PETROG v.2
=========

There are 3 projects included with the demonstration program:


PROJECT 1: "Compositional data demo" (Data entry and editing)

This has been provided as a quick introduction to the the heart of the PETROG system - thin section point counting.

This project contains 3 samples in 1 well:

- Sample 1000m

Sample 1000m has data from both textural and compositional analysis, together with some example images. The data is only for demonstration purposes and is not meant to represent a real rock sample!  The images also are just for example purposes and any correspondance with the data is purely accidental.

This sample can be used to see the capabilities and functionalities of the data review and edit functions, under the Data Edit and Data Review 
main window menu options.


- Sample 1005m
Select sample 1005m using Sample -> Set Current Sample (see section Sample in Help/Manual)

Sample 1005m has a set of example images attached which can be used to practise the entry of quantitative compositional data, without having a camera and video frame-grabber.
Select menu option:
Data Entry | Composition - Quantitative

Start logging by selecting from the (adaptive) menus on the right of the screen, to describe the images on the left of the screen - in a "live" environment, these images would be showing exactly what is seen through the microscope eyepiece. When you have fully described them, the images will change, just as in a live environment the stepper moves the slide to its next point.

Select Data Entry -> Composition - Quantitative (see section Data Entry in Help/Manual).

The example images can be re-used by resetting the Sample Status to Not Started, using Admin -> Sample Status (see section Admin in Help/Manual).


- Sample 1010m 

Sample 1010m has only the basic sample details defined.

This sample can be used for practising the definition of a sample and associated data.



PROJECT 2: Ternary diagram demo

This project uses data from Weltje, G.J., "Quantitative analysis of detrital modes: statistically rigorous confidence regions in ternary diagrams and their use in sedimentary petrology",  Earth Science Reviews 57 (2002) 211-253 (with permission) to demonstrate the support offered within PETROG for analysis using ternary diagrams (triangular diagrams).

Change to this project using menu option

Project -> Open Existing Project

then select:

Data Review -> Ternary Diagram



PROJECT 3: XRD data demo

XRD data can be imported into PETROG from various standard and proprietary formats. The clays counted during compositional logging within PETROG can then be compared with the XRD-determined clay content, correcting respectively for having measured volume and weight as well as correcting for variable microporosity content. This analysis therefore provides yet more feedback into microporosity determination.

Select:

Data Review -> XRD Comparison

to see one sample at a time click Next / Previous buttons to step through all samples) then select:

Data Analysis -> XRD

to see all samples compared.



IF YOU GET STUCK!
-----------------

1. READ THE MANUAL/HELP, section Getting Started.

2. READ THE MANUAL/HELP for the section that you are having problems with.

3. E-mail us (DemoSupport@Petrog.com) with a detailed description of what you are trying to do and what went wrong.  We will try to get back to you as soon as possible, but the more detail you give us, the more likely it is that we will be able to sort out the problem quickly.

If you do encounter a software problem, it would help if you send us the debug file (debug.txt on the ~\Petrog install directory).

To make sure that this is created in detail, turn on debugging (if it is not already on) by clicking the radio-button menu option:

 Admin -> Debug listing -> Debug listing enabled

and then repeat the (minimum) sequence which leads to the problem.
