PARATRACK-2 AC BEACON
The AC Beacon is one of the several available magnetic field sources used by the ParaTrack-2 system. The AC Beacon is superior to the conventional wire coil since it may be oriented quite precisely to optimize the magnetic field vectors at the receiving unit, usually the ParaTrack-2 Guidance Probe, thus producing an accurate and reliable drill bit location.
The AC Beacon Advantage
The AC Beacon IS:
- Used without a surface guide wire
- Used to compliment existing guidance methods
- Used to give guidance information up to 130 meters offshore when installed at the edge of a water source
- Installed inside buildings while drilling underneath
The AC Beacon HAS:
- Assisted the establishment of the initial line azimuth for drilling away from the entry guide wire.
- Positively guided large 110 degree curves.
- Positively guided entire crossings without use of a surface cable.
- Benchmarked crossings under golf courses.
- Determined drilling positions under buildings and in harbors.
OPERATIONAL CHARACTERISTICS...
The AC Beacon consists of two wire wound steel core solenoids Mounted on a table of two degrees of freedom. The table doubles as a transport case holding the electronics, table legs and controls. A 12 VDC deep discharge battery can handle an all day Operation with recharge in the Evenings.
The AC Beacon is deployed on or offset to the centerline. It is oriented to a known azimuth, normally the line azimuth, and leveled using the provided bubble levels. Remote actuation of the AC Beacon is accomplished from the laptop keyboard by clicking a button on the software screen causing a tone to be generated through the radio at the AC Beacon location.
After actuation, data is saved on the main ParaTrack 2 screen and the tracking algorithm is used to determine elevation, left/right position and the confirmed away-distance from entry.
TRACK RECORD
To date, the AC Beacon has been used more than 100 meters offshore where conventional coil layout is impossible.
The AC Beacon has been deployed on golf courses where unsightly surface cables were prohibited.
It has been used to locate a drilling path accurately before crossing the exit side coastline to ensure accuracy and to limit the real possibility of damage.
Outfalls are a major planned use of the AC Beacon where surface wires are difficult to install in the surf zone and inaccurate where unseen.
In conjunction with other tracking methods, The AC Beacon assists long reach intercept drilling by ensuring the two approaching bores are within tolerance of each other in order avoid pullbacks.
