General description

Overview of Challenge

5

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

Areas of soft ground can absorb the seismic signal and consequently distort the output data.  These areas need to be identified and considered when planning seismic lines, to ensure data quality is maintained.

6

Thematic information requirements

2. Obtain detailed terrain characterisation,  4. Obtain detailed land-use information,        11. Determine lithology, mineralogy and structural properties of the near surface,

7

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

Quality of output can be reduced if the sources coincides with soft surface conditions. This can ultimately lead to reservoir understanding being hampered, and thus a reduction in potential production.

8

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

Data algorithms can be used to correct data

9

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?
