Introduction
This presentation will introduce you with the HorizonCubetools that are used to manipulate an existing HorizonCube.
The manipulation includes the followings:
-Fill the gaps in a HorizonCube by adding more iterations.-Truncate a HorizonCube to get a better Wheeler Diagram.
-Add a new Horizon to an existing HorizonCube to introduce an additional package (or a
sequence).
-Re-calculate a HorizonCube (or a package) by changing a SteeringCube.
-Extract seismic horizons from a HorizonCube.
.... And Much more.

HorizonCube ToolsAdd more iterations...
To fill the gaps in a HorizonCube (red arrows), we suggest to add moreiterations i.e. track horizons in a gap that is being found in a package.

How To...
1. Select the Input HorizonCube first and always
output the HorizonCube with a new name.
2. Select the additional iteration that
you would like to add e.g. 1. If youstill find gaps in this new
HorizonCube, then do the same
steps again.

How To...1. Display a HorizonCube first and then use this menu.
2. Move the slider (Top/Bottom) at a location where you
want a horizon.
3. Prese the Pick Horizon button to save a horizon at a
selected slider position. You can pick more than one
horizons (repeat steps: 2-3).

Why?
The HorizonCube can be data driven and as well as model driven. This makes it
more important especially in terms of filtering the seismic data along the
automated horizons geometries. Thus, you might want to create a model based
HorizonCube to create a SteeringCube out of it and filter the seismic data based
on a modelled based SteeringCube.
Further application could be the curvature/dip attributes analysis using a
SteerignCube created from a data driven HorizonCube.
An overlay of SteeringCube (white-red) on the
seismic data. This SteeringCube is created
from a modelled based HorizonCube.

How To...1.Select the input HorizonCube.
2.The dip outside a HorizonCube can be set to undefined (type undef in the dip value field) or
leave the dip value to default (0).
3.Type the output name for the SteeringCube.
4.Press Proceed, this will start the batch processing.

HorizonCube ToolsTruncate HorizonCube...
The selected input HorizonCube is truncated by removing the areas that define the allowed
horizons density i.e. Maximum density. The maximum density value refers to the number ofevents within a seismic sampling rate. For instance, if you observe that you have 5 events
in a 4ms sampled data, you would probably want to remove those unwanted area.
Geologically, such regions of closely spaced horizons are often unconformities, pinchouts,
condensed intervals, and even the leeves (and/or the bottom) of a channel.

HorizonCube ToolsTruncate HorizonCube...
The truncated HorizonCube can be used for a better Wheeler Domain visualization and
thus the subdivision of sequences into systems tracts. The example below, shows acomparison of Wheeler Diagrams of porosity volumes. Both diagrams are automatically
transformed using two types of HorizonCube(s).
Suggestion: For sequence stratigraphic interpretation, it is recommended to truncate a
continous HorizonCube.

To upgrade the ChronoStrat computed in the previous versions
(earlier than 4.0) into a HorizonCube, you may use this tool.
How To...
Select the input chronostratigraphy created in older version, and write the
output HorizonCube name.
