DISKOS database

The concept of a national data repository was conceived in 1992 by NPD and the three Norwegian oil companies Hydro, Saga and Statoil.

Data of known quality delivered on agreed data formats Official quality approved cultural data from NPD Seismic and navigational data Well data Production data Archive data The NPD and the majority of the oil companies who operates on the

Norwegian continental shelf have direct online access to the database Non-members can purchase data on media There is strict control of all access rights to the database

Workflow for new Norwegian Seismic

Orders from O&E organization for a new seismic survey Geophysical Operations are responisible Seismic survey (segytapes,navigation & velocity) are send to SINAS

for loading into the DISKOS database (Petrobank) and owner rights for Hydro are updated

If survey already is in DISKOS database , SINAS set owner rights for Hydro after email from contractor

New PGS Spec surveys are only available in LANDMARK database (old DISKOS database), here we download segydata (survey) & navigation to disk or tape and send this to SINAS for loading into DISKOS database

Geophysical Operations inform O&E organization that new survey is in DISKOS database (Petrobank).

O&E organization must place an order to IH (Information & Ordering database)

Old Workflow for International seismic data

Orders from O&E organization for a new seismic survey Geophysical Operations are responisible Seismic survey (segytapes,navigation & velocity) are send to

Geophysical Operations Geophysical Operations inform O&E organization about shipment O&E organization make a order to IH (Information & Ordering

database) Media (tapes) are send to IH for loading into Geoframe Tapes are returned from IH to O&E organization Tapes are stored at G&G person office or send to Geotjenester for

archiving

IS Project ”International seismic to Petrobank”

In 2003 Hydro started internal discussion to find a better solution for managing international data

WHY ! Norsk Hydros internationale seismic database is growing. Times with high turnaround, and a lot of changing in the organisation. Each Business Unit manage seismic data differently Many storage solution ; Petrobank solution (Petrodata), Tape archive

(Geotjenester), project database (Geoframe), corporate datastore and ”shelf and cabinets”

G&G want one common GIS view for seismic,navigation & velocity No standard data management routines has been established

Date: 2005-08-18 • Page: 15


- GOAL Make ”Petrobank” a primary datasource for Navigation,Velocity and

Seismic Same solution as for the Norwegian DISKOS database Use same routines internally as established and approved by the O&E

organisation operating on Norwegian continental shelf Increased access, backup of data , quick and easy overview Commen graphical user interface All 2D/3D navigation combined gives a far better overview and a very

good startingpoint for new areas To be able to handle the navigation challenge international (datum

problems)

Date: 2005-08-18 • Page: 16


- EVALUATION PROCESS Total datavolume seismic (around 2,7 Tb ) 2D/3D surveys (around 1500 ) Based on two written offers: SINAS (Schlumberger) and PETRODATA SINAS - Maintenance must be paid to Landmark if SINAS (DISKOS)

Petrobank will be used for international data PETRODATA - Have their own license which can be used Technical advantages - Both can connect to other internal oracle DB’s

by PowerExplorer After a long Internal discussion we choose SINAS

Late 2004 Hydro decided to start the project A steering group and a project group was establish The work will be perfomed by IH ,Geotjenester and SINAS Collect international navigation/velocity and seismic data on tapes at

Notodden (Tapemaster), in Finder and Geoframe. Store this data in international database (Petrobank) The work will be performed according to the steering groups priorities

as long as the budget last Priorities will be given by the business according to the followings: 2d navigation all areas Stacking velocity all areas 3d navigation all areas 2d/3d seismic priorities areas The quantity of 2D and 3D navigation, velocity and seismic are

investigated area by area as the project rolls forward. Therefore we do not know how much we manage to transfer at the start of the project.

Project schedule

Initial activities/kick off performed

PHASE I - TRANSFER NAVIGATION TO PETROBANK Transfer 2D navigation Prioritize further work (seismic/velocity/3d navigation) Decision in Steering committee

PHASE 2 – VELOCITY,3D NAVIGATION,CORRECTIONS Fixing 2D navigation problems Transfer 3D navigation and correcting nav. prob. Transfer 2D & 3D velocity

PHASE 3 – PREPARE SEISMIC TRANSFER Detail overview over scope of seismic transfer Budget for next year (2D/3D seismic) Final QC – Update TapeMaster Close down project (within 30/12)

New workflow for international data

Orders from O&E organization for a new seismic survey Geophysical Operations are responisible Seismic survey (segytapes,navigation & velocity) are send to SINAS

from contractor or Geophysical Operations Hydro QC data after SINAS has finished loading data into Hydro

international ”Petrobank” database Owner rights for Hydro set by SINAS after email from O&E Geophysical Operations inform O&E organisation about new survey

in Hydro International ”Petrobank” database O&E organisation makes an order to IH (use the Information &

Ordering database) for loading survey into Geoframe Hydro QC data in Geoframe and rate IH job

Hydro International ”Petrobank” database

Status Today Loaded around 1000 2D Geometry sets Started loading 3D Geomerty sets into Hydro International

”Petrobank” database Two successful cases :

- Discovered new surveys in working area- Avoid buying seismic survey twice

Future Work/Wish-list Backlog seismic surveys after a prioritized list (2006) Make standard AOI view in PowerExplorer for all international areas Load international culture data Load international wells into Hydro International ”Petrobank” International Spec. Data in DISKOS database with strict control of all

access rights to the data
