The ROP Optimizer integrates a predictive vibration model with its internal algorithm. This model calculates the resonance rotary speed needed to avoid axial (purple curve), torsional (orange curve) and lateral (red curve) vibrations at any given depth. In this illustration, the range of speed recommendations for a test well is indicated by the green boxes. The actual speeds in the test well are indicated by green dots. Source: IADC/SPE 230787.
