This is one of the early papers on CO2 storage. Natural analogues indicate that it is possible to dispose of CO2 underground in closed structures on deep aquifers. Disposal into depleted or exhausted hydrocarbon fields has many advantages, e.g. proven seal, known storage capacity, no exploration costs. Unfortunately there are very few hydrocarbon fields in the UK onshore area, and their total CO2 storage capacity is very low compared to annual UK CO2 production from power generation. The best aquifers for CO2 disposal onshore are the widespread Permo-Triassic sandstones. Further onshore potential exists in younger Mesozoic reservoirs. Offshore, disposal into depleted oil fields (where cost credits from enhanced oil recovery could be beneficial) or the Perno-Triassic gas fields of the southern North Sea, and nearby associated closures of the Triassic Sherwood Sandstone aquifer, appear to provide the best prospects. doi:10.1016/0196-8904(93)90038-C. http://www.sciencedirect.com/science/article/pii/019689049390038C
