Automation

Our automatic MWD survey processing workflow provides complete autonomy of work under normal conditions. It covers all the stages: geomagnetic reference calculation, survey data prefiltration, MSA correction, BHA sag correction, compensation for the trajectory interpolation error, system health assessment, survey QC, and accuracy analysis.

The four cornerstones ensure the highest system reliability:

  • Initialization validation
  • Input data filtering
  • Key algorithms robustness
  • Continuous QC

The system shows complete stability to the noisy data input: static surveys, continuous inclinations, and slide sheets. It works without the no-go zone restriction, corrects the directional surveys within high calibration and DSI error ranges, effectively detects  geomagnetic reference errors and system malfunctions, provides realistic recommendations on toolcode. The system significantly reduces human errors and engagement in real-time survey processing1.
