Estimation of Thickness and Layering of Johansen and Cook Sandstones at the Potential Co2 Storage Site Aurora
(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)We have estimated the reservoir sand thickness and internal layering in the Aurora area, a planned geological CO2 storage site in the northern North Sea. The results are obtained by stochastic Markov chain Monte Carlo ... -
Fast Evaluation of Caprock Strength Sensitivity to Different CO2 Solutions Using Small Sample Techniques
(Peer reviewed; Journal article, 2021)The Draupne shale is a rock formation functioning as overburden for gas reservoirs in the Norwegian Sea and potentially as caprock for future CO2 storage locations as well. In this paper, the Draupne shale was exposed to ... -
From Pre-Screening to Monitoring of Plugged and Abandoned Marine Exploration Wells - Enabling Reuse of Reservoirs for Co2 Storage through Geophysical Monitoring
(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)Decommissioning of platforms and permanent plugging and abandonment (P&A) of oil and gas wells is a major future financial challenge for oil producing countries. This is especially true for offshore wells in deep water, ... -
How Fault Interpretation Method may Influence the Assessment of a Fault-Bound C02 Storage Site
(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)Interpretation of faults in the subsurface hinges on utilizing an optimum picking strategy, i.e. the seismic line spacing. Differences in line spacing lead to significant changes in subsequent fault analyses such as fault ... -
Inflow Performance of Cold Co2 Injection in Depleted Gas Fields
(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)Injection of CO2 in depleted hydrocarbon fields often leads to differences in temperature between the injected CO2 and the reservoir formation and fluids. A low pressure in the reservoir after depletion leads to decompression ... -
