Tubular string mechanical integrity service description

Drillstring mechanics is a complex domain, where multiple inputs must be taken into account. Using a unique Stiff String model, our Tubular String Mechanical Integrity service determine loads and stresses applied to specific points of a drill string.

Calculated stresses can then be compared to strength and manufacturer specifications to check if the equipment fits with the application.

This process has significant added values in pre-engineering stage, in order to avoid drilling failures. It also can point-out equipment-specific issues after any type of counter-performance.

  • Reduce NPT and CAPEX

    Reduce NPT and CAPEX by avoiding critical string component failure.

  • Reduce hidden lost time

    Reduce hidden lost time in challenging well trajectories (Short/medium radius, 3D complex wells, side tracks).

  • Sensitive downhole tools

    RIH sensitive downhole tools in a safe and efficient manner.

  • Improve learning curve

    Improve learning curve by proper understanding of component failure in a post-well analysis.
