QI Stochastic Model Overview

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

Using input end-member depth-dependent trends, different 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 QI Stochastic Model. 

Available in: Lithofluids module.

Prerequisites

Data Input File

QI Stochastic Model requires source files of rock physic trend file output from DUG Rock with extensions *.trend, *.txt, *.prn or *.asc to load as trend files into DUG Insight. For more information on trend files, refer to Using Rock-Physics Trends.

Adding a QI Stochastic Model

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