NPD Fact pages - Well data

• Core photos from selected wells have now been
  published on the NPD's fact pages. The photos of
  core samples taken during drilling provide
  important information on the seabed rocks.
• WDSS (Well Data Summary Sheets) for selected
  released wells have now been published on the
  NPD's fact pages.
  
• These contain a summary of data
• As well as general information and technical
  data, WDSS also contain well history, well
  testing results, geological interpretations of
  formation tops and geochemistry for the well. In
  addition, WDSS provide an overview of at what
  depths and intervals the NPD has cuttings and
  drilling cores from a given well.

DISKOS basics

• Mandatory to submit all new data to DISKOS
• (government reporting requirements)
• Database contains both confidential and public
  data
  
• What is public varies with time
• Membership required to download data online
• Non-members can get physical copies of public
  data
  
• Members can buy additional services

20
History - The Diskos Project

• The Diskos Project requirements specifications
  and application to tender were sent out in June
  1993
  
• To establish a joint database for quality
  controlled geodata and to make this data
  available to users
  
• An open solution able to interact with other
  solutions
  
• Main focus on digital seismic data
• POSC Data model (Epicentre)
• UNIX-based client-server environment
• GIS Gui (e.g. ArcInfo)
• Water-tight security and use World Class
  technology were specific demands.
  
• The system must control ownership, entitlements
  (access rights) and trade transactions to each
  survey, line, line segment for original and
  reprocessed data

21
Issues......

• Technical
• Number of involved companies
• Work processes ( incl quality requirements)
• Budget requirements
• Software development
• Projects ( incl loading of historic data )
• Cost split between members

22
Diskos Organisation

• The key to success has been a climate of
  collaboration and mutual understanding
  
• Different members
• The authorities
• Major Oil Companies
• Smaller Oil Companies
• New Companies on the NCS
• Diskos Work Groups has been a key to establishing
  good solutions
  
• Challenge is to maintain a firm industry focus
• Perception that Diskos now works and does not
  need the same level of commitment as before. This
  must be avoided!

DATATYPES

• Administrative data
• License, block, quadrant, coastlines, national
  borders
  
• Field, platform, pipeline, water depth
• Well data
• Position, name, category, etc
• Well reports
• Post stack seismic data
• All processed 2D and 3D data, velocity data
• Seismic navigation
• Navigation shotpoint position
• Production Data
• Historical and future reporting
• Log Data
• Historical and future reporting

Quality controlled data from NPD, every week
From companies
25
Cultural DataA Cornerstone in the Solution

• Cultural Data supplied by NPD to PetroData

• Registration of all licences
• Operator status and Licence participants
• Share of licence
• Historical Licence Information
• Well IDs
• Pipelines
• Coastlines
• Etc.

26
Digital Reporting Seismic Data

• Processed seismic data in the following versions
  is to be reported
  
• Raw Stack
• Raw Migration
• Filtered Migration
• The naming of seismic lines must be in accordance
  with guidelines (established by Diskos Seismic
  Work Group)
  
• Velocity Data
• Digital Navigation data
• In accordance with Specifications and
  Information for Reporting Navigation Data to
  PetroData see also NPD web site

Diskos Tender Process 2002Operations of Diskos
Database

• Diskos by law had to go to tender
• Bound by Norwegian and European
• New agreement in place 2004
• A time consuming and demanding process
• Committment from the whole of Diskos in this
  work
  
• An important exercise for Diskos
• Operators are in a privilged position monopoly
  issues
  
• Tender process gives the Diskos group valuable
  insight into technological alternatives
  
• The current business model and contractural
  structure will be evaluated and modified

33
Statistics Data Storage

• SINAS currently storage capacity
• Oracle Database 150 GB
• Netapp Disc storage systems
• Total 110 TB.
• 60 TB in use for post stack seismic, logs and
  other small data sets
  
• StorageTek Tape robotics system - 1800 TB of
  storage capability
  
• IBM 3592 Tape technology
• Tivoli Storage Manager (TSM) used to manage Post
  Stack data.
  

34
Historical Well-Data Projects

• Loading of scanned completion reports 1965-1999
• access according to entitlements

• Loading of Scanned Public reports from
  exploration and appraisal wells drilled 1965-1979.

• Loading of well data from 1965 to 1993 to
  transfer data from old media to PetroBank to
  eliminate old input media.

• Loading of indexes for well reports and well
  logs, exploration and development wells 1965 to
  1999
  

35
Lessons learnt in loading legacy data

• Time consuming and costly process
• A lot of manual work
• QC of data input
• Need to understand the data
• Level of quality when scanning
• Are all pages legible?
• Are all pages included?
• Colour vs black-and-white
• Older tape formats
• Difficult to read
• Costly to covert cost-benefit
• Setting entitlements to data was a major task
• Data transfer due to changes in licence
  ownership/participation

Transfer of operations some experiences from
Norway

• Very demanding process
• Can be problems with the previous operator
• Takes focus away from ongoing issues
• Takes a lot of time so the process must begin
  early
  
• in Norway at end of 2002 for 2004 change over
• Need a good spread of expertise
• Technical (data), contractual (tenders, legal
  aspects), software
  
• It is worth the effort!
• Introduces/maintains competition
• Step change in technology
• Revise/improve business model
• Improve/streamline workflows
