IMPORTANT NOTE! For details, please
refer to the manuscript titled "A Computer Program for Practical
Semivariogram Modeling and Ordinary Kriging: A Case Study of Porosity
Distribution in an Oil Field" submitted for publication in OPEN
GEOSCIENCES JOURNAL in May, 2017. SETUP
INSTRUCTIONS FOR JEOSTAT_2017.0 Step
1. Click
and download the JeoStat_2017.0 setup file to local disk (For example: C:\Users\Desktop) Step
2. The JeoStat_2017.0 file includes setup file to
install the JeoStat. Step
3. Please
click the setup file to install JeoStat to local drive. Step
4. When
installation is complete, please run the JeoStat from the Start menu or Start
screen. Step
5. The
JeoStat_2017.0 setup file includes Sample
Data file to perform demo analyses, please check the data file or prepare
an ASCI file (*.txt,
*.dat, *.csv) with headers lines followed by the data as a tab or a comma
delimited. As shown below, the first header line is title. The second line
should be a numerical value specifying the number of numerical variables in
the data file. The next lines contain character identification labels. The
following lines are considered as data points and must have numerical values
per line. Step
6. JeoStat
main application form includes six tab screens. Please perform these analysis, respectively. Importing data Step 7. Click the Input
File button to load data file to JeoStat and select the data file from
the Dialog Box 1. Define a path and file name for the saving of
results to the local drive from the Dialog
Box 2. The path and file name is very important for the user, because the
file name will be saved into the hard drive with various file extensions such
as .stat for statistical analysis results, .var
for semivariogram analysis results, .res for cross validation results
and .grd for kriging results. Step 8. Select and define variables
required for the X (easting), Y (northing), elevation, variable label,
dimension of analysis and transformation options from the combo box
components and click the Read Data
button. Statistical Analysis Step 9. Please Calculate and Plot button to compute
and show up the statistical analyses results. Semivariogram Modeling Step 10. Please, firstly, input
direction angle, tolerance angle, increment and number of lag to the related
input box and then click the Calc.
Experimental Semivariogram button to show up the Experimental
Semivariogram on the picture box. Step 11. Please select the variogram
model type from the combo box firstly, then click and move the mouse on the
picture box. Then click the Apply
Semivariogram Model button. Cross-Validation
Test Step 12. Please click
the Cross Validation button and
move the mouse on the Picture Box to show up Kriged
and Observed value. Kriging Estimates Step 13. Please insert the grid sizes and other kriging parameters required for
analysis related to the text boxes firstly, and then click the Start Kriging button to estimate values of grids. Step 14. Please, firstly, check the Grid Node Editor and select the *.krg
extended output file relevant that variable. Then, click and move the mouse
to show up the estimated value on the labels. Visualization of the
Otputs Step 15. Please, fistly, click the Map Analyses button to contouring map
on tab screen. Then, input a value for the contour interval to the text box
and click the Refresh button to
show up the map. If you see the contour value on map, please, click the Grid Node Editor and select the *.krg
extended output file relevant that variable. Then, click and move the mouse
to show up the estimated value on the labels. |
