Well integrity status, tests and annulus pressures that stand up to audit and review.

For operators who manage well integrity in spreadsheets. We assess your register against a written method, show you exactly where your status and MAWOP differ, and leave you with something an auditor can follow.

The problem

The barrier register is usually one person and one spreadsheet.

  • Status nobody can defend.

    The register says green because that is what it said last month. When someone asks why, the reasoning is in someone’s head.

  • Annulus pressure compared by eye.

    Readings arrive weekly and are checked against a MAWOP figure that lives in a different file — if it exists at all.

  • Overdue tests found late.

    Evidence sits in an email folder, and the first time anyone notices an overdue test is in a review.

How it works

One method, applied to your own data.

  1. Step 1

    Send us the register

    Your spreadsheet as it is, plus the policy or study your MAWOP comes from.

  2. Step 2

    We map and validate it

    Column mapping, per-row validation, and a reconciliation of every status and MAWOP we can check against your own figures.

  3. Step 3

    The assessment runs

    Every well and annulus classified against the written method profile for the engagement, with trends, bands and the flags that matter.

  4. Step 4

    You get the result

    An assessed register, a per-well status report and the reconciliation, with the reasoning and the inputs behind each status.

The deliverable

Not a dashboard demo — a defensible record.

  • An assessed register you can reconcile line by line against your own.

  • Per-well status reports with the barrier schematic, the annulus table and the test history.

  • A reconciliation note that names every difference and why it exists.

  • A data-quality list of what is missing, stale or assumed in your register — usually the most useful page in the pack.

FAQ

Questions we get asked first.

“Excel works.”

It does — until the person who maintains it is away, or someone asks how a status was decided. We are not replacing your spreadsheet as a data store first; we are replacing the reasoning that is missing from it.

“Our wells are unusual.”

The method is written down, versioned and signed before anything is assessed. If your wells need different rules, that is a method conversation, not a code change.

“Is our data safe?”

Real data goes only onto a dedicated host, never a shared one; DPA before anything is shared; full export and deletion on request.

“What about regulators?”

We do not produce regulatory submissions. We give you the record you prepare them from.

Start with one well, or five.

Send us a register and the MAWOP basis behind it. We will tell you what we can assess, what we cannot, and what is missing — before you commit to anything.
