| Abstract | Ground deformation in the Cold Lake, Alberta, region was measured with Differential Interferometric Synthetic Aperture Radar (DInSAR) from RADARSAT-2 imagery acquired during 2008-2013. Deformation maps
presented here show subsidence and uplift produced during oil extraction. Typical values of ground deformation were in the range of and sometimes exceeding 10-30 cm over the 24 day satellite repeat period, which is more than 10 times faster than in
other oil sands region that CCMEO has studied in collaboration with the Alberta Energy Regulator (AER). Significant deformation, both uplift and subsidence, was observed in regions where oil leaks were reported. These regions are shown as brown
rectangles. This analysis may be significantly improved if ground based data such as, steam pressure, injection steam and oil extraction rates were used. |
| Summary | (Plain Language Summary, not published)
In this study, satellite Interferometric Synthetic Aperture Radar (InSAR) measurements were used to assess ground deformation over an active oil-sands
site in near Cold Lake Alberta. RADARSAT-2 data acquired every 24 days during 2008-2013 was used. Deformation maps presented in this report show subsidence and uplift produced during steam-assisted oil extraction. Typical values of ground deformation
were in the range of 10-30 cm over the 24 day satellite repeat period, sometimes greater. This represents more than 1 cm per day, which is over 10 times faster deformation rates observed in other oil sands regions currently being studied in
collaboration with the Alberta Energy Regulator (AER). Significant deformation, both uplift and subsidence, was observed in regions (shown as brown rectangles) where recent oil leaks were reported. |
