The short answer

  • OEE Lab is a free CMMS and OEE tracker for oil, gas and petrochemical operations. Log every shift, read availability, performance and quality, and open work orders against pumps, compressors and process assets.
  • It runs in your browser with no account, so a control room or maintenance lead can start on one plant and one device today.
  • It stays honest about scope: manual shift logging (about two minutes), one plant per device, and you investigate downtime causes yourself using the built-in Pareto.
  • When continuous uptime, PLC-read OEE and audit-ready evidence across sites matter, Fabrico is the paid upgrade.

In oil, gas and petrochemical plants, a single unplanned stop on a pump, compressor or process train can idle a whole unit, so the value is in catching losses early and closing them fast. OEE Lab gives you a free way to record every shift and understand what OEE is for your assets, tracking availability, performance and quality without a spreadsheet. It pairs a simple OEE tracker with a work order board so a downtime event becomes a fix, not just a note, and the cost of downtime stays visible.

On the maintenance side it works like a light free CMMS: an asset register for your rotating and static equipment, a work order board for corrective jobs, and a preventive maintenance schedule so inspections and lube routes do not slip between turnarounds. Everything is browser-local, so there is nothing to procure and no login to wait on.

Be clear on the trade: logging is manual and lives on one device, so you read the downtime Pareto and chase the true cause yourself. Those limitations are fine for one plant getting started, and when you outgrow them this guide on when to upgrade covers the move to a connected, audit-ready platform.

What you get, free

Two-minute shift logging

At handover, log run time, stops and counts for each unit in about two minutes. No account and no setup, and the entry lives right in your browser so the next shift picks up where you left off.

OEE with A, P and Q

See availability, performance and quality for every asset, with a per-machine breakdown so a lagging compressor or pump stands out against the rest of the train.

Downtime Pareto

Every logged stop rolls into a Pareto chart that ranks your biggest loss reasons. On continuous process units, that is where you find the few causes eating most of your uptime, so you know what to attack first.

Work order board

Turn a stop into a corrective work order and track it from open to done. Assign it to the people and roles held on the device, so a seal leak or valve issue does not get lost between the log and the fix.

PM schedule and asset register

Keep a register of your rotating and static equipment and set preventive schedules for inspections, lube routes and calibration checks, so recurring work is planned around turnarounds instead of forgotten.

Export, backup and reports

Export everything to CSV or JSON, back up and restore your data, and generate a printable PDF report or a shareable scorecard. Useful when a reliability review or safety walk-down needs the numbers on paper, and it supports audit-readiness.

Start in two minutes, no account needed

Log one shift and the free tracker shows your OEE, your loss Pareto and how you compare to world-class. Add work orders and preventive-maintenance reminders in the same place.

Where free stops, and Fabrico begins

The free tracker is built for getting started fast and for one plant on one device. When a site gets serious about its losses, the manual steps start to cost more than they save. This is exactly where Fabrico takes over.

Frequently asked questions

Is OEE Lab really free for oil and gas teams?

Yes. The tracker and light CMMS are free and run in your browser with no account and no card. You can log shifts, track OEE, and manage work orders on one plant without paying anything.

Do I need to install anything or create an account?

No. It runs in the browser and your data stays local on that device. You can add it to your home screen as a PWA for quick access, but there is nothing to procure and no login.

Can it handle continuous process units, not just discrete lines?

Yes. You log run time, stops and counts per asset, so pumps, compressors and process trains all get availability, performance and quality. Big single stops and turnaround work show up in the same downtime Pareto.

Does it support audit-readiness and reliability reviews?

It helps. You can export CSV and JSON, back up your data, and print a PDF report or share a scorecard, which supports audit-readiness and safety walk-downs. It keeps records you control rather than acting as a system of record.

When do I need more than the free tool?

When manual logging on one device is not enough: you want OEE read straight from the PLC, micro-stop causes proven with video evidence, work orders routed automatically, and audit-ready records across several sites. That is where Fabrico fits as the paid upgrade.

How is my data stored and can I move it?

Everything lives in your browser on the device you use. You own it and can export to CSV or JSON, or use backup and restore to move it to another machine. Nothing is uploaded to a shared server by the free tool.

When free is not enough, Fabrico is the upgrade

OEE Lab is deliberately light: it is ideal for getting one plant logging and reading its losses, but you do the capture and the detective work by hand. Fabrico is the paid step up for oil, gas and petrochemical operations that need more. It reads OEE straight from the PLC and closes the loop by auto-routing a work order the moment a loss appears, and its computer vision pins the true cause of micro-stops with video evidence instead of a guess. It is EU-built with EU data residency and certified to ISO 27001, 20000-1 and 9001, so the records behind your reliability and audit reviews hold up.
