 Assessment of duricrusts and rock excavability

 

Challenge ID:

HCP-2503

Originator:

Onshore: Hatfield

Title:

Assessment of duricrusts and rock excavability.

Theme:

ON 2.5: Surface Geology Mapping - Engineering geological evaluation

Consortium Lead:

Arup

Interviewed Company:

Arup

Geography:

ON.REG.00 - Generic onshore

Challenge Description

What is not possible / not adequately addressed at present?

Need to improve identification of duricrusts and weathering profiles to assess rock excavability.

 

What effect does this challenge have on operations?

Reduces uncertainty, improves decision making for field development.

Early identification of constraints and opportunities.

Thematic information requirements:

Ortho base images

Lithology, structural geology,  surficial geology

Terrain information

Topographic information

What do you currently do to address this challenge? 

How is this challenge conventionally addressed?

Geotechnical Desk Study

Ground investigations and boreholes

Geological maps

Field geological mapping

Geophysics

Remote Sensing (multispectral) analysis

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

DEM analysis

High Resolution stereo DEM

Multispectral and hyperspectral

Automated classification processing

Geophysics

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

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

Best suited to use of high resolution optical imagery and high resolution DEM. Currently only rarely used because of perceived high cost. There is a need to educate industry to the cost-benefit value of using this data early on in project lifecycle - data
