General description

Overview of Challenge

5

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

It is often challenging to track injected fluids such as those used for EOR/ IOR.  Data that can give information to identify where fluid migration has gone to can be very valuable.

6

Thematic information requirements

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

7

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

Costs related to the loss of injection fluids in the reservoir can be large.

8

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

subsurface sensors, including acoustic, electrical and gravity sensors can be used

9

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

Ground movement satellite imagery could indicate sub-surface pressure build up due to injected fluid migration from observed surface movement

10

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

EO could be a useful complimentary technology
