Geophysics for modelling and monitoring the Earth's response to CO2 sequestration

碳捕获、使用和储存(CCUS)已被确定为英国要实现其净零承诺的关键一步。CCUS的商业部署将需要对注入的流体进行有效的测量、监测和验证(MMV)，这对地球物理，特别是地震技术提出了新的严峻挑战。该项目将把爱丁堡大学在二氧化碳储存和地震岩石物理方面的广泛记录与布里斯托尔大学在地质力学和微地震方面的专业知识以及BP作为CCUS主要行业领导者的地位结合在一起。一个关键目标是影响为即将到来的商业项目制定的监测战略。地震监测方法将使CCUS得到有效的商业采用，但它们本身不能为优化油藏管理提供足够的信息；与油藏建模和地质力学相结合是必要的。岩石物理理论的最新进展使得二氧化碳饱和岩石的地震响应可以与压力和流动参数联系起来。该项目将利用这些发展来创建监测二氧化碳注入的新的综合方法，并将它们应用于来自当前和计划中的CCUS操作的数据。

Carbon Capture Use and Storage (CCUS) has been identified as an essential step if the UK is to meet its net-zero commitments. Commercial deployment of CCUS will require effective Measurement, Monitoring and Verification (MMV) of injected fluids, posing new and serious challenges for geophysical, particularly seismic, technology.The project will bring together the University of Edinburgh's extensive track record in CO2 storage and seismic rock physics with University of Bristol's expertise in geomechanics and microseismic and BP's status a key industry leader in CCUS. A key goal is to influence the monitoring strategies being developed for upcoming commercial projects.Seismic monitoring methods will enable effective commercial adoption of CCUS, but by themselves they cannot provide enough information for optimal reservoir management; integration with reservoir modelling and geomechanics is necessary. Recent advances in rock physics theory allow the seismic response of CO2 saturated rock to be linked to pressure and flow parameters. The project will exploit these developments to create new integrated approaches to monitoring CO2 injection, and apply them to data from current and planned CCUS operations.
