General description

Overview of Challenge

5

What is the nature of the challenge? (What is not adequately addressed at present?)

Operations which use large quantities of water (EOR, SAGD, Fracking etc…) often draw water from water tables in the vicinity of reservoir.  In water-scarce regions, the ability to track aquifer behaviour can give valuable information to making the most of water resources and scheduling activity for the right times of the year.

6

Thematic information requirements

1. Obtain detailed topographic information,  3. Obtain detailed vegetation information,           13. Monitor ground movement,

7

Nature of the challenge - What effect does this challenge have on operations?

Good management can maximise benefits derived from water resources, reduce impact on the environment, local population and agriculture.  Cost benefits might also be realised by more efficient use and extraction of water.

8

What do you currently do to address this challenge?/ How is this challenge conventionally addressed?

If any, tilt meters, underground measurements of water table height

9

What kind of solution do you envisage could address this challenge?

 

10

What is your view on the capability of technology to meet this need? – are you currently using EO tech? If not, why not?
