General description

Overview of Challenge

5

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

Infrastructure that has moved vertically or horizontally relative to the subsurface can lead to damage causing events.  For example a well-head that moves relative to the subsurface could lead to dangerous damage or ultimate failure of the production string or the completion.

6

Thematic information requirements

1. Obtain detailed topographic information,        9. Obtain detailed imagery of assets,     13. Monitor ground movement,

7

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

Lost production, avoidable interventions, environmental damage

8

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

Physical markers at the site are used to track subsidence.  However, these only track movement in specific areas, and if the wider site has moved then this will not be picked up.  Furthermore, the site needs to be visited to see this activity - it can't b

9

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

Ongoing data to highlight ground movement which could lead to failure events

10

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

Relative infrastructure movement on the surface can give inferred warning signals to catastrophic potential failure sub-surface.
