BHA sag pre-analysis software description

The quality of survey measurements is effected by several error sources. One of them is the misalignment between the survey tool collar and the borehole axis.

This error is known as BHA sag. This error has a significant impact on the inclination survey, and is responsible for 80% of the TVD uncertainty.

Therefore, the BHA Sag Pre-Analysis module allows quick control of the BHA sag in order to optimize the BHA configuration and survey tool position according to the calculated sag error budget.

Benefits of BHA sag pre-analysis

  • BHA design optimization for sag mitigation

    Check the most suitable position of a sensor package considering the BHA deflection and the expected sag correction.

  • Powerful 3D calculation model

    Our model takes into account the rock/bit/BHA/hole interaction, BHA configuration, well architecture and the operating parameters.

  • All BHA types supported

    The BHA Sag Module computes sag correction for rotary, VGS, motor, RSS, underreamer BHAs and dedicated survey strings.
