DLS calculator

Build, turn and dogleg severity between two surveys.

Norm length m

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.

Pull last survey station Course ΔMD m

Torque calculator

Collar / connection make-up torque — the weaker of pin and box governs.

Connection Make-up factor

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.

Rows — “depth inc azi”, or template “depth mwdInc mwdAz pdInc pdAz”

Downlink

Pick a steering page and command to see its flow pulse pattern.

Steering page Filter

Formation tendency

Build/drop and walk from formation dip for the current hole attitude.

Up-dip/down-dip crossover °

Plan

Solve a build-and-hold (J) or build-hold-drop (S) profile to a target.

Profile Build & hold (J) Build-hold-drop (S) Azimuth °

Anti-collision

Scan your current survey against an offset well (3-D least distance).

Offset well survey — “md inc azi” per line

Advisor

Toolface, page 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:

Steerability °/30m per kN

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.
