Abstract
Abstract Sedimentary basins are suitable to a different degree for CO2 geological sequestration as a result of various intrinsic and extrinsic characteristics. This paper screened and ranked the Iullemmeden Basin of Nigeria sector based on Bachu 2003 ranking and screening criteria evaluating factors such as tectonic setting basin size and depth geology hydrogeology hydrocarbon potentials climate geothermal existing resources and industry maturity in respect to these criterion. The results shows to rank the Basin to have Rk score value of 0.41 against the fi n max fi value equal to 1 as highest value of the function characterize the best in terms of suitability for the criterion in which this ranking are based upon. The paper also reveals as findings of some intrinsic characteristics such as poor intercalated geologic formation shallow aquifer systems within sedimentary pile in the basin which make the basin not suitable CO2 sequestration and when other parameters in future are favoured it would possess the risk of CO2 leakages and groundwater contaminations in the geological storage media. Regional screening and ranking of the adjoining basins are recommended while detailed local site characterisation of the basin is needed to assess its overall suitability for CO2 sequestration potentials in Nigeria.
