Stochastic Rock Physics Model Overview

The QI tab hosts the Stochastic Rock Physics Model window, which is a stochastic interface modelling tool. Stochastic Rock Physics Model replaces the legacy Distill module and integrates seamlessly and interactively with the Insight crossplots and lithofluid workflows.

Using end-member depth-dependent trends as input, multiple lithology and fluid combinations can be created and stochastically forward-modelled. The ability to discriminate between different combinations and the variation in response as a function of depth and other variables, including reservoir quality and fluid saturation, can quickly be assessed using Stochastic Rock Physics Model. 

Available in: Lithofluids module.

Prerequisites

End-member trends

Stochastic Rock Physics Model requires end-member trends to be loaded in the session.

End-member trends can be imported from files generated by DUG Rock or by other software with extensions *.trend, *.txt, *.prn or *.asc. For more information on trend files, refer to Using Rock-Physics Trends.

Adding a Stochastic Rock Physics Model

  1. In the Control Panel, open the QI tab.
  2. At the tab header, click on the Add icon and select Add Stochastic Rock Physics Model.
  3. Type a new name for the process, and click OK. The Stochastic Rock Physics Model window will now be displayed. See Using the Stochastic Rock Physics Model for a description of all the tabs in the window.
