Impact of Sedimentological Heterogeneity on CO2 Migration and Trapping Potential: HyNet North West project, Liverpool Bay, Offshore UK

地质碳储存被广泛认为是解决人为排放和气候变化的关键资产，以达到可持续的“净零”。地质非均质性在储层中起着重要的作用，因为它们控制着屏障和挡板的存在。它们的影响可以是积极的（例如，降低二氧化碳超过储存地点限制的速率），也可以是消极的（例如，减少导致二氧化碳损失的有效储存库体积）。因此，在评估CCS项目的风险和可行性时，了解二氧化碳储层的横向和垂直地质变化是一个关键方面。

Geological carbon storage is widely recognised to be a key asset in tackling anthropogenic emissions and climate change to reach a sustainable 'net zero'. Geological heterogeneities can play an important role in the storage units because they control the presence of barrier and baffles. Their impact can either be positive (e.g., decrease the rate at which the CO 2 exceeds the limits of the storage site), or negative (e.g., reduce the effective reservoir volume causing CO 2 loss). Accordingly, understanding the geological lateral and vertical variability of a CO 2 reservoir is a critical aspect when assessing the risk and viability of CCS projects.
