Numerical Simulation of CO2 sequestration into depleted natural gas reservoirs of Qatar

Considering that fossil fuels emit huge amount of carbon dioxide and contribute to climate change and global warming, countries have taken serious steps moving toward clean energies. Qatar, world’s largest supplier of natural gas, have committed to reduce its carbon emissions as part of its fulfillment of 2015 Paris agreement of climate neutral society. One of the ways that the country will most likely transition toward clean energy is through CO2 sequestration into gas reservoirs while producing blue hydrogen. Given its significance of reducing carbon emissions into the atmosphere, researchers performed several studies in relation to carbon capture and storage technologies, and impact on gas condensate reservoirs. However, little attention was given to the simulation modelling. Therefore, the objective of this research is to model CO2 sequestration into gas reservoirs in Qatar using QASR numerical simulation tool. Additionally, create a framework that integrates the impact of CO2 sequestration on the rock formation, environment, and economics.
