DEMO03 - Plot Model, Receiver Well, Source Well
Here we have plots of the model, receiver well+geophone locations,
and source well+source locations. Four records have been added to
PARAM1...
syncline :model file
4 :#interfaces in model
plotcolors :model colors file
m :first plot descriptor (mq)
rwell :receiver well coordinates
wg :receiver plot descriptor (wgq)
d :shooting mode (dg)
swell1 :source well coordinates
don't care :file containing coords. of sources
wsq :source plot descriptor (wsq)
First, in Record 7, is the shooting mode. This is either d, for
downhole, or g for general. The receivers are always located inside
the receiver well, but there is a choice for locating the sources.
In downhole mode, the sources are distributed throughout a source well;
thus, we must provide a source well description (see below).
The name of the file describing the source well and source locations
is given in Record 8 of PARAM1.
In the general shooting mode (Record 7 = g) the sources are not
confined to a well, but can be anywhere in the model.
In this case, a file containing a list of the source (x,z) coordinates
is provided. The name of the source file is given in Record 9 of PARAM1.
(See Demo06 for an example of the general shooting mode.)
Record 10 of PARAM1 is a plot descriptor for the sources. Enter
w here to get a plot of the source well, s for the source locations,
and/or q to quit at this point.
Format of the Source Well File (Downhole Mode)
----------------------------------------------
The format of this file is the same as that for the receiver well:
3000. :x-coord. of top of source well
5000. 6000.
1. -99999. :end of source well definition
500. :depth to first source
1 500. :#sources, source spacing
Format of Source Description (General Mode)
-------------------------------------------
This file simply contains a list of source locations:
x1, z1 :location of source 1
x2, z2 :location of source 2
...
...
xn, zn :location of source n
