Geoscience Reference Data

You can create and store Geoscience reference data and further use it in downstream processes.You can define three types of Geoscience reference data: Attributes, Interpretations, and Measures.

Example of Attribute/Methodology Pair

Borehole data values that you import to the 3DEXPERIENCE Platform are saved as an Attribute/Methodology pair (See Geoscience Attributes and Methodologies). For example, in BH01 for the attribute Gold, the interval from 24.5 to 25.6 meters has a measured value of 0.3, which is calculated using the methodology Fire Assay. After importing to the 3DEXPERIENCE platform, the value is saved for both the defined attribute and methodology. BH01 for the attribute Gold and the methodology 3 meter Downhole Composite, for the interval 24.0 to 27.0 meters has a value of 0.7, and the values are saved accordingly. When the data is stored in the 3DEXPERIENCE platform, you can determine that both values are for the attribute Gold, but one attribute is measured for Fire Assay methodology and the other is for a Downhole Composite methodology.

Types of Methodology

There are two types of Methodology: Measures and Interpretations. Measures are values of observations, from a direct or known process. Assay values, geophysical measurements, and observed rock types are examples of Measures methodologies.

Interpretations represent data that is created through a process applied to measured data. For example, compositing is an interpretation of measured assay data. The interpretation methodology subtype allows us to record the values observed using the interpretation process (the composited values), and also the specification of the process that gives us the interpreted values (the compositing parameters for the composite values). The benefit of storing both the values of an interpretation and the specification means that we can (a) examine and audit the process and parameters used to create the interpreted data, and (b) quickly and easily re-use the interpretation parameters later, in the case that we receive additional or updated borehole data that should also be interpreted using these parameters.

When defining an interpretation, only create and name a place holder for the interpretation. You can define the specification for the interpretation only when it is used to create new interpreted values.
