General description

Overview of Challenge

5

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

Old well records are commonly inaccurate because the final well location has not been recorded correctly.  In some instances, the record does not even exist because it has been lost or destroyed.

It would be beneficial to have a way of remotely validating the location of the well e.g. through the identification of disturbed ground, the presence of historical roads or other infrastructure

Thematic information requirements

9. Obtain detailed imagery of assets,    12. Identify the presence of sub-surface or covered infrastructure,   14. Obtain detailed imagery of the surface,

7

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

Risk of being seen as negligent.  Also cost implications if existing infrastructure is not used.  Biggest implication is that wells cannot be brought back on line, and profit subsequently not realised.

8

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

Company records, together with mapping, but both may be inaccurate / not fully inclusive.
