configuration and operation of a particular tool type and describes the data
produced from the tool. A copy of the TOL file is placed in the RD file
every time you commence data acquisition with the logging system. If the
TOL file is found WellCAD may prompt you with the option to use this
file or to use an external file (if for instance, the original calibrations are
wrong). This prompt will only occur if the Always use internal TOL file
option is not checked in the ALT Logger default settings dialogue box (see
below). If WellCAD cannot find the TOL file or the named external file
then a default one will be assumed. The minimum information required
from the TOL file includes the name of the tool driver. The default driver
name is given in the ALT Logger default settings dialogue box.
For further information concerning tool drivers refer to the ALT Logger operations
manual. According to the selected driver, various other options will be prompted at
import time. For example if the ABI40 driver has been selected you will have the
options to orient the raw data at import time to either magnetic north or the
borehole high side. Different data subsets can be loaded like 1 st and/or 2 nd echo
images, thickness images, Full Waveform traces, deviation and temperature as well
as various slow channels.
