CASE STUDY: RESERVOIR MONITORING WITH CORNER REFLECTORS (ALBERTA, CANADA)
 |
Objective of the project
With the introduction of the steam-assisted gravity drainage (SAGD) oil recovery technique, production efficiencies of 60 percent or better are now possible in heavy oil reserves. The objective of the project was to measure ground motion which should contribute to maximise steam injection efficiency with minimum risks for the extraction area.

Analysis and results
Installation of a network of more than 100 measurement points (Aluminium Corner Reflectors pairs).
Reflectors are adapted to site conditions: snow and cold temperature.
Ground motion monitoring with satellite images, without any intervention onsite.
New image every 1-3 days, updated results every 15 days.

The project monitors ground motion with a very high frequency: image update every
1-3 days and ground motion deliverables every 15 days.
1-3 days and ground motion deliverables every 15 days.
