APS’s WellDrill™ software package provides valuable analytical tools for downhole drilling equipment. Data from standard run sheets provide the necessary input. Output data are presented graphically for ease of interpretation. A comprehensive analysis can be completed within minutes.
APPLICATIONS
- Designing downhole equipment
- Establishing tool build rate limits
- Analyzing failures
The complete WellDrill package includes the following modules:
- BHABend™ – Bottom Hole Assembly (“BHA”) bending analysis giving deflections, side loads, bending moments and nominal stress
- BHAVib™ – BHA critical speed analysis
- BHAPredict™ – Predicts the drill ahead drilling tendency of the BHA
BHABend
- Calculates side forces and contact points based on the inclination, weight on bit and build rate
- Predicts buckling within the borehole
- Provides required input data for BHAVib & BHAPredict analyses
BHAVib
- Predicts lateral, axial and torsional critical drilling speeds, enabling reduced vibration damage while increasing ROP
- Displays the deflected mode shapes and natural frequencies
- Predicts drill string response to excitation forces developed by the bit, mud motors and drill string rotation
BHAPredict
- Predicts 3-D drilling tendencies for various types of drilling, including standard rotary drilling, directional drilling with motors and rotary steerable tools
- Calculates the difference between inclinations and azimuth at the bit, compared to what the MWD sensor sees at a given distance from the bit
- Includes effect on drilling tendencies due to formation dip angle
