22. Save Drill Data Occasionally
DCI recommends that you save the drill data periodically during the bore. A suggestion is to include the
name of the project, the horizontal distance from the launch point (
“Dist.” column in data points table), and
the LWD software version in the filename. For example, for a job where Pole Road is the name of the
project, 880 feet is the x-distance from the launch point, and the LWD software version is 2.04, an
appropriate filename would be “Pole Road 880 v2.04”.
23. Log Last Rod
The last rod logged is just as important as the first. At the end of the run, with the tool at the exit location,
you must measure the length of the last rod and input the length in the Rod Length Information area of
the Steering Tool Data Upload Control dialog box before logging the data point. The last rod
measurement is the rod length minus the length of drill rod left on the rack. For example, if you measure
6 ft (1.8 m) from the make-up/break-out clamps to the top of the rod, then you would subtract 6 ft (1.8 m)
from the rod length. If the rod length is 10 ft (3.0 m), then the last rod measurement will be 4 ft (1.2 m).
NOTE
: If the depth of the last rod is less than 24 in. (61 cm) and you are tracking the SST
transmitter with the receiver, you must set the height-above-ground (HAG)
measurement and log the last data point above the ground level for an accurate
depth reading, or you can record a pitch-only data point.
Last Rod Measurement
Press the Log button after modifying the rod length to the last rod measurement value.
24. Save Project
DCI recommends that you save the project at the end of the bore using at least two different names,
which will provide
an extra copy of the data for backup. Then, if you accidentally make changes you don’t
want, you can still revert to the earlier version of the file. You may even want to save the drill data more
than two times.
