Built for wireline and production logging crews

From LAS Files to
Finished GLV Survey.

FloTrace reads the passes off your logging tool and builds the survey. It picks up the curves, calibrates the spinner from your calibration passes, calls each valve open or closed, works the rates out in Mscf/D, and lays out the log presentation, gradient plots and summary tables.

The write-up comes with it. You check it, put your name on it, and send it.

No re-typing depths into a spreadsheet. No rebuilding the same chart for the hundredth time.

What it does with your files

  1. 1

    You drop in the files

    Any LAS, whoever the tool came from

    Down passes, up passes, stationary stops, surface recorders, ASCII gauge exports. Curves are recognised on arrival — DEPT, CCL, CFM, ILS, PRES, TEMP, ADEN, GR — whatever the tool called them, and whatever order they came in.

  2. 2

    The spinner gets calibrated

    The step almost nobody does

    Most interpretation normalises: fastest zone is 100%, everything else a share of it. FloTrace fits the calibration passes your crew already shoots — rps against cable speed — and solves the tool constant and the bearing-friction threshold. That is the difference between a percentage and a rate.

  3. 3

    Valves get called

    Open, closed, or honestly unresolved

    Every mandrel kicks the spinner whether or not the valve is passing gas. What decides it is whether the trend returns afterwards or settles on a new one. And where the flowmeter sat inside its own deadband, the valve is reported unresolved rather than guessed — which tells you what the next run needs to carry.

  4. 4

    Rates come out in Mscf/D

    Not "this one is 100% and that one is 40%"

    Each zone converts at its own pressure and temperature, so a deep valve yields far more surface gas per downhole cubic foot than a shallow one. On a well we tested, the calibrated total landed within 0.4% of the casing meter — from the tool’s own passes, nothing scaled to match.

  5. 5

    The report comes out

    Including the write-up

    Log presentation, gradient plots, valve summary, zone contributions, ops log, well diagram — and the introduction, observations and interpretation, drafted from the computed table and never from figures it was not given. Your analyst edits and signs it before anything leaves.

Every survey on your menu

The report is chosen from what the file actually carries — a caliper log produces a casing inspection, a log with QWZI and QWZT produces an injection profile, a flowmeter and valve depths produce a GLV survey.

  • GLV optimisation / flowing gradient
  • Bottom hole pressure & temperature
  • Injection profiles — spinner or tracer
  • Step rate & injectivity tests
  • Multi-finger caliper / casing inspection
  • Dip-in pressure–temperature surveys

Your name on every page

White label throughout — your logo, your colours, your disclaimer. The operator sees your report. They never see us.

One workflow, start to finish

Files land, curves are read, rates are computed and the PDF goes out — without exporting into a second package and back. The delivered file is archived against the job, so an interpretation questioned six months later can be reproduced exactly as it was sent.

It tells you when it cannot tell

A valve the flowmeter could not resolve, a calibration shot in moving fluid, a downhole total that disagrees with the allocated surface split — all said out loud. A number quoted with false confidence is the one that costs you a customer.

Request access

There is no sign-up button on purpose. Workspaces are opened by hand, and we would rather work one of your own surveys first — ideally one where you already know the answer, so you can see where we agree with you and where we do not.

Accounts are set up by hand — we’ll want to see one of your jobs first.
