Ultimate QC receives your rig's surveys over standard WITSML and verifies every station the moment it lands — distance off plan, build and turn rates, field QC gates, anti-collision separation. Live, in the browser, while the well is still being drilled.
The sag check is free and needs no account: type or upload your BHA tally, get the stiff-string FE inclination correction in seconds. Ten free engineering calculators — from TFA & jets to casing burst, MAASP and cement volumes. Learn the theory: anti-collision and BHA sag, both explained with the formulas.
Plan vs actual as it happens: distance off plan at every station, the at-bit trend between stations, and the dogleg that steers you back — before the next connection.
Gravity, magnetic field and dip gates on the raw sensors, plus two independent calculation engines cross-checking every position. A bad station is held and shown, never buried.
Separation factor against offset wells, recomputed per station, with a plain-words stop / build / turn advisory when the picture tightens.
The full evidence-graded survey audit report — the one you attach to the end-of-well package — one click from the live well, built from the data as received.
Connecting is boring, on purpose. Whatever already collects your rig data — Kongsberg SiteCom, Petrolink, Pason, a rig EDR — can push standard WITSML 1.4.1.1 to us, or we pull from your existing WITSML server. Wells, sidetracks and multilaterals land in the right place; positions are refused, not guessed, when the reference frame is unclear. Read the connection guide →
