Editing input data Problem Areas
Imported data will often need someediting to make them suitable for
modeling
Examples:
Irregular 2D Grid that needs
smoothing
The 2D grid or seismic
interpretation might contain
spikes
Fault polygons might miss Z-
values
Line data that has been imported
without a “flag value” indicating
line segments => flags must be
inserted to split the lines.
“Bad” data can be eliminated

Editing input data Make/Edit Polygons process
Create new polygons
Create new line within
existing polygon
Close polygons
(Must be active before
closing polygons)

Editing input data Make/Edit Polygons Process
Edit polygon points byusing Edit/Add points
1. Select the point to edit
and move it
2. Create a new point byclicking on the line in a
polygon and move the new
point that will appear.
Edit polygon lines by using
Edit line
Disconnect polygons

Editing input data Operations and Calculator
1. Right-click on the file‟sname and select Settings
2. Go to the Operations tab
The files are typicallylines, points or 2D Grids.
All operations under the
Calculator are also
available from the
Operations tab.3. Select the appropriate
operation
• Polygon Operations are used for doing
operations on existing polygons, and on all
points belonging to the polygon.
• Make/Edit polygons process: Option to createnew polygons, split them at the desired
position, editing each single point and line by
clicking and moving. Interactive editing.

1 – Enter the data to be gridded (If this
is well tops, choose the Attribute)
Make Surface is the process of gridding
lines, points, well tops, fault cuts, and2D grids, to produce new 2D grids
2 – Give a name to the output. Default
is the same name as the main input.
3 – Define the Geometry
4 – Click on „Suggest settings from
input‟ and select type of input data. Use
the settings suggested or define your
own under Algorithm
Optional: Use boundary, well adjustment
