Survey
Enter stations, then compute TVD, N/E, DLS and vertical section.
| # | MD | Inc | Azi | TVD | N | E | DLS | VS |
|---|
No stations yet — add a tie-in at MD 0.
DLS calculator
Build, turn and dogleg severity between two surveys.
Steer to target
Toolface and DLS to reach a target attitude over a course length.
Projection
Project a point ahead, holding angle or steering to a target.
Stuck pipe
Answer three questions, or pick a scenario to see its signature.
Torque calculator
Collar / connection make-up torque — the weaker of pin and box governs.
Pin ID rounds up to the next listed bore; box OD rounds down.
Continuous inputs
Paste a continuous log, one station per line. Per-station DLS and toolface.
Downlink player
Pick a command below, then Start. The app builds the exact HUB flow waveform — steady-flow lead-in, Manchester-coded bits — and cues every change with a 5-second warning.
Command reference
Formation tendency
Build/drop and walk from formation dip for the current hole attitude.
Plan
Solve a build-and-hold (J) or build-hold-drop (S) profile to a target.
Anti-collision
Scan your current survey against an offset well (3-D least distance).
Advisor
Toolface, steer setting and metres to drill from current to target attitude.
BHA tendency
Bit side force and build/drop tendency from stabilizer geometry (beam-column).
Stabilizers — nearest the bit first:
| # | Dist to bit m | Blade OD in |
|---|
Return to plan
Smooth correction from your last survey back onto a loaded plan.
Spacing
Spread a turn over enough stands to keep the surveyed DLS under a cap.
Motor yield
Back-calculate the dogleg your motor/RSS actually delivers at 100% slide.
Slide sheet
Log slide and rotary intervals; footage and slide ratio roll up automatically.
Ranging composite
Shift the sensor-well survey by the ranging result. Enter the signed shifts: N/S (+N −S), E/W (+E −W), TVD (+deeper −shallower). The composite runs from the start MD: zero shift there, growing linearly to the full value at the last survey station (where the shot was taken). Shift is distributed linearly with measured depth (standard practice); positions are definitive. Inc and azi are the corrected path's tangents (shift gradient added to the wellbore tangent).
