KeyChallenges March 20117NDR10 | Country Report: UK

Key Challenges Data Quality & Completeness Missing dataMissing data –Weak regulatory enforcement –>40 years of data –Data does not follow asset sale –Poor curation practices: Media managementMedia management Cataloguing/labellingCataloguing/labelling Physical deteriorationPhysical deterioration –What does ‘complete’ mean anyway? Clean-up workClean-up work Well/wellbore modellingWell/wellbore modelling –PPDM’s “What is a well?” –Macondo response March 2011 NDR10 | Country Report: UKSlide 8 “Keep everything forever”

Regulatory ObligationsRegulatory Obligations –Licensees must retain data ‘in perpetuity’ –NHDA escape clause (archiving option) ChallengesChallenges –NHDA archiving is unaffordable for seismic –Regulations default to ‘retention in perpetuity’ –Significant legacy holdings on ‘old media’ –Su rvey redundancy not accepted CDA Seismic DataStoreCDA Seismic DataStore –Field data trial Key Challenges Seismic Field Data Oil & Gas UK | Exploration ForumSlide 9 March 2011 At least 500,000 9 track tapes are still held 9NDR10 | Country Report: UK
