General description

Overview of Challenge

5

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

Identification of geological features can give reasonable and early indications of likely reservoir locations.  These are more easily seen in clear or deserted regions but areas of forested / agricultural land where the surface is covered or artificially modified, it is difficult to see these

6

Thematic information requirements

1. Obtain detailed topographic information,          11. Determine lithology, mineralogy and structural properties of the near surface,    14. Obtain detailed imagery of the surface,

7

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

If we are failing to identify geological indicators that suggest the presence of a reservoir then we have missed an opportunity.  If our competitors do this better than us the impact to our business could be huge.

8

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

Online imagery can be used in clear areas.  Geological maps can be used on a broader scale with inference to hills and larger structures.  There is no solution that gives us the accuracy we would like

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?

EO has applicability where the structure is exposed.  Forest/woodland / agricultural and most wetlands would mask the structure.
