Assessment of Sites for CO2 Storage and CO2 Capture, Utilization, and Storage Systems in Geothermal Reservoirs

CO2 EOR and Storage in Oil Reservoirs

CO2 EOR and Storage in Oil Reservoirs — CO2 injection into tertiary oil reservoirs has been widely accepted as an effective technique for enhanced oil recovery (EOR), and has been used by the oil industry for over 40 years. Concerns over greenhouse gas emissions are leading to the investigation and realisation of its potential as a carbon storage method in recent years. With the right reservoir...

Comparison of Co2 Abatement by Use of Renewable Energy and Co2 Capture and Storage

Emissions of CO2 and other greenhouse gases to the atmosphere will need to be greatly reduced to avoid the risk of harmful climate change. There are many different ways of reducing emissions of greenhouse gases. It is important to be able to understand how the different options compare. This paper includes a comparison of the costs of three different options for reducing emissions of CO2; wind ...

Geologic Storage of CO2

Dynamic imaging provides an effective way to integrate previous time-lapse data with current data in order to estimate a current model. We present two methods useful for continuous dynamic reservoir and subsurface monitoring. The first method is a stochastic method for the inversion of geophysical data. It uses the ensemble Kalman filter (EnKF) that we demonstrate using time-lapse surface seism...

Geologic Storage of CO2

CO2-storage assessment and effective capacity in Algeria

Deep saline aquifers widely distributed deep in the earth offer the greatest CO2 storage potential in all current geological CO2 storage approaches. The western region of the Saharan platform in Algeria includes several sedimentary basins characterized by a large production of dry gas with high CO2 rates sometimes exceeding 9 %. To reduce CO2 emissions, these basins were analyzed to identify th...
