加拿大萨斯喀彻温省东南部的韦伯恩油田（图1）于1954年被发现，自20世纪60年代以来一直被水淹没。2000年10月，EnCana开始注入二氧化碳以提高石油采收率，同时开展了一个多学科的国际能源机构温室气体二氧化碳监测和储存项目。为了监测二氧化碳注入、储存和石油开采，从1999年12月的基线调查开始，采集了多个年份的3D和3D/3-C数据。这些延时数据集用于评估CO2封存的质量和安全性，并监测储层压力前沿、水驱和旁通油（白色等人，2004年）。
The Weyburn Field in southeastern Saskatchewan, Canada (Figure 1) was discovered in 1954 and has been water-flooded since the 1960s. In October 2000, injection of CO2 for enhanced oil recovery was started by EnCana, concurrently with a multidisciplinary International Energy Agency Greenhouse Gas (IEA GHG) CO2 Monitoring and Storage Project (CO2MSP). In order to monitor CO2 injection, storage, and oil recovery, several vintages of 3D and 3D/3-C data were acquired, starting with a baseline survey in December 1999. These time-lapse data sets were used to evaluate the quality and safety of CO2 sequestration, and monitor the reservoir pressure front, water flooding, and bypassed oil (White et al., 2004).
