Model 4265HT

A Critical Tool for Oil Well Cement Testing
Testing the strength of standard cement cubes only provides information about cured strength. To accurately and effectively schedule a cementing job with a minimum WOC time, you need to determine how a slurry develops strength over time during curing. The Model 4265HT Ultrasonic Cement Analyzer (UCA) provides a determination of the strength development of a cement sample while it is being cured under very high downhole temperature and pressure conditions.

A Proven, Reliable Technique
Cement strength is determined by measuring the change in velocity of an ultrasonic signal transmitted through the cement specimen as it hardens. As the strength of the cement specimen increases, the ultrasonic signal’s transit time through the sample decreases. Using proprietary empirical algorithms that have been proven throughout the Oil and Gas Industry, the relative strength is calculated.

Operational Simplicity
The cement slurry to be tested is prepared in accordance with API recommendations, then placed in the unit’s temperature and pressure-controlled cell which simulates the curing conditions that are expected downhole. During testing, temperature is automatically controlled while pressure is manually set. For dynamic, precise pressure control, an automatic pressure system is available.

All test data including the compressive strength results are then transferred to a computer, running Chandler Engineering Model 5270 Data Acquisition Software.
