In this video, we’ll take a look at how DUG Insight’s novel approach helps you investigate horizon attributes quickly and easily
Lets start by determining what attributes we have available for extraction
We’ve displayed the Top Res horizon in the Map View, by selecting it under horizon in the navigation bar
By default, it will show us the time or depth of the horizon
By Selecting the property dropdown we can see the properties available for extraction
We’re viewing a TWT horizon so most of the properties available are time related
Notice dip direction and strike direction, two depth attributes are listed
These have asterisks next to them as they are currently calculated in time not depth - pseudo attributes
The list of properties will increase as more data is made available to DUG Insight
Let’s add a velocity volume to time-depth conversion
Insight will use the new depth information to calculate depth attributes such as Dip Angle
Notice the asterisk has been removed from dip direction and strike direction
These attributes are now being calculated with the new depth information
Now, select a volume in the volume drop-down
The list of properties has grown as we now have amplitude information
RMS/Amplitude/Peak and trough amplitudes
See our online manual page on horizon properties for a full defination of each of these attributes
We want to perform an RMS extraction on this full stack data
We can quickly select RMS in the property drop down, but, we want to define the window first
Click on the spanner next to property to view the horizon settings
Insight will use the volume selected in the Map View for the extraction, unless a different volume is selected here
The extraction window is defined here
They are relative to the horizon time, we’ll use 10ms above and 50ms below for our example window
These above and below values will be used for any of the horizon attributes that require a window
Select RMS from the property dropdown. Insight will automatically begin the extraction
Insight is multi-threaded and will take full advantage of multiple processors
We can adjust the colourbar and clip while Insight calculates the result for us
Amplitude extractions are run on-the-fly, which means they don’t require disk space to store the results
DUG Insight does have the option to save an extraction, which is helpful when working over a large area, or for more complex, slower attributes
Save the extraction as a property of an existing horizon
To do this, right click on the horizon and select save horizon as custom property
Select the horizon to save to, enter a name, and click OK
The result is now available in the property selector
Insight also offers more complicated attribute extractions, between between two horizons or constant time values
This can be done in the operations tab
We’ll select Amplitude extraction, then the top and bottom horizons -- offsets can be added if working with gathers
Select the volume to extract from and the property
After we click calculate, the extracted results are displayed for review
We can save them as a new horizon or as a property of an existing horizon
Deleting saved attributes is easy
Right click on horizon in Control Panel and select Manage Custom Properties
Right click on the property and select delete. Click OK
