Polycrystalline diamond compact (PDC) bits with multiple fixed cutters drill through deep formations and are used in oil and gas, geothermal, and mining industry. The bit-rock interaction excites drill string vibrations, which need to be mitigated to

The push in the drilling industry for drilling longer wells, and faster and more difficult trajectories leads to increasing challenges with the dynamics of the drilling systems in particular in expensive high end offshore wells. Dynamic effects are m

Different vibration phenomena and vibration dysfunctions are excited by the drilling process. The associated dynamic loads result in downhole tool failures and inefficient drilling if not properly managed. Vibration mitigation strategies based on adj

High Frequency Torsional Oscillations (HFTO) generate high torsional loads in the BHA causing cracks, damaged electronics or twist-offs. A new Torsional Vibration Isolator tool (TVI) protects the BHA by restricting vibrations to the tools between bit

Vibrations impact the drilling process by reducing reliability, increasing maintenance costs and reducing rate of penetration and drilling efficiency. Herein, torsional vibrations are typically distinguished into low-frequency torsional oscillations

The drilling process is impacted by vibrations through limited drilling efficiency and rate of penetration, reduced reliability and increased non-productive time. The understanding of the mechanisms and physics that lead to high levels of vibrations

Self-excited torsional vibrations of the bottomhole assembly (BHA) at frequencies above 50 Hz, so-called "high-frequency torsional oscillations" (HFTO), can damage drilling tools and can increase non-productive time (NPT). A recently developed HFTO-i

Mechanical loads in hole-opening BHAs result in tool failures and generate maintenance costs and non-productive time. This paper presents a method to increase the reliability of hole-opening BHAs by optimally matching the bit and reamer. The weight a

Oil service companies use highly complex drill string models to optimize drilling assemblies and to perform post-drilling analysis. These drill string models are usually non-linear, FEM based and able to describe arbitrary curved well bore geometries
