Real-time drilling monitoring system for measuring critical values

The SG-SMART data-acquisition system is an advanced driller’s monitoring system that can accurately measure, monitor, and display all drilling variables in real time. This computer-controlled data-acquisition system employs integrated micro-controller technology and fiber optics to provide accurate, instantaneous  measurement and display critical drilling data.

The patented SG-SMART data-acquisition system provides  intrinsically safe operation in hazardous locations. The SG-SMART,  available  in the basic Level I or more advanced Level II versions, is practical and easy to use.  The modular features of SG-SMART make it expandable for future technologies.

The M-I SWACO SG-SMART measures a host of critical variables for real-time display, including:

  • Mud Pit level
  • Trip Tank level
  • Skim Tank level
  • Analog Spare
  • Return Flow
  • Hookload
  • Pump Pressure
  • Casing Pressure
  • Rotary Torque
  • Methane Gas
  • CO2, H2S
  • Mud weight In/Out
  • Mud Temperature In/Out
  • Mud Conductivity In/Out
  • Depth
  • Downtime Switch
  • Rotary RPM

The SG-SMART Level I provides basic monitoring and measurement functions of PVT (up to 10 pits), gain or loss, PVT for two trip tanks with gain/loss, total pump strokes (5 pumps), return-flow rate (0 to 100%), fill-stroke count (each fill and total).

The Level II system monitors and tracks additional information, including ROP, RPM, pump pressure, hydraulic and rotary torque, weight-on-bit, and hook load.
