Fann HT UCA (High-Temperature Ultrasonic Cement Analyzer) Model 520 is used to provide an indication of the relative strength development of a slurry sample while being cured under downhole temperature and pressure conditions. Relative strength is determined by measuring the change in velocity of an ultrasonic signal transmitted through the cement slurry specimen as it cures. As the strength of the cement specimen increases, the transit time of the ultrasonic signal through the specimen decreases, allowing the relative strength to be calculated.
The Model 520 is able to test cement slurries at temperatures up to 500°F and pressures as high as 20,000 psi.
