Composite and Model Qualities / Coal Compositing
Use Coal Compositing to produce a composite for any specific interval down a hole. The composite interval (the structure) can be defined by geology, height, surfaces, or a combination of these. Analytical data can be extracted from multiple databases using depths or samples.
The composites can be output to a standard mapfile, a CSV file or a composite database.
Instructions
The Coal Compositing panel uses a tree interface. Select branches from the tree menu on the left and make your selections from the different panels as described in the instructions.
Select Grid Calc > Integrated Stratigraphic Modelling > Composite and Model Qualities to display the Coal Compositing panel.
The Coal Compositing interface consists of the following key sections:
Specifications
Use this section to create or load a Coal Compositing specification file (.ccp
). This file is where the changes made on this panel are saved.
Structural Data
Use this section to set up the database that contains the structural data for the hole such as the collar and the downhole survey and lithology. The schema is populated automatically with the synonyms from the design database.
Horizon List
Use this section to define a horizon list file which can then be used in other sections of the panel when selecting horizons to be composited. This horizon list can be standard Vulcan GLOB file (as used in GDCALC) or a horizon file of your own making. The GLOB file has a defined format, but the horizon list file format can have a number of lines with each line having comma, space or tab separated horizon names in it.
Product/Waste
Use this section to use rock codes to define the product and waste if you have setup a rock code field in the structural schema as well as the Lithology Codes section.
Structure Definition
Use this section to define the top and bottom of the structure that will be composited for each hole. The various methods all produce a top and bottom downhole depth per hole.
Analytical Data
Use this section to define any analytical source that you will be compositing, such as a database that contains a field that you want to composite.
Conditions
Use this section to apply conditional expressions to the data used in the coal compositing operation.
Output
Use this section to output composited variables to a standard mapfile, CSV file, or composite database.
Save
Use this section to save any changes to the specification file and to run the compositing.
The following buttons are displayed throughout the Coal Compositing interface:
Clear
Click this button to clear all entries in the Coal Compositing interface -- including those in other panels.
Apply and Run
Click this button to save the entries before performing the compositing run. Once selected, the Coal Compositing interface will be hidden temporarily and the compositing run is performed. If a compositing run is cancelled, you will need to confirm that you want to interrupt the compositing run before the interface can be displayed again.
OK
Click this button to save all entries before exiting the Coal Compositing interface or moving to the next panel.
Cancel
Click this button to exit the Coal Compositing interface without saving any settings.
Make selections from the Specifications panel to begin the process.
Specifications file
Select the Coal Compositing specification file (.ccp
) that you want to open. The drop-down contains all of the .ccp
files found in the current working directory.
Audit details
These fields are automatically populated if the nominated specification file has any modification history. The Created on/by an Last modified on/by fields are read-only, and cannot be modified.
