Distributed Acoustic Sensing (DAS) Seismic Monitoring of CO2 Injected for Enhanced Oil Recovery in Northern Michigan

As part of the Midwest Regional Carbon Sequestration Partnership (MRCSP) Phase III project, a monitoring study was conducted to assess the effectiveness of DAS (Distributed Acoustic Sensing) -based VSP (Vertical Seismic Profiling) technology for delineating CO2 injected into the Silurian-age pinnacle reefs in northern Michigan, the host rocks for the MRCSP Phase III demonstration project. The DAS VSP study was conducted in the Chester 16 reef, one of several reefs in Otsego County Michigan that is operated by Core Energy, LLC of Traverse City, Michigan.

作为中西部区域碳封存伙伴关系（Midwest Regional Carbon Sequestration Partnership, MRCSP）第三阶段项目的组成部分，本研究开展了一项监测研究，以评估基于分布式声波传感（Distributed Acoustic Sensing, DAS）的垂直地震剖面法（Vertical Seismic Profiling, VSP）技术的有效性，该技术用于刻画注入至密歇根北部志留纪尖礁内的二氧化碳（CO₂）分布——上述志留纪尖礁正是MRCSP第三阶段示范项目的储集岩层。本次DAS-VSP监测研究实施于切斯特16号礁，该礁是密歇根州奥特塞戈县境内由密歇根州特拉弗斯城的核心能源有限责任公司（Core Energy, LLC）运营的多个礁体之一。
