[OpendTect_Users] Asking about how to build a synthetic model

[Farrukh Qayyum]

Dear Soni Satiawan,

If you are interested to create a geologic model, you can build it using 
two ways:

*Method 1:* _Volume Builder_
/A simple layer based coarse geologic model.

/OpendTect's volume builder allows you to create a horizons based 
geologic model. A simple model that you can think of is a model of 
n-layers bounded by several interpreted horizons. Such a model is 
constructed in OpendTect using the*horizons based painting* step 
available under the Volume Builder toolbox. If you are interested to 
know more about this, please take a look on the following webinar.

http://opendtect.org/tutorials/Webinar_Volume_Builder/

For further details, I will suggest you to read and follow the relevant 
Help documentations by clicking on the Help icons available on each dialog.

*Method 2:* _HorizonCube + SSIS_
/A detailed geologic model based on sequence stratigraphic interpretation.

/Another way of creating a geologic model is to create a HorizonCube 
<http://www.dgbes.com/index.php/articles-horizoncube.html> and 
sub-divide the cube into sequence stratigraphic units (sequences, 
systems tracts, or parasequences). For sub-divisions we use SSIS 
<http://www.dgbes.com/index.php/articles-ssis.html> tools. Once this is 
done, you have already created a 3D volume that defines the 
stratigraphic units in 3D.

All you need initially a model that contains layers. Once the layers are 
defined, you can use logical expressions in Mathematics (or Neural 
Networks) to combine the seismic attributes (e.g. curvature for 
fractures) per or for certain layers. As you mentioned you are 
interested in fracture orientations and their density, you are probably 
looking for curvature, dip and azimuth types of attributes. Please note 
that OpendTect supports a series of curvature attributes (over 10).

If you or others have more interest to dig these tool in details, please 
do not hesitate to contact me directly.
