Real-Time ROP Optimization
Rate of penetration is how fast the bit makes hole. This recommends the weight and rotation speed that make it fastest without wrecking the bit.

Bit Wear & Remaining Useful Life
In one sentence
Estimates how much drilling the bit has left, so the trip happens on purpose rather than after a failure.
The problem
Bits are tripped either too early, throwing away useful footage, or too late, which risks leaving cones or cutters in the hole and turns a planned trip into a fishing job.
The decision is usually made on ROP decline alone, which conflates bit wear with formation change.
How it works
Cumulative work on the bit is integrated from WOB, RPM and confined rock strength, and combined with the MSE trend and downhole vibration severity. A survival model trained on the operator’s dull-grading history maps accumulated work to expected remaining footage per formation.
Formation change is separated from wear by tracking the MSE-to-rock-strength ratio rather than raw ROP.
Data required
- Time-based WOB, RPM, torque, ROP, and downhole vibration if available
- Bit records with IADC dull grades from the field
- Confined compressive strength estimated from offset sonic logs
- Formation tops and lithology
What you get
- Remaining-footage estimate with an uncertainty band, updated per stand
- Trip-now versus continue recommendation with cost comparison
- Field-wide bit performance league table by supplier and type
What it cannot do
Prediction quality depends on dull-grading discipline, and dull grades in most archives are recorded inconsistently between crews. For PDC bits in abrasive sandstone the estimate is usable; for roller cone bearing failure, which is the failure mode that actually causes fishing jobs, there is almost no surface signature and we do not claim to predict it.
Every capability page states a real limitation. If a vendor cannot tell you where their product stops, you are not being told the truth about where it starts.
