Faster Data Loading for Large 3D SEGY and Grid
Models: When scanning or rotating very large 3D
SEGY or grid model files the system response is sometimes slow.
To speed up the display for these data sets, a new data loading
option has been added. When using this option, the program will
display two slices through the volume. For SEGY volumes, there
will be vertical x-plane and y-plane slices through the center
of the model. For grid models there will be a horizontal
z-plane and a vertical y-plane slice through the center of the
model. These planes can be scanned through the volume with
controls located in the property dialog. The third axis plane
can be turned on from the property dialog but the display will
be slower. To load files using this option, select File/Open
Large 3D SEGY File. |

|
Scan Large 3D Volumes: Scanning for large 3D SEGY or
grid model volumes is now automatically limited to one axis at a
time. When one scan is started, the scan buttons for the other
directions are disabled. When the scan is stopped, all buttons
are restored and any single scan can be selected |

|
Depth to Time Conversion for Well Logs: The
depth to time conversion for well bores has been modified so
that the well logs can be converted at the same time. The input
and converted output well log file names are simply added to the
.3welZ/.3welT dialog to include the log curves in the
conversion. The output log curves will have file extension
.logT or .lasT depending on the format the input
depth log file. |
|
|
|
New ASCII Well Log Format: A new ASCII well
log format has been added. This new format requires a single
header record, which contains the log curve names. The curve
values are in columns with one set of values per line. The
first column must contain depth. The file type for this new
format is .log and the file is loaded in the same manner as LAS
formatted logs. |
|
|
|
Well Names Displayed at Wellhead: Well file
names are now displayed in the scene next to the wellhead. The
label can be turned on or off from the Wellbore property
dialog. The color of the label can also be changed from the
Wellbore property dialog. By default, well name labels are off
unless a well list is used to load the wells. |
|
|
|
Multiple Log Curves Display: Multiple log
curves can now be displayed for any well. Selecting the curves
to display is still done from the Wellbore property dialog
except that you can now pick more than one curve. Use the Shift
key to select a group of curves that are adjacent to each other
in the list. Use the Control key to select any curves from the
list. The display for any curve can be changed as before
opening the Log Curve property dialog for that curve. |
|
|
|
Free Format Well Geometry: Directional
survey wellbore information can now be loaded from third party
ASCII files. The only restriction is that the input file
contains one set of coordinates (X, Y, and Z) per line. If you
have multiple wells, they can be loaded together at the same
time. The program assumes there is one well per input file.
The new well data loader can be accessed by the File/Import Free
Format Well pull-down command |
|
|
|
Well List File for Loading Multiple Wells: A
new VISUS file type has been created to speed up the task of
loading multiple wells. This new file contains a list of wells
and log curves that can all be loading by simply loading the
file list. The well files can be in either VECON or a third
party ASCII format. If available, the log curves for the wells
are loaded at the same time. The well file list file is
identified by an extension of .dat and can be loaded by either
File/Open or the Open File icon |

Grid Cell Control for Import Interface: Loading of ASCII
x, y, z interface data could give unsatisfactory results if the
layer grid cell size was not chosen properly. The defaults and
user control for grid size have been changed to address this
issue. When loading the ASCII interface file, the program first
scans the data points to determine the lateral extent of the
layer. The default grid size is set so that there are 100 grid
cell in either x or y, which ever is larger. Since the grid
cells are square, there will be smaller number of cells along
the other axis. If the imported layer has holes or gaps, the
number of grid cells should be decreased. If the imported layer
is too smooth, the number of grid cells should be increased. To
change the number of grid cells, open the Configuration dialog
and change the Layer/Max. Grid parameter. |
