减少二氧化碳排放对缓解气候变化至关重要。碳捕集与封存(CCS)是实现净负排放的少数技术之一。然而,由于二氧化碳渗流动态和储层属性存在不确定性,预测 CCS 中的流体流动模式仍具挑战。在现有地震成像方法如联合恢复法(JRM)缺乏不确定性量化的基础上,本文提出概率联合恢复法(pJRM)。通过使用共享生成模型对多期调查中的后验分布进行估计,pJRM 提供了不确定性信息,从而提升 CCS 项目的风险评估能力。

原文摘要 · Abstract (English)

Reducing CO$_2$ emissions is crucial to mitigating climate change. Carbon Capture and Storage (CCS) is one of the few technologies capable of achieving net-negative CO$_2$ emissions. However, predicting fluid flow patterns in CCS remains challenging due to uncertainties in CO$_2$ plume dynamics and reservoir properties. Building on existing seismic imaging methods like the Joint Recovery Method (JRM), which lacks uncertainty quantification, we propose the Probabilistic Joint Recovery Method (pJRM). By estimating posterior distributions across surveys using a shared generative model, pJRM provides uncertainty information to improve risk assessment in CCS projects.
