North America and Europe, there are currently no CO2EOR projects in the United Kingdom. Here, we(More)
Structural and residual trapping of carbon dioxide (CO2) are two key mechanisms of secure CO2 storage, an essential component of Carbon Capture and Storage technology. Estimating the amount of CO2 that is trapped by these two mechanisms is a vital requirement for accurately assessing the secure CO2 storage capacity of a formation, but remains a key(More)
