ARC-GYDE™ WIRELESS
STEERING SYSTEMS for HDD APPLICATIONS
|
 |
ARC-GYDE™ IS A FAMILY OF WIRELESS
DIRECTIONAL STREERING SYSTEMS
|
ARC-GYDE™ uses
Boregyde's CABLELESS™ through-the-earth telemetry, that
eliminates
the need for expensive and troublesome wirelines. The "connection"
between
the Down-Hole Sonde and the Surface Subsystem is by Electro-Magnetic
(E-M)
waves. This feature allows a Steering Tool to operate without a
Wireline!
It is comprised of the following:
- A Down-Hole Subsystem consisting of the Instrumentation
Sonde, Drill-String Antenna, and a Non-Magnetic Drill Collar.
- A Surface Subsystem consisting of the
Receiver-Processor, Notebook PC, and Safety Barrier Box.
- Optional items include a Printer-Plotter, Remote
Driller's Display, and other accessories.
- MICROGYDE™ and/or TruTracker®
(to provide enhanced accuracy).
|
ARC-GYDE™ REDUCES COSTS!
|
| The CABLELESS™
feature eliminates all wireline costs. It not only eliminates
acquisition and maintenance
costs, but eliminates lost time due to splicing costs and failed
wireline
repair trips costs. Additional savings result from increased driller
efficiency that is provided with accurate and easily assimilated
graphical presentations of drilling progress relative to the planned
trajectory. ARC-GYDE™ may be operated directly by the
driller from the drilling console. Even
when using TruTracker® or MICRO-GYDE™
manpower is reduced below that normally required because ARC-GYDE™
partially automates these functions. |

- All functions are selected from an easy to use set of
menus.
- PC displays:
- Text and graphical presentations of drill orientation
- Planned and actual position plus steering correction
for optimal return to the planned path.
- All necessary calculations are performed by the computer.
- All raw and calculated data are stored on hard disc.
|
- Operator can choose among several types of displays
while drilling; including:
- Current survey data,
- Historical survey data,
- Planned/Actual trajectory or steering to path.
- Operator can select the current "as-built" showing a
comparison of the actual VS planned trajectories.
- All data can be printed/plotted at the drill site.
|
ARC-GYDE™ IS ADAPTABLE!
|
- ARC-GYDE™ In-hole Antennas are available
in different sizes (OD): 2¾", 3½", 4¾",
6½", 9½", other
- Threads at each end of the Antennas are in common usage
for the comparable survey collar.
- The drilling contractor generally supplies collar as
required to make up a suitable Bottom-Hole-Assembly (BHA).
|
- Sonde Unit is compatible with all of the Antennas.
- ARC-GYDE™ batteries may be recharged
without removing the Sonde from the BHA by simply connecting the
battery charger across the Antenna.
- Alkaline battery sticks are available for longer
downhole runs.

COMPUTER
All ARC-GYDE™ Systems
utilize an
IBM-compatible personal computer to process, store, and provide a
graphic
presentation of the steering, position, and survey information. Users
may
choose to furnish their own computers or may purchase computers from
BoreGyde. |
OPTIONAL EQUIPMENT
DRILLER'S DISPLAY
BoreGyde offers two different auxiliary hand-held Driller's Displays:
1) wire connected and 2) radio linked. Both display graphical and
numerical steering data along with the ability to operate the Surface
System from
remote locations. |
MAGNETIC INFLUENCE
ARC-GYDE™ offers two different
accuracy-augmentation systems for use in scenarios where there are
magnetic field influences that may
cause errors in the Azimuth data. Both systems are semi-automated
within
the ARC-GYDE™ hardware and software.
1) MICROGYDE™ is a proprietary system of
BoreGyde, Inc. and is operated under license from BoreGyde, Inc.
2) TruTracker® is a proprietary system of
Tensor, Inc. Operators must acquire a license from Tensor, Inc. to use
the system.
|
MICROGYDE™
MICROGYDE™ is an auxiliary walk-over system that
determines the track (left/right location in the horizontal plane) and
depth (location in the verical plane) of the Down-Hole Subsystem of ARC-GYDE™
Cableless™ Steering Systems. MICROGYDE™
operates in conjunction with the unique Electro-Magnetic (E-M) field
created by the Down-Hole Subsystem. System accuracy is about 2% of the
borehole depth, at the point of measurement. |
TRUTRACKER®
TruTracker® is a system that operates in
conjunction with a wire loop laid on the ground above the drill path.
The wire loop
is excited with a current that creates a magnetic field measured by the
downhole system to determine the downhole system position. BoreGyde has
integrated the process into the ARC-GYDE™ system. |
