Benefits of the SSDM?Benefits of the SSDM?Three main benefits for individual organisations:

Provides a template for survey contractors to deliver data to The ESRI geodatabase is scalable to the corporate database level Consistent presentation and query processes can be performed on the data

Flow on benefits if an industry standard model in place:

Simpler data exchange between companies and/or joint venture partners A single data model for survey contractors to deliver data to All survey contractors would need to elevate their GIS capabilities in order to deliver seabed survey data to an industry expected standard

VISIONVISION

“For the industry to have a template/standard for how seabed survey data is delivered to and

managed by oil and gas companies”

HistoryHistory

Seabed Survey data now supports increasing range of tasks:

• Field development planning (deeper water, increasingly complex geology, topography)• Well design: sub-surface to surface• Seismic: identification of multiples• Environmental monitoring • Operational support (anchor planning)

Previously no industry drive to develop an industry wide delivery standard for seabed survey data. This has:

• Put added pressure on survey contractors• Increased data management effort for data management teams• Made it difficult to seamlessly integrate data• Made it difficult to share data between joint venture partners

What is the Seabed Survey Data Model?

The Seabed Survey Data Model is an ESRI Geodatabase GIS data model capturing:

1. Seabed features, Seafloor/Subsurface geologic hazards features interpreted from offshore analogue and digital site survey, sweep/debris survey and pipeline route survey.

2. Survey navigation data and Survey Keysheet (Project Extent)3. Database tables of survey records inventory and document management.

The Work So FarThe Work So FarFoundation Work:

• 2006 - Shell workgroup released version 1.0.• >40 surveys delivered for Shell in Asia (site, sweep, pipeline route, pipeline surveillance surveys)• Reviewed with several survey contractors.

• 2009 – Reviewed by Woodside & other Shell operating units

• 2009 – Shell released Version 2.2 based on the Woodside gap analysis and feedback from other Shell operating units

• 2009 – Shell technical specification released (TS-303 Spatial Data Deliverables) for data deliverables

• 2009 – Woodside pilot project undertaken• 2010 – Woodside technical specification released (GMS-

010) for seabed survey data deliverables• 2010 – Specifications now being embedded in survey

contracts at Shell and Woodside

Industry Activity:

• Oct 2009 –Seabed Survey Data Model paper presented at OGP Surveying & Positioning Committee by Woodside

• Oct 2009 – OGP agreed to take forward the Shell/Woodside development to produce an industry standard data model

• Jan 2010 – OGP Survey and Positioning Committeesetup the Seabed Survey Data Model Task Force

• Feb 2010 – ESRI Petroleum User Group conference presentation by Shell entitled Seabed Survey Data Model: Maximising Value in Houston

• May 2010 – Developing a GIS Data Model for Seabed Site Surveys paper being presented by Shell at the Offshore Technology Conference in Houston
