General description

Overview of Challenge

5

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

Outcrop mineralogy can be indicative of the mineralogy below the surface and therefore suggest how or how readily a formation may be produced.  This is most important for shale or tight reservoirs.

Outcrop analysis is relatively easily performed and it is generally cheap to do so, but it requires the deployment of ground staff to take samples.  This has a lag time associated with it and in hostile environments, this may also not be possible from a HSE perspective.

Thematic information requirements

11. Determine lithology, mineralogy and structural properties of the near surface,

7

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

If we could readily understand the lithology of formation outcrops without deploying ground staff, we could more rapidly and safely obtain an understanding of remote or hostile areas.  It would also enable us to make informed decisions earlier in the deci
