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 project milestones l.jpg

DISKOS project milestones

  • Project started in 1992

  • Operation started 1995

  • Revised business model 2000

  • Change of operator 2004


Diskos basics l.jpg

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”


History the diskos project l.jpg

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


Issues l.jpg

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


Diskos organisation l.jpg

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!

Digital reporting seismic data l.jpg

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 2002 operations of diskos database l.jpg

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


Statistics data storage l.jpg

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.


Historical well data projects l.jpg

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 1993to 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


Lessons learnt in loading legacy data l.jpg

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 l.jpg

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
