Sag Management is an advanced module of the BHA Management® software platform that allows assessment of BHA sag correction, and related residual sag error.

Sag Correction

The software computes vertical and lateral sag at each survey station.



Residual Sag error

In addition to sag correction, the software allow for the computing of residual vertical & lateral sag error at each survey station. It is a unique methodology developed by DrillScan & TOTAL.



Methodology features

This new methodology is based on:

  • Hole overgauge
  • Mud weight
  • VGS, SM & RSS settings while surveying
  • Wellbore geometry
  • Sensor position


Survey management

This methodology results in:

  • Production of a new survey file
  • New wellbore placement
  • New wellbore ellipsoids of uncertainty
