Challenge Description

What is not possible / not adequately addressed at present?

In enhanced oil recovery operations, there is a need to understand the behaviour of the reservoir when there are injection wells and extraction wells.  Long term monitoring is required over large areas and integrated with processes such as injection / extraction cycles.

What effect does this challenge have on operations?

Costs of operations.

Thematic information requirements:

Surface motion (horizontal and vertical)

Distribution and status of infrastructure

Topographic information

What do you currently do to address this challenge? 

How is this challenge conventionally addressed?

Limited InSAR. Reservoir models. Drill/well logs. Tilt meters, which are expensive.

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

InSAR, but timeliness is an issue – how quickly can get the product from an operational perspective to support sub-surface operations.  Long term monitoring is required over large areas. Focused monitoring for short term processes such as injection. Looki

What is your view on the capability of technology to meet this need?

Are you currently using EO tech? If not, why not?

InSAR can be a challenge at X- and C-band and L-band would help to address issues. Quality of correlation and product accuracy. Quantitative assessment of coherence of a product.
