Real-Time Torque, Drag & Hydraulics
In one sentence
Compares what the string should weigh and how hard the pumps should work against what is actually measured, and flags the gap.
The problem
Torque-and-drag modelling is usually done in the office, once, on planned geometry. The rig then drills a hole that is not the planned geometry.
Without a live comparison, a friction factor drifting from 0.25 to 0.40 over a section goes unnoticed until the string will not run to bottom.
How it works
A soft-string model with an optional stiff-string correction is run continuously against the surveyed trajectory, back-calculating the friction factor from every pick-up, slack-off and rotate-off-bottom measurement. Hydraulics runs the same way: predicted standpipe pressure and ECD versus measured, with the residual attributed to cuttings load, bit nozzle wear or a washout.
Everything is physics-based and auditable. There is no learned component in the core calculation, which is why it is classed foundational.
Data required
- Directional surveys as drilled
- String and BHA tally with dimensions and weights
- Hookload and torque with a reliable zero reference
- Mud rheology, flow rate, standpipe pressure, bit nozzle configuration
What you get
- Live friction factor trend by section, with drilling, tripping and rotating cases separated
- Broomstick plot updated per survey and a torque limit projection to section TD
- ECD profile and equivalent static density along the annulus
What it cannot do
Soft-string modelling underestimates torque in high-dogleg and in stiff-BHA cases; the stiff-string correction narrows but does not close that gap. Surface torque measurement quality on older top drives is often poor enough to dominate the error budget, and we calibrate against the rig’s own instrument before quoting any accuracy.
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.

Permeability from Mud Loss Data
Mud that disappears into the formation is telling you something about how easily fluid moves through the rock. This reads that signal instead of discarding it.

Warns that the string is becoming hard to move, typically twenty to sixty minutes before it stops moving at all.
