About
Built by oil and gas engineers, not a software shop.
Front End Engineering Consultancy (FEEC) is an independent upstream and midstream engineering consultancy. BarrierLedger is the well integrity product in its software family, built and supported by the same engineers who write the integrity methods it applies. Each operator reviews and adopts a method profile for its own well types before any of its wells is assessed.
Why we built it
Integrity lived in a spreadsheet. The reasoning lived in someone’s head.
Operators managing tens to hundreds of wells usually run well integrity out of a register that has grown over years. It works — until the person who maintains it is on leave, or until someone asks how a status was decided and the answer is a memory.
The enterprise alternative is real software, but it is sized and priced for portfolios an order of magnitude larger, with implementation programmes to match. The gap in the middle is where BarrierLedger sits: the discipline of a proper integrity system, on the registers operators already keep, without a two-year programme.
The engineering position is simple. An integrity status that cannot be explained is not much better than a guess, and an engineering value a vendor invented is worse than one your own policy supplies. So the platform carries your rules, records where they came from, and shows its working.
How we work
Four commitments that shape the product.
The method is written first
The signed method defines the assessment rules and published defaults. Operators supply their governing MAWOP/MAP values, and tenant-policy changes use a versioned request-and-approval path.
A status has to be explainable
If someone asks why a well carries the status it does, the answer should be in the record: the reading, the governing limit and its source, the profile version and the rule that fired.
Acceptance is a reconciliation, not a demo
A pilot is accepted when your own register is reproduced against the acceptance criteria agreed in writing first, signed off by your integrity engineer — not when the screens look convincing.
The operator stays responsible
BarrierLedger provides well-level assessment views and test records. Regulatory submissions, official well records and the decision to declare a well safe remain with the operator.
Engineering services
The platform, and the people who wrote the method.
Services stand on their own. An operator who is not ready to subscribe can still have the register assessed properly, and a pilot is the bridge between the two.
Register health check
A fixed-fee assessment of the register you already keep: data quality, the MAWOP/MAP basis behind it, and where it stands against the method. The usual first step.
Full integrity assessment
A complete assessment across the agreed wells, with acceptance criteria agreed in writing first and a signed-off reconciliation against your own figures.
Method profile development
Turning your integrity policy into a versioned method profile for a well type — including the exception policy and test scheduling. The profile is signed by its method owner before it is used.
Reconciliation and parallel runs
Running the platform alongside your current process and reporting every difference with its reason, so the change is evidenced rather than asserted.
Method profiles you own
