In today's complex wellsite environment, coiled tubing failure can occur as a result of mechanical damage due to erosion, corrosion, tensile overload, and abrasion. These failures are not only costly, but time-consuming for both the service provider and the well operator. The Argus TubeSpec is a unique, patented, ultrasonic, coiled tubing measuring device. The unit provides highly accurate, frequent, circumferential coiled tubing wall-thickness measurements as the tubing passes through the inspection device during field operations. These measurements allow the user to evaluate the coiled tubing's wall thickness along the coiled tubing string.

While most Ultrasonic Transducer (UT) methods require clean water to couple the ultrasonic probe to the material measured, the Argus TubeSpec uses a polyurethane element as a medium between the sensor and the coiled tubing, therefore eliminating the need for water coupling.

The polyurethane element (a solid) exhibits excellent wear characteristics. When compressed, the element transforms to exhibit the attributes of a liquid, filling changes in the surface contour of the tubing. The polyurethane element is therefore not contaminated by the environment, and accurate circumferential wall-thickness measurements can be made.

The Argus TubeSpec performs coiled tubing wall-thickness measuring techniques in the field environment, including:

• Providing continuous, accurate, localized wall-thickness measurements using 12 ultrasonic probes.
• Providing continuous diameter and ovality measurements.
• Tracking weld-seam location to monitor rotation of the coiled tubing.
• No calibration needed to measure wall thickness.
• Horizontally split for installation on coiled tubing; no need for dangerous stabbing-through of tubing.
• Complete unit weight, excluding mounting bracket and electronics: 66.5 lbs.
• Hazardous-area certified.
