OnTrak Rigging/Logging Platforms

OnTrak Rigging/Logging Platforms

OnTrak™ is a platform of on-drill measurement and on-drill logging tools designed to collect real-time downhole data during oil drilling to help optimize borehole trajectory, formation evaluation and drilling efficiency. The platform integrates multiple measurement functions with real-time data transmission as a core benefit for a wide range of applications in directional and horizontal wells and complex formations.
  • dominance:
    • For formation evaluation, natural gamma and resistivity logging are the most basic logging parameters

    What it means to the customer:
    • Measurement and control of borehole trajectories
    • Determination of reservoir hydrocarbon reserves
    • Accurate characterization of reservoir physical parameters accurately assists the client in evaluating their investment
    • Logging with drilling reduces the effects of mud intrusion and is therefore more accurate than conventional cable logging
    • Reduced non-productive time, logging while drilling

    Implications for the Baker Hughes Drilling System:
    • An integral part of an openhole data acquisition system
    • There is no alternative to OnTrak: the downhole LWD toolset “Command”
    • Provides critical measurements for deeper reservoir understanding
    • Tools Self-diagnostic data integrity
specificities:
  • Well inclination and azimuth measurements
  • Rotational azimuth measurements
  • Double gamma/average gamma 8 sector azimuthal gamma imaging
  • Measurement of vibration/stick-slip, bottoming out rotational speed
  • Overall sensor design:
    • High reliability
    • Built-in for all components

    MPR technology:
    • 2 MHz and 400 kHz
    • 4-channel dual-receiver architecture
    • Acquisition of 8-bar compensation resistivity
    • Circumferential pressure (ECD):
      • Optional battery ensures that the pump can be stopped for pressure measurement
  • norm:
    • Temperature = 150oC (175oC optional)
    • Pressure level = 30,000 psi max

    Tools/borehole size:
    • 4 ¾”(5 ¾” – 6 ¾”)
    • 6 ¾”( 8 3/8” – 9 7/8”)
    • 8 ¼” (10 5/8” – 12 ¼”)
    • 9 ½” (12 ¼” – 26”)
