General description

Overview of Challenge

5

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

Where a well is producing from multiple zones (e.g. in long horizontal wells which target different producing zones), the ultimate draw-down can be hampered if the zones produce at non-expectant rates.

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?

Maximum production from a reservoir might not be achieved

8

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

Downhole tools, in hand with Intelligent completions / passive inflow control devices.

9

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

Ground movement imagery could confirm drawdown in certain zones

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 complimentary technology, but only where producing zones are not vertically on top of each other (e.g. with long horizontals etc..)
