4D 地震有效用于地下二氧化碳羽流监测

本文的作者展示了贫化碳酸盐岩储层内 CO2 羽流的迁移，以及注入期间 CO2 饱和度和压力增大对时移 4D 地震波一致性监测的预期影响。

枯竭碳酸盐岩储层中的二氧化碳 (CO 2 ) 封存需要采用全面且创新的监测技术。4D 时移地震对于监测、测量和验证 (MMV) 规划是必要的，以演示 CO 2羽流在地质储存中的迁移。用于监测 CO 2羽流的自适应、针对具体地点的 MMV 计划对于最大限度地减少可能的地下和项目完整性风险至关重要。在整篇论文中，作者探讨了贫化碳酸盐岩储层内 CO 2羽流的运移，以及注入过程中 CO 2饱和度和压力增大对时移 4D 地震波一致性监测的预期影响。

4D Seismic Used Effectively in Subsurface CO2 Plume Monitoring

The authors of this paper show the migration of a CO2 plume within a depleted carbonate reservoir and the expected effects of CO2 saturation and pressure buildups during injection on time lapse 4D seismic for conformance monitoring.

Carbon dioxide (CO2) sequestration in depleted carbonate reservoirs requires the incorporation of comprehensive and innovative monitoring technologies. 4D time-lapse seismic is necessary for monitoring, measurement, and verification (MMV) planning to demonstrate the migration of CO2 plumes within geological storage. An adaptive, site-specific MMV plan for monitoring CO2 plumes is critical to minimize possible subsurface and project-integrity risks. In the complete paper, the authors explore the migration of CO2 plumes within depleted carbonate reservoirs and the expected effects of CO2 saturation and pressure buildups during injection on time-lapse 4D seismic for conformance monitoring.

Integrated Reservoir Dynamic Simulation

In the current study, a depleted carbonate reservoir gas field was identified for near-future CO2 sequestration offshore Sarawak.
