Mechanical String Model
Torque & drag model for drilling & completion operations
- Standard soft string model with extensions
- Buckling and post-buckling calculations
- Torque-buckling interaction
- Wall climbing effects
- Tri-axial stress calculations including the effects of hydraulic pressures and buckling
- String length correction due to axial loads, buckling contraction, thermal expansion and hydraulic pressures
- Flow-induced forces
Wellbore trajectory interpolation using Minimum Curvature Method.
- Effects of cuttings accumulations
- Tight spots
- Stuck pipe
- Realistic feedback on WOB and ROP
