Although dynamic modelling results have demonstrated good conformity with the field observations thus far, the long-term fate of CO2 remains uncertain. This is due to the lack of sufficient data regarding the geological characteristics of the far-field region in the reservoir. In this paper, the authors describe a methodology to quantify these uncertainties in order to perform a site-specific risk assessment for the postclosure period. © 2014 The Authors.

The optimal design should also take into account the uncertainties associated with the subsurface (e.g., petrophysical attribution and structural relationships). Detailed geological models along with different realisations for handling uncertainties increase the computational overheads, making the optimisation problem intractable. To circumvent this problem, upscaled models can be used to speed up the identification of optimal solutions. Nevertheless, a grid resolution, which does not compromise the accuracy of the optimisation in an upscaled model, must be carefully determined. The methodology described in this paper aims to address this requirement. In this study, a 3D geological model, comprising the main oil reservoirs of the Forties and Nelson hydrocarbon fields and the adjacent saline aquifer, was built to examine the use of coarse grid resolutions to design an optimal CO2 storage solution for this area within the UK Central North Sea. Simulation results for single objective optimisation show that an upscaled grid resolution can be identified which is a trade-off between accuracy and computational time. The outlined methodology is generic in nature and can be ported to other similar optimisation problems for CO2 storage.

The methodology is applied to the In Salah case study dataset in order to validate the developed technique. The EnKF approach is used to estimate the parameters controlling the performance of the CO2 storage site by assimilating data from multiple sources. The controlling parameters in this study are fault/fracture transmissibility and anisotropic permeability at the injection wells; and the data sources are the injection wells' flowing bottom-hole pressure (FBHP) and Interferometric Synthetic Aperture Radar (InSAR) surface deformation. The methodology is shown to be effective in updating the parameters controlling the performance of the CO2 storage site.

We examined the association between ghrelin and gastroesophageal cancers and atrophic gastritis in a population-based setting.
