Auscope Project

STATE SURVEYS BOREHOLE HEADER MAPPING

As part of the Auscope NVCL and portal, the Australian States geological surveys will provide access to their borehole databases. We need to provide a mapping between the borehole collars information stored in databases and the GeoSciML's borehole model.

This is a use-case to ensure the Borehole model part of GeoSciML v3 meets the requirements.

CHARACTERISTIC INFORMATION

  • Scope: GeoSciML Testbed 4, Auscope NVCL boreholes and Geoscience Australia petroleum wells

  • Preconditions: State surveys need to have a borehole database already in production. They have to provide us with a flatten view of their borehole collar database if they require our help with the mapping. They also need to provide us with dataset examples for testing purpose.

  • Success End Condition: mapping is done successfully and issues are raised and listed in order to improve the borehole model for GeoSciML v3

  • Failed End Condition: mapping is impossible with the actual Borehole model.

  • Primary Actor: (a role name for the primary actor, or description)

MAIN SUCCESS SCENARIO

step 1: Mapping the PIRSA DB with GeoSciML v2 Borehole model

step 2: collect list of issues encountered during the mapping

  • Note that the mapping assumes schema imports gmd.

step 3: discuss these issues with the GeoSciML community step 4: propose modifications to the Borehole model for GeoSciML v3

RELATED INFORMATION (optional)

Non-Geologic Unit Borehole Mapping

I realise this is not part of AuScope but, the issues we face are similar at a conceptual level. I will be working with a domain expert to map our offshore petroleum wells to the existing Borehole model as we intend to implement a similar model for all holes within GA. As part of our Virtual Data Room project we need to deliver petroleum wells (in the first instance) via WFS/WMS. Attempted to do this last round but, I have resources and a real project this time. smile

  • Additional: Conceptually we would like to deliver the borehole header with basic information about the hole itself. Further information should be available regarding logs of any sort through the OandM model. Lastly a description of the 'borehole survey' that actually describes the hole in terms of its structure in 3D space.

CHARACTERISTIC INFORMATION

  • Scope: GeoSciML Borehole and Geoscience Australia VDR project.

  • What is being tested: Borehole model to non GeologicUnit data. Use of GeoSciML and OandM in combination. I have several hydrocarbon show values at varying depths down a hole that I need to discover which Boreholes they belong to. My GeologicFeature is unknown at this stage because the feature of intrest is the Borehole itself.
    • Additional: Query the Boreholes to determine those with a hydrocarbon show value of > 'L2'. The show is an internal GA determined value stored within the database.

  • Preconditions: more details to be provided by DalePercival

  • Success End Condition:
  1. Mapping Well locations is done successfully.
  2. Issues are raised and listed in order to improve the borehole model for GeoSciML v3
  3. Borehole 'wireline' log can be rendered either graphically or textually.
  4. Delivery of borehole 'survey'.

  • Failed End Condition:
  1. Well locations cannot be rendered.
  2. Borehole features (wells) cannot be searched by (to be defined) attribute.

  • Primary Actor: (a role name for the primary actor, or description)

MAIN SUCCESS SCENARIO

  1. Mapping the GA Petroleum Wells to GeoSciML Borehole & OandM
  2. Delivery of wireline logs
  3. Query a MappedInterval depth where a hydrocarbon exists to discover which Borehole it comes from

Use Case Notes: Do we need to update the model to allow the bi-directional query for a Borehole from a MappedInterval?
