Predict coupled bit/BHA directional behaviour before the run

Evaluate and mitigate the BHA’s disposition to create detrimental borehole oscillations

Identify and avoid sensitivity to multiple operating parameters by optimizing BHA design and drill bit selection

Determine unknown reasons for counter performance in a post-mortem process

Wellbore trajectory prediction service description

The Wellbore Trajectory Prediction Service enables evaluation of any BHA design propensity to create detrimental borehole oscillations, such as hole spiraling.

Accounting for all information about geology (UCS log, Dip and Strike) and planned drilling parameters, we are able to anticipate potential inabilities to meet your directional objectives and expectable local tortuosity of a wellbore from a drill ahead mode with varying local conditions.

This analysis provides step-by-step projection of what can happen in the field and allows to assess the sensitivity of any type of BHA (Rotary, VGS, Motor, RSS, URWD…) to multiple operating parameters such as WOB, Hole Overgauge, Activation level, Toolface, Bit Walk and Steerability,…

By comparing the predicted behavior of the BHA to the planned objectives, we provide recommendations to optimize the Bit-BHA design and we help you to implement the most adapted mitigation measures to increase your drilling performance.

The Trajectory Prediction Service is a powerful Pre-Engineering tool that can also be exploited into a Post-Mortem process to determine unknown drilling parameters reasons for counter performance and improve the Bit-BHA design and behavior for next runs within a given environment.

Benefits of wellbore trajectory prediction

Service usage by project phase
Pre-WellReal TimePost-Well
  • Drilling Performance

    Implement the most cost efficient mitigation measures to increase your drilling performance.

  • Hole spiraling

    Reduce NPT and hidden lost time by avoiding effects of hole spiralling and increased friction

  • Casing hole completion

    Reduce borehole tortuosity to ease RIH operations hole for future casing or completion operations

  • Landing strategy

    Reduce uncertainty on drill-ahead and landing strategy (e.g. in complex geology)
