Annulus pressure monitoring for well integrity engineers
Record tubing and annulus pressures per bore, see them checked against MAASP/MOASP limits automatically, and spot abnormal trends early — so surveillance stays actionable instead of buried in spreadsheets.
Annulus pressure surveillance that supports decisions
Well Integrity Ops helps engineering teams capture readings, review trends, and connect exceptions to integrity context and follow-up actions.
Tubing and A–D annuli per bore
Log annulus pressure tests per bore with tubing pressure and pressures for annuli A through D in one structured record.
Limits shown with every reading
Maximum allowed pressures from the well integrity record appear next to each reading, so out-of-limit values are visible the moment they are entered.
Trend visibility
Filter by pad, well, bore, and date range to spot rising or unstable annulus pressure patterns before they become last-minute review findings.
Linked integrity context
Pressure exceptions sit beside well integrity status, operator notes, and planned actions — no cross-referencing between systems.
Missing readings flagged
WIDR diagnostics highlight wells missing recent annulus readings, so surveillance gaps are caught before they matter.
Traceable history
Every reading and every change is recorded in the audit log — what was measured, when it changed, and who changed it.
Why annulus pressure monitoring matters
The annular spaces between casing strings and tubing are where barrier problems first show themselves. Sustained casing pressure, a slow build in the B annulus, or a reading that creeps toward its limit can each signal a compromised barrier — but only if someone is looking at current data with the right limits beside it.
In practice, that is where spreadsheet-based surveillance breaks down: readings live in one file, MAASP and MOASP limits in another, and the well's integrity status and recent notes somewhere else. By the time the picture is assembled for a weekly review, it is already out of date.
Well Integrity Ops keeps annulus pressure surveillance in the same system as limits, integrity status, notes, and diagnostics, so a pressure move can be judged in context — expected, anomalous, or requiring action — while it is still fresh.
What you can do with it
- Record and review annulus pressures by bore, filtered by pad, well, or date range
- See readings compared against MAASP and MOASP limits automatically
- Attach operator notes and planned actions to the wells that need follow-up
- Feed WIDR diagnostics and integrity reports from the same data
- Export any filtered view to Excel or PDF, or share it as a link
Annulus pressure monitoring FAQ
What is annulus pressure monitoring?
It is the routine surveillance of pressures in the annular spaces of a well — the gaps between casing strings and tubing, usually labelled A, B, C, and D. Sustained or rising annulus pressure can indicate a leaking barrier, so readings are recorded regularly and compared against operating limits such as MAASP and MOASP.
Which annuli can be recorded?
Each pressure test records tubing pressure plus pressures for annuli A through D per bore. The system shows the maximum allowed pressures from the well integrity record alongside each reading, so out-of-limit values are visible immediately.
How do readings feed into reviews and reports?
The same readings drive WIDR diagnostics (wells above MOASP, wells missing recent readings), AI-assisted analysis, and integrity reports — so surveillance data does not need to be re-exported or re-compiled for weekly reviews.
