General description

Overview of Challenge

5

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

Safety and environmental impact of fracking can be monitored via looking at surface uplift and subsequent relaxation.  It would be expected to see a some elastic and some permanent deformation, once the subsurface has been fracked.  There is a need for technology to provide verification of no movement or quantify the amount of movement and indicate whether this movement was caused by the fracking itself.

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?

Due diligence: early diagnosis of communication between fracking zone and other zones - thus limitation of environmental impacts.

8

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

surface and downhole monitors can track if hydrocarbons are communicating between layers.  Downhole gravity sensors are a technology which is likely to address this need to some degree in the future.  However, these technologies have their limits.

9

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

Ground movement satellite imagery could indicate surface movement and infer fluid migration of fracking fluids

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
