Challenge ID:

HCP-1101

Originator:

Onshore: Hatfield

Title:

Identify areas with soft sediments to avoid strong attenuation.

Theme:

ON 1.1: Seismic Planning - Areas of poor coupling

Consortium Lead:

RPS Group

Interviewed Company:

RPS Group

Geography:

ON.REG.00 - Generic onshore

Challenge Description

What is not possible / not adequately addressed at present?

Poor attenuation may be experienced in areas of loose grained sand formations like dunes or the historic path of a river that’s changed course.

What effect does this challenge have on operations?

Poor data quality is experienced in areas where the source strength is easily dissipated.

Thematic information requirements:

Land cover

Terrain information

Topographic information

Water Quantity

Ortho base images

What do you currently do to address this challenge? 

How is this challenge conventionally addressed?

Current and historical topographic maps or satellite imagery to identify potential areas of change/hazard.

SRTM and Google Earth on global basis for early planning.

Conduct seismic work over winter on frozen ground (reduced attenuation).

Use prior knowledge.

Areas identified as potentially prone to poor seismic response are monitored during acquistion (reactive system).

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

A more scientific approach to correlate land classification against seismic quality.

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

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

Would consider improved data sources, e.g. elevation data resolution.
