Receiver Screen Tracking "On-the-Fly"
Actual Position of
Receiver and Transmitter
As the tool advances, the FLP should travel along the receiver’s vertical crosshairs indicating that the tool
is still on line. Once the FLP is in the box, hold the trigger in and confirm that the predicted depth reading
is as expected.
Off-Track Locating
The off-track locating technique is useful when it is not possible to walk above the transmitter due to a
surface obstruction or interference. Using the locate line’s perpendicular relationship to the transmitter, it
is possible to track the transmitter’s heading and also to determine if it is maintaining its intended depth.
The off-track locating method is only effective when the pitch of the transmitter is 0% (0°) and traveling
under flat ground.
To explain how the off-track locating method works, we will use the example of an obstruction that is on
the intended bore path, as shown in the figure below. The transmitter is about to go under the obstruction.
1. Stop drilling and find the LL of the transmitter by putting the line in the box.
2. While holding the trigger in and keeping the receiver in the same orientation, step to the side of the
tool until you reach a predetermined distance (P1) from it. Move the receiver forward and aft until you
can see the ball jump from the bottom of the screen to the top of the screen (or vice versa), then mark
this location.
