CDA DataStore
CDA DataStore Holding more than 6.5 million
curves of UKCS digital well log data, the
DataStore is one of the worlds largest
collections. The collection is available on-line
to CDA members and the DTI to share and use via a
secure entitlements and delivery system.

CDA DataStore Strategy Workshop

• Strengths
• Single point access to released and proprietary
  well data in common formats
• A simple, low-cost way of distributing and
  trading data
• A convenient way of submitting licence data to
  the DTI and release agents
• Once submitted to CDA well data is en route to
  the National Archive
• Weakness
• Incompleteness of the data sets

21
CDA DataStore Key Strategic Goals for 2004

• Completeness
• Maximise value for participants
• Service improvement
• Geographical extension
• Service development

22
CDA DataStore Goal 1 Completeness

• Causes of Incompleteness
• Its not easy to identify what is missing
• DTI does not enforce regulations
• Absence of focal points for submission within
  member companies
• Not all operators are CDA participants
• Incomplete scope (e.g. velocity data)
• Solutions
• DTI to persuade/mandate CDA use
• UKOOA encouragement to join CDA
• Work with Data Release Agents
• Adopt non-member wells
• DTI to submit non-member data
• Audit data submissions and advise operator
• Cataloguing improvements

• Priorities
• New wells
• Wells coming up to release
• Wells in archive features
• Released wells - high business value
• Remaining missing data

23
CDA DataStore Goal 2 Maximise Value

• Scope of the Value Study
• Articulate the benefits of participation
• Current value of CDA to individual members
• Gains from changing members business practices
• Increased value from changes to CDA
• Blockers and enablers
• Loss of net value if participation ceases
• Deliverables
• Synthesized analysis of current value
• Opportunities for increased value
• Blockers and cost of not participating
• Recommendations for changes in member behaviour
  and business practices
• Recommendations for changes in CDA

24
CDA DataStore Goal 3 Service Improvement

• Modify CS3 and apply to legacy data
• Modify CS8 and apply to legacy data Associate
  reports with their enclosures
• Implement generic company naming
• Identify and eliminate duplicate data
• Resolve orphaned data on PetroBank
• Correct legacy well name errors
• Team Workspace

Other Services
A range of valuable data management services is
provided to members by CDA. A close working
relationship with the DTI enables CDA to address
collective regulatory data matters for UKCS
licensees. CDA collaborates actively with other
national and international industry bodies to
broaden the base for co-operation on data and its
management.

Other Services PILOT Licence Data Initiative
Legal Framework the Challenge

• Legal Framework
• Licensees own the data.
• Licensees have joint and several rights and
  obligations.
• Licensees must preserve licence data and provide
  copies to the DTI on demand in perpetuity.
• The DTI has a right to collect data but must keep
  it confidential for the prescribed period.
• The DTI has a right to publish data (unless
  objection upheld), after the confidentiality
  period has expired.
• Well Cores and Samples must be kept at least 5
  years but may then be disposed of (after first
  being offered to the DTI).
• No legacy data obligations underlie new licenses.

• The Challenge
• Large volumes of complex data
• Wide variety of media and formats
• Cross-ownership and entitlement within and
  between licence groups
• Extensive duplication and redundancy
• Confusion over data ownership
• Confusion over data obligations and liabilities
• Very difficult to know what data exists
• Difficult for new entrants to get data
• Important data is degrading and is being lost
• Disposal regulations and costs are increasing
• 35 year legacy

• Archiving Well Data from the DataStore
• Well owner must first ensure that well is
  complete within the DataStore.
• BGS becomes the Well Owner (and therefore gets
  entitlement to the data) but pays no fees.
• DEAL Data Registry reflects this change.
• Requests for archived well data are satisfied by
  the NHDA
• BGS downloads data from the DataStore into the
  NHDA to satisfy the first request for an archived
  well.
• Subsequent requests from the public are met from
  the data stored in NHDA.
• CDA members continue to access data from the
  DataStore for as long as they see value.

CDA DataStore and the NHDA

• ADVANTAGES
• For CDA
• Best chance for completeness
• Minimised duplication with NHDA
• Online access remains available
• No real increased load on Landmark
• Value of DataStore enhanced
• For DTI
• Data preservation
• Data completeness
• For BGS/NHDA
• Lowest cost/lowest risk start
• For Data Release Agents
• Free access to complete BLD in CDA
• For Licensees
• Once-only data submission
• Low cost released data (BLD)
• For Value-adders
• Low cost released data (BLD)

• CHALLENGES
• Inclusiveness
• Way must be found for the DataStore to hold data
  for all wells/operators
• Completeness
• Data for all wells in the DataStore should be
  complete
• Point-forward data set
• Wells not yet released
• Released data set
• Competitive Conflict
• Release Agents and BGS/DTI need to agree when
  NHDA can make archived well data available
• DataStore data clean-up
• Must improve cataloguing and naming standards
• Must eliminate duplicates
• CDA Commercial Model
• Ensure any commercial consequences for members
  are equitably addressed
