Real-time feature detection during operations

Page last modified

April 11 2024

ROSEN’s ACIM is a sophisticated tool designed to identify critical defects before failure with a high probability of detection. It monitors the tubing condition in real time and provides a clear, unambiguous and comprehensive analysis of the inspection data in an easy-to-read report. Corrective actions can then be scheduled, thus increasing operational efficiency. The resultant inspection data can be used to inform risk-based integrity decisions and more realistic remaining life assessments. It can also be integrated with other data sources.

Pros & Limitations

Confidence that coiled tubing is safe for operation

Accurate and reliable detection of metal loss and ovalities

Highly sensitive to even smallest defects, such as pinhole corrosion and mechanical damage

Real-time monitoring delivering immediate results on wall thickness, diameter, speed and depth

Designed for hazardous environments, including ATEX zone 1 for onshore and off shore operations

Cost savings and improved operating efficiency through avoidance of unscheduled downtime

Provision of vital input data for subsequent assessments, such as fatigue and remaining life assessments

Only works with magnetic materials like steel
