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

人们普遍认为，地质碳储存是应对人为排放和气候变化以实现可持续的“净零”的关键资产。地质非均质性可以在存储单元中发挥重要作用，因为它们控制着障碍物和障碍物的存在。它们的影响可以是积极的(例如，减少二氧化碳超过储存点限制的速度)，也可以是负面的(例如，减少导致二氧化碳损失的有效储油量)。因此，在评估CCS项目的风险和可行性时，了解CO2储集层的地质横向和纵向变异性是一个关键方面。

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.
