Introduction of VORP
What is VORP ?
The name VORP stands for Visualization
of Reservoir Properties. It is a new window application which
allows geologists and geophysicists to easily visualize subsurface
reservoir parameters in 2 and 3 dimensions and to easily create
their own animation pictures showing the spatial distribution
of reservoir properties in the subsurface. The VORP is written
based on MATLABs matrix functions and graphics objects. The VORP
is developed by Michigan Technological University under the DOE
contract.
Why do we use MATLAB to create VORP ?
The VORP is written under MATLAB environment,
that is, the VORP is a new application of MATLAB in geosciences.
We choose MATLAB as a tool to develop VORP because MATLAB is a
technical computing environment for high-performance numeric computation
and visualization. Some important advantages taken from MATLAB
for this project can be generalized as follows:
1. MATLAB, referring to matrix
laboratory, present the-state-of-the-art for matrix
computation. To visual subsurface geological features and reservoir
properties in 2 and 3 dimensions, geological database (data structure)
has to be reconstructed into different forms of matrix . This
difficult job can be easily handled in MATLAB environment.
2. MATLABs graphics system provides a variety
of sophisticated techniques for presenting and visualizing data.
By creating and manipulating MATLABs low-level graphics objects,
an independent visualization application in geosciences can be
possibly built up and can be easily used by geologists and geophysicists
who have less computer experience.
3. MATLAB is much chipper than other graphics
software in cost. Especially, once the MATLAB executable compiler
is available, our new application, VORP, can be directly run in
the MS-DOS and Window environments without relying on MATLAB window
environment itself.
4. MATLAB based graphic application can be
run in different platforms SUN/UNIX,
Macintosh, and MS-DOS without changing a single
code. The flexibility is very competitive.
How does the VORP work ?
The VORP is a project-oriented graphic user
interface to visualize geological and geophysical data in 2 and
3 dimensions. Users can create their own project to specify their
studying interests. Currently, the VORP has to be run in MATLAB
Command Window although the compiler will be available soon for
this project.
At the VORP directory in the MATLAB Command
Window, users can start the VORP program by typing: runvorp. Then
the users can follow the menu-and-button controlled instructions
to create project and to do their visualization studies. An attached
flow chart shows how the VORP graphic user interface is modularized
and what kinds of functions that the VORP can offer to users (Figure
1). User can always get on-line help from the working window by
click About button or the head of the menu. One of important properties
of the VORP is that input and output data files are in common
text format that makes geological data preparation, correction,
and conversion much easier.
What can be done in the VORP ?
Both geological properties and well logging
properties can visualized in the VORP menu windows. In the VORP
menu window, users can accomplish following tasks:
(1). Data Processing --- includes
data filtering to keep all data points can be properly
grided without any identical data pair; data girding to
create equal distance 2-D and 3-D data structure (matrix); load
faults and add faults to integrate the faulting feature
into data structure of the reservoir property visualization, if
any faults are involved;.
(2). 2-D Visualization --- Different
types of contour maps can be visualized and the well information
can be easily identified from the contour maps. A cross-section
between any two points can be easily picked up from the contour
map and visualized in 2 dimensions and 3 dimensions.
(3) 3-D Surface Visualization ---
Different types of surface maps can be reviewed from any viewpoints
(elevations and azimuths cab be easily changed) in 3-D dimensions.
You can also identify any wells and integrate faults in the 3-D
surface map.
(4). 3-D Slice Visualization ---
First, using 3-D data processing modular to create (X,Y,Z,V)
data structure for a particular reservoir property from different
depth intervals ( or multiple layers). Then, user can create a
solid body which shows a real 3 dimensional distribution of the
reservoir property. It is very unique that the VORP can let geologists
use slicing visual tool to slice the solid body into pieces
in different directions and different shapes to investigate a
continuous change of the reservoir properties at a particular
angle in 3 dimensions.
(5). Animation --- User can snap
any 3-D visualization picture that is created in the VORP and
save it as a movie. At on-site shooting, some important
options such as number of frames and shooting speed can be controlled
as users wish. User can make a series of movies for a particular
project and consequently build up a project cinema. In
a project cinema, names of all animation pictures are listed in
the order that user prefers. And all movies can be replayed by
clicking the name of the movie. How many times and how fast that
movie is played can also be easily adjusted by user.
(6). Well Log Studies --- In the
VORP window, user also has an opportunity to do some well log
studies which includes :
Log Curve Review
allows user to review up to 6 kinds of well logging curves at
any depth intervals: SP log, gamma ray log, resistivity logs,
density log, neutron porosity log, and sonic log.
Cross-Plots
allows user to plot any pair of logs listed above at any depth
interval.
Syntheticgram
allows user to create a syntheticgram using either SP log or gamma
log along a line that user draws on a regional map .

geological data processing which mainly deals with filtering and
griding raw data and calculating 2D and 3D distribution of the
faults, if necessary.
¨ Click
Data Filtering button to let user to start pre-process
the raw data. Sometimes, the raw data can not be directly gridded
because there are some data points are 'identical' so that MATLAB
won't execute data gridding. The input data is in ASCII format
with extension .dat. For Example, if you have 3 variables
X, Y, and Z, in your data file, the format will be:
123.2 23.8 -9.0
125.1 24.3 -7.5
....... ...... ......
¨ Click

feature need to be visualized.
The fault data file contains FOUR faulting
elements which are needed for fault calculation and visualization:
X-Axis (Longitude, Surface Coordinate E, ect.), Y-axis (Latitude,
Surface Coordinate N, ect.), Fault offset (hanging wall dislocation
against foot wall: the negative number means reverse fault and
the positive number means normal fault), and Slop (horizontal
dislocation at every 100 ft in depth).
Example:
-119.2041 35.0137 80 0.50
................ ............
..... ..........
-138.4500 45.9845 -56 0.10
The VORP can handle up to 10 faults for one
project.
Output Data Size
is the number of fault points which you prefer in the "Output
Data File". Sometimes, the fault points identified from subsurface
are very limited, but the VORP allows user to insert as many points
as needed to fit the structure griding size.
¨ Click
