OPERATING THE LOGGING SYSTEM
Assuming basic familiarity with SAS 1000 / 4000, these would be the steps to set up for a
well logging
1.
In the Application menu, select SAS LOG 300,
.
2.
In the Record Manager Menu, define a NEW log title,
. (Or OPEN an old file or
DELETE records,
.
)
3.
In the next menu, define the LOGGING INTERVAL in meters. This is the smallest
conceivable distance between two logging points,
OK
4.
In the Log Configure menu, page 1(9), enter the distance steps for downwards and
upwards logging (the logging interval is multiplied by this number, the return is the
actual distance between the logging points in the respective run) and select which
modes should be utilized on the way down and which on the way up, see paragraph
8.2.3,
.
5.
In the SP Parameter menu, page 2(9) select desired SP measuring time,
.
6.
In the Measure Parameter menu, page 3(9), make the desired resistivity settings,
.
7.
In the IP Parameter menu, page 4(9), make the desired IP measuring settings,
.
8.
Calibrate temperature, page 5(9), the log is shipped with default calibration values
entered, which allow the stated accuracy. For special demands other values may be
entered.
9.
In the Stack Parameter menu, page 6(9), enter details for stacking and also whether to
view apparent resistivity or resistance (plain V/I, without geometry calculations),
.
10.
In the Options menu, page 7(9), set options for the current transmitter,
.
11.
In the Info Text menu, page 8(9), make all the comments for the actual survey,
or
.
12.
Return to the View Sample menu, page 9(9), to view retrieved data
.
13.
Select whether to follow the sequences preset in point 4 above, Down,
or, Up,
.
Options are,
/ :
•
Electrode Check, to verify whether the remote electrodes are properly installed,
..
•
Level Check. Select this function and lower the probe, an indication is given on the
SAS 1000/ 4000 LCD when the probe reaches the water level,
.
•
Depolarise, equalizes built up potentials prior to SP measurements,
.
•
Take single readings in any function mode at any arbitrary depth,
.
14. The last retrieved data is shown in the upper part of the LCD, together with the relevant
depth information. The next measurement and the appropriate new level according to the
settings in point 4 above are suggested in the lower half of the LCD.
