Satellite InSAR Data: Reservoir Monitoring from Space
|Instructor||Alessandro Ferretti (Tele-Rilevamento Europa - Milan, Italy)|
|Disciplines||Airborne Exploration, Reservoir & Production Engineering|
|Book||Available in EAGE Bookshop|
The course will conclude with a brief discussion of the new satellite sensors to be launched in the next few years and the new trends in data integration and visualization.
Upon completion of the course, participants will be able to:
- Understand the key interest of InSAR for geoscientists and engineers;
- Understand the basic concepts behind Synthetic Aperture Radar (SAR) sensors;
- Appreciate the main differences between SAR and optical images;
- Understand the basic data requirements, assumptions, limitations and applicability of SAR interferometry (InSAR);
- Discover advantages and limitations of advanced InSAR techniques for estimating sub-centimetre surface deformation phenomena from space;
- Realize why InSAR data are becoming a standard tool for surface deformation monitoring;
- Compare InSAR data with in situ measurements, such as: GPS and tiltmeters;
- Understand how surface deformation can be related to geophysical parameters at depth;
- See how InSAR data are an effective tool for monitoring subsidence phenomena;
- Understand the importance of surface deformation monitoring in Cabon Capture and Sequestration (CCS) and Underground Gas Storage (UGS) projects;
Understand why InSAR data can be used as a cost-effective tool for reservoir management, as well as a risk mitigation tools
Start thinking about future applications of satellite radar data, possibly in synergy with other in-situ observations.
1) Introduction: why are satellite radar data relevant?
2) Synthetic Aperture Radar (SAR) sensors: acquisition geometry and image formation
3) Measuring range variations: the magic of SAR interferometry (InSAR)
4) A tool for elevation model reconstruction and surface deformation analysis
5) Advanced InSAR techniques: from qualitative to quantitative data
6) From surface deformation to volume and pressure changes at depth
7) Overview of possible applications: subsidence monitoring, fault characterization, calibration of geological models, reservoir monitoring
8) Time-lapse data for Carbon Capture and Sequestration (CCS), Underground Gas Storage (UGS), secondary and tertiary (EOR) oil recovery projects
9) Available data sources and historical archives of SAR data. A quick overview of other InSAR applications
10) Summary and future trends
The course is designed for anyone who would like to understand how satellite sensors can measure surface displacements to a fraction of a centimetre from space. It is not a course for radar specialists. Reservoir engineers, geophysicists, geodesists, geologists should all be interested in this new tool for surface deformation monitoring that is becoming more and more a standard. Radar data are still largely unknown, but their impact on oil&gas and civil protection applications can be huge.
Rather than a strong background in remote sensing, geophysics and calculus, curiosity is probably the most important prerequisite. The course can be understood by geoscientists and engineers with a moderate mathematical background.
About the instructor
In 2000 he founded the company “Tele-Rilevamento Europa” (TRE), offering high-quality surface deformation data for many different applications, from oil/gas reservoir surveillance, to landslide monitoring. Since 2008, he has been acting as Chairman of the Board of TRE Canada Inc. In June 2012, Alessandro Ferretti, together with Prof. Fabio Rocca, was awarded the “ENI Award 2012” for the potential impact of the PSInSAR™ technology on the oil&gas sector. TRE is now TRE ALTAMIRA, after the integration with Altamira Information in 2016. Alessandro Ferretti is currently CEO of the TRE ALTAMIRA group, having offices in Milan, Barcelona and Vancouver (BC). He coauthored more than 100 technical publications in international journals.
