PDC bit model software description

Multiple PhD theses are at the origin of the PDC Bit Model. Extensive expertise and diverse bench & field tests have validated the model. Sensitive to rock hardness (UCS) and friction factor, the PDC Bit Model is very detailed.

Our model is based on extensive experimental validation conducted at the MINES ParisTech facilities in Pau (France).

This module helps in the bit choice, a key factor in the directional response of any drilling system. It evaluates the steerability and walking tendency of any PDC bit which are the parameters commonly used by the bit manufacturers. Using BHA Management modules (such as BHA Pre-Analysis and BHA Post-Analysis modules) coupled with the PDC Bit Model module will enhance simulation accuracy.

Benefits of PDC bit model

  • Extensive scientific background and field validation

    The module was based on multiple PhD thesis. Extensive expertise, bench and field tests validated the theoretical models, in collaboration with major Operators.

  • Choose the best bit depending on BHA objectives and design

    PDC bit design has a crucial impact on the directional behaviour of a BHA. The module PDC Bit Model helps you to optimize the directional response of any type of BHA (Push-the-Bit or Point-the-Bit RSS, Rotary BHA, Steerable Motor BHA, Pendulum…).

  • Formation sensitive

    The module PDC Bit Model computes the steerability and walking tendency of a PDC bit in different formations and rock hardness.

  • User oriented interface

    The module interface is easy to use and understand. It helps the drilling engineer and the bit manufacturer both have a clear and simple exchange to rapidly identify the optimum bit features requested for a given directional application.
