Key Challenges

March 2011 7NDR10 | Country Report: UK

Key Challenges

Data Quality & Completeness

• Missing data– Weak regulatory enforcement– >40 years of data– Data does not follow asset sale– Poor curation practices:

• Media management• Cataloguing/labelling• Physical deterioration

– What does ‘complete’ mean anyway?• Clean-up work• Well/wellbore modelling

– PPDM’s “What is a well?”– Macondo response

March 2011 NDR10 | Country Report: UK Slide 8

“Keep everything forever”

• Regulatory Obligations– Licensees must retain data ‘in perpetuity’– NHDA escape clause (archiving option)

• Challenges– NHDA archiving is unaffordable for seismic– Regulations default to ‘retention in perpetuity’– Significant legacy holdings on ‘old media’– Survey redundancy not accepted

• CDA Seismic DataStore – Field data trial

Key Challenges

Initiatives

DM Value Study

• Findings:1. 73% of the value of E&P activity comes from

an understanding of the subsurface2. 38% of this understanding comes from data3. Therefore combining 1 and 2:

28% of E&P value comes from Data

• Initiative led by CDA in the UK– Oil companies– Service companies and consultants– Academia– International scope

• Competency Map (by the end of June 2011)

• Accreditation Scheme (by the end of 2011)

Initiatives

Professionalising DM
