Abstract

Summary

This paper describes key aspects of the methodology for technical subsurface evaluation of the South Morecambe offshore gas field to investigate its potential as a future high-capacity CO2 storage site.

The integrated dynamic modelling approach involves a progressive evolution from phenomenological models to full field predictive models, using advanced reservoir simulation workflows. The phenomenological models help to understand physical and chemical behaviour in the subsurface storage system. For the full field models, high-resolution gridding captures fine-scale features and heterogeneity, to achieve a more accurate representation of the reservoir. Compositional modelling provides a detailed description of fluid phase behavior, together with specialist options such as CO2 dissolution in the aqueous phase. This paves the ground for further studies of geomechanical and thermal effects. The suite of models, at different levels of detail, supports analysis of near-wellbore behavior during injection and provides insights into plume movement and trapping mechanisms over the life of the storage system.
