    The dynamics of drilling high-angle and extended reach wells

    • Advanced
    • 4 Days
    • Remote Instructor Led SeriesRemote Instructor Led Series

    Participants in this case will gain anunderstanding of the nature of transient and dynamic processes in the drillingsystem, especially those in high-angle and extended reach wells.  They will gain knowledge to better interpretthe behavior observed while drilling wells, enabling a more informed choice ofdrilling components and parameters to drill wells.   Much of the course content is based on theinstructor’s own work at a Schlumberger research centre.

    Day 1: Introduction

    ·       Long and short timescaleeffects

    ·       Different modes ofdynamic behaviour

    Day 1-2 : Rotational and fluid dynamics

    ·       Rotationalself-excitation, starting and ceasing rotation

    ·       Stick-slip phenomena

    ·       Fluid dynamics - pumpstarts and flow changes

    ·       Dynamics of drilling withpositive displacement motors

    Day 3: Autodrillers

    ·       Drilling under weightcontrol

    ·       Drilling under pressurecontrol

    Day 3-4: Lateral buckling

    ·       Critical buckling loadvariation with hole angle and hole size

    ·       Buckling transitions

    ·       Propagation ofdisplacement through touch points


    Day 4: Lateral dynamics

    ·       The dynamics ofcylindrical pipe in high angle wells

    ·       The dynamics of drillpipe in high angle wells


    Drilling Engineers, Well Drilling engineers, Drilling and Completion superintendents, Drilling supervisors and other personnel that are involved in the planning and drilling of high-angle and extended reach wells.

    • The dynamics modes of the drilling system
    • Axial dynamics of drilling; The drill-off time as the characteristic time constant of the system
    • Rotational dynamics; The drillstring can be self-excited in rotation, leading to persistent rotational oscillations at a range of frequencies.  
    • Fluid dynamics;  The fluid behaviour as a damped, compliant system with a long characteristic time.  
    • Positive displacement motors; Motors couple axial, rotational and axial modes, and affect the dynamics in many interacting and unexpected ways.  The difference in dynamics between oil and water based drilling fluid
    • Autodriller dynamics; Autodriller parameters govern the dynamics and stability of the axial system, with large differences between drilling under weight and pressure control
    • Lateral buckling; The combination of axial compression, gravity and borehole contact generates a variety of buckling and bending phenomena which will be described.
    • Lateral dynamics; The lateral dynamics of collars and drillpipe are strongly affected by compression and borehole contact, leading to different types of behaviour in different frequency ranges.
