Designed and Manufactured by American Augers, Inc.
American Directional Drill utilizing American Augers more than 37 yearsof horizontal directional drilling and underground technology experiencehas revolutionized oil and gas drilling with the introduction of the VR-500.With 500,000 lbs of thrust and pullback force, standard three unit system,and innovative operations, the VR-500 will impress drill operators with anemphasis on Speed, Performance, and Safety!
SpeedThe VR-500 provides optimum bit load from initial surface contactthroughout the entire drilling operation. Operators also have the ability toimmediately start a horizontal curve after surface penetration resulting ingreater access to shallow formations. American Augers designed the VR-500on the premise that Greater Penetration Rates = Greater Profi ts.
PerformanceThe VR-500 showcases American Directional Drills commitment toproviding equipment with maximum Push/Pull Thrust and Rotary Torquefor increased working power and reserve capacity. The Best-In-IndustryTop Head Drive equipped with Slip Spindle is rugged and durable yet easyon Pipe Threads. The remote operated Pipe Handling System ensuresControl/Ease/Safety of the Loading Operation.
SafetyThe VR-500 eliminates many traditionaldrilling components, such as cables, tongs,and catheads, which reduces injuries anddowntime. Standard OperatingProcedures limits the need forcrew members to be on thedrilling fl oor, which contributesto improved jobsite safety.

EXCEPTIONAL FORCE
One major advantage of the new American Directional Drill VR drilling system is that it can operate at extremely shallow depths (like zone 1 in the graphic) since the VR uses rack and pinion thrust, rather than gravity, to load the drill bit. No pay zone is off limits because of being too shallow.

This graphic shows how directional drilling (on the left) for energy will expose more feet of casing to the pay zone, when compared with straight vertical drilling (on the right). The zoom shows detail of a “frac” to open up the formation so it can exhale gas into the casing.

EXCEPTIONAL FORCE
Did You Know: American Augers was the fi rst directional drill manufacturer to eliminate chain and utilize a rack and pinion carriage design, which is now the industry standard. The American Augers rack and pinion driveprovides smoother carriage movement, more precise operating control, longer system life, with less wear, and there are no complicated parts, that need to be consistently replaced. Innovations like these have allowed AmericanAugers customers to perform at their best in all forms of utility installation and underground application projects.

Technology Spotlight:
Wiggle Steer
WiggleSteer
Sensors
Provides the operator of a Directional Drill the means to rotate the drill pipe and subsequently the cutting head on the drill string back and forth over a predetermined range.
This back and forth motion would cause the hole made by the cutting head to be more open in a particular direction and therefore facilitate steering of the drilling pipe in that direction under ground.
The Wiggle Steer System will rotate the Drill Pipe in the Makeup (CW) direction while thrusting forward. It will then rotate the Drill Pipe in the Breakout (CCW) direction but will not thrust in thebreakout direction. This method reduces the breakout torque and should prevent the drill string tool joints from parting down-hole.
The Wiggle Steer System counts pulses from the RPM Sensors on the RPM Gear that are compiled in the RPM meter. The Meter then sends a signal to the Carriage/Rotary Joystick(s) to control direction of both the Carriage and Rotary circuits. The speed of the Wiggle SteerRotation and Thrust are controlled by the Carriage/Rotary Joystick(s).
