General description

Overview of Challenge

5

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

Natural movement of faults can alter the validity of geomechanical models and reservoir management plans.  These need to be well understood to ensure that reservoir management is appropriate to the changing reservoir.

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?

Production can decrease if fault line exposes alternative HC draw-down channels.  Reservoir management strategy may need to adapt to ensure injection resources aren't wasted

8

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

Seismics can see where faults are, but couldn't infer whether they had moved by a few mm's.

9

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

Ground movement satellite imagery could indicate where movement has occurred over known fault lines

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
