▪ Abstract About two-thirds of primary energy today is used directly as transportation and
heating fuels. Any discussion of energy-related issues, such as air pollution, global climate …

Almost 20 years ago, the first CO2 capture and storage (CCS) project began injecting CO2
into a deep geological formation in an offshore aquifer. Relevant science has advanced in …

Underground accumulation of carbon dioxide (CO2) is a widespread geological
phenomenon, with natural trap** of CO2 in underground reservoirs. Information and …

The sequestration of CO2 in the deep geosphere is one potential method for reducing
anthropogenic emissions to the atmosphere without a drastic change in our energy …

The transition to renewable energy sources to mitigate climate change will require large-
scale energy storage to dampen the fluctuating availability of renewable sources and to …

The underground hydrogen storage (UHS) capacities of shut down oil and gas (O&G) fields
along the Norwegian continental shelf (NCS) are evaluated based on the publicly available …

At the Sleipner fields in the North Sea, CO2 is being injected into sands of the Miocene-
Pliocene Utsira Formation, which is overlain by thick Pliocene shales. The highly porous …

Permanent containment is paramount for geologic carbon sequestration. Petroleum
experience proves the possibility but also creates bias—to date, carbon storage projects …

The origin and permeability effects of carbonate cement, blamed for poor reservoir quality in
the Upper Triassic turbidite sandstones of the Lam Formation in Yemen, have been …
