1. Acoustic System (CEA)
Hardwire System (CE1)

2.  This system has been phased out of use
 CEA system is the original drilling system that was
designed back in the 70’s
 The basic components of the drilling instrument
 Control and Communication package
 Orientation Sensor
 Gamma Sensor
 Battery Pack
 The form of communication that this instrument uses
is acoustic signaling
 Uses a hammer solenoid to pulse and data bit stream
back the drill string
 There is a listener that picks up the acoustic pluses and
turns it back into an electric signal that the Read Out Box
can interpret
 This system is more rugged but is slower and is
susceptible to external noise interference

4.  CE1 system was designed in house and uses
new technology
 The basic components of the drilling instrument
 Control and Communication package
 Orientation Sensor
 Battery Pack
 The form of communication that this instrument
uses is electrical FSK signal
 There is a built in conductor in the drill rods that the
electrical signal travels
 This form of communication is faster and is not affected
by external noise interference
 Though this system is faster it does require more
care and maintenance

6.  Provide Orientation Information
 Roll, Pitch, Azimuth
 Provide the Proximity to roof and floor
 Gamma Sensor detects the natural radiation
of the shale formation
 Provide Horizontal & Vertical Deviation
 The Read Out Box takes the pitch and
azimuth along with the footage that is
provided by the driller to calculate the
deviations

8.  Instrument improvements
 Included gamma sensor to assist with the drilling
process
 Switched housing materials to improve accuracy,
reliability, and longevity
 Redesigned pipe to instrument adapter to increase
water flow and structural integrity
 Made the electronics tray one piece improving
reliability and serviceability
 Made several improvements in the electronics
design and programing to make it more
dependable and accurate

9.  Water Swivel Improvements
 Designed a completely new water swivel
and signal cable
 With this design we have reduced costs and
increased water flow and production
 This new design includes a magnetic
connection between the cable and swivel
preventing a potential hazard to drillers and
damage to equipment
 The in-house design also reduces down
time

10.  Read Out Box Improvements
 Redesign of the Interface board has made it
more reliable and easier to service
 Several improvements in the program have
made it more user friendly and less likely for
problems
 External battery/power supply will reduce
cost and down time (pending MSHA
approval)
