CIDAI - OBJECTIVES

• To provide an improved service to users
• To reduce costs (CIDAI is an official CRINE
  project)
• Migration towards paperless operations
• To achieve common standards in data quality and
  accessibility

CIDAI Phase One Charge Structure -Operating
Costs...

• Fixed Operating Costs Are Covered By Annual
  Up-Front Equity Contributions Equal To...
• A Fixed Membership Fee - currently 10,000 / year
• A Fee Per Operated Well - currently 89 / year

16
CIDAI Phase One Charge Structure -Operating
Costs...

• Operating Profit Generated By...
• Fixed Fee Per Entitlement Change - Transaction
• Eg. Trading, Adding New Data Etc.
• Profit Redistributed Or Used For Future Phases
  According To Equity Share...

Company Equity Contribution Total Company
Fixed Contribution

• Equity Share

17
CIDAI Phase One Cost Savings - Transactions...

• Low Cost Entitlements Changes (Transactions)
  Will Replace Current Data Distribution Methods...
  
• Savings For Distribution of Data To Partners,
  Data Trading Public Release of Data
• There Will Be No Other Charges For Released Raw
  Data

18
CIDAI Phase One Financial Model - Cost-Benefit
Case...

• A Complex Balance of Several Factors...
• Equity Contributions
• Anticipated Numbers of Transactions Usage
• Forecasted Levels Of Activity and then charged
  following year on actual usage
• Data Deletion Timing Volumes
• Individual Implementation Scenarios
• Use As Complete Wireline Log Database
• Log Archive Only
• Run CIDAI In Parallel To Company Log Database

19
THE PROGRESS
Began with an idea!
Form a group and start a company!
Sign a contract
While designing, building and populating
the database.
20
Where do we start?????
Begin with the alphabet of CDA A Amerada Hess,
Amoco (digital wells) B BP (seismic) C Conoco
(hard copy) D DTI (standards) s Shell
(steering group) Together turning the vision
into reality!

Raw Well Log Data - Status
HIGHLIGHTS

• System went live in March 1996
• 70 of the legacy data loaded from B.Gas,
  Conoco, Shell, BPs databases
• Data can be downloaded in RP66, LIS and LAS
  formats
• Data selections can be downloaded eg. data over
  a depth range
• No longer have to send digital data to the DTI
• Raw well log data automatically available after
  5 1/2 years
• Standards have been agreed
• IRA Bomb tested our disaster recovery procedures
  for us!

BUT....

• Not all of the companies are connected yet -
  70 are!
• Most of the data is in the archive database and
  not immediately on-line
• We still have to check all our well data as part
  of the quality checking process
• Although we get raw well log data, its
  composited data most users want

25
Value - Added Well Log Data

• Erico and Robertsons both members of CDA
• CDA paid for their legacy value-added data to
  be loaded
• Robertsons have loaded all their composited
  legacy data
• Erico are in the process of loading the next
  release of data
• Companies are beginning to arrange for their
  value added data to be loaded
• CDA have defined a basic standard for well log
  joining which includes an audit trail

ISSUES

• Data is being prepared in LIS TIF format but if
  we can convert to Geoshare, it costs 50
  less to be loaded. (Load to Openworks and
  convert?)
• Do we have audit trails anywhere for wells we
  have composited in-house?

26
DEFINITION OF HARDCOPY

• All wireline, composite, mud and velocity logs
  that are on sepia, film or paper.
• Reports. (eg. geochemical, final well, core
  reports)
• Core samples will be addressed later.

27
Hard Copy Well Data - Status

• Conoco are driving the hard copy stage of
  CIDAI
• Took a year to agree on how to address well log
  hard copy data
• Business Case easy to define for CDA as a
  whole, but difficult for each company to
  assess individually (different working
  practices, preferences, contract prices and a
  lack of people who understand the whole arena
  of data management and in particular what it
  costs)
• Required DTI agreement and cooperation
• Paras hired as a consultant to assist in the EC
  tendering process
• Expect the proposed solution to begin
  implementation 4th Qtr 1997

SOLUTION

• One master dataset of hard copy data will be
  catalogued and stored (at the DTI, store in
  Edinburgh)
• Logs and Reports will be scanned to compile the
  second dataset
• Most recent wells will be scanned first
• Migrating to a paperless environment
