Annulus Monitoring System

Product Overview

An Annulus Monitoring System (AMS) is a specialised oilfield monitoring system designed to measure, record, and analyse pressure changes within the annular spaces between casing strings, production tubing, and other well barriers. It plays an important role in well integrity management by helping operators identify abnormal annular pressure build-up, potential fluid communication, and conditions that may require further investigation.

Technical Specifications

The following are typical specification parameters. Actual values depend on the manufacturer, model, sensor selection, and application.

Parameter Technical Description

Measurement Annular pressure; optional temperature monitoring

Pressure range Application-dependent; commonly selected from low-pressure ranges to several thousand psi

Pressure sensor Electronic pressure transducer

Display Digital indicator or control-panel interface

Data logging Continuous or configurable interval-based recording

Alarm system Configurable high- and low-pressure alarms

Communication Optional Modbus RTU/TCP, HART, or other supported protocols

Remote monitoring Optional SCADA or control-room integration

Power supply Model-dependent AC, DC, or battery-powered options

Enclosure protection Selected according to environmental and installation requirements

Hazardous-area suitability Appropriate certification required where installed in classified areas

Installation Wellhead, casing/tubing annulus connections, or dedicated monitoring manifold

Note: The pressure range, accuracy, temperature rating, and certifications must be verified against the specific equipment datasheet before procurement or deployment.
