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.

如果英国要实现其净零排放承诺，碳捕获、利用和封存（CCUS）已被确定为必不可少的一步。CCUS的商业部署将需要对注入流体进行有效的测量、监测和验证（MMV），这对地球物理技术，特别是地震技术提出了新的严峻挑战。该项目将结合爱丁堡大学在二氧化碳封存和地震岩石物理方面的广泛记录，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在CCUS领域的关键行业领导者地位。一个关键目标是影响正在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能够有效地商业化应用，但它们本身不能为最佳油藏管理提供足够的信息；油藏建模和地质力学的结合是必要的。岩石物理理论的最新进展使CO2饱和岩石的地震响应与压力和流量参数联系起来。该项目将利用这些发展创造新的综合方法来监测二氧化碳注入，并将其应用于当前和计划中的CCUS操作数据。
