iX77™ Rheometer

Shale Tech Solutions SRL distribuidor exclusivo de FANN para la Argentina

The FANN® iX77™ HPHT Rheometer has emerged as a very robust and accurate instrument for testing rheological properties of drilling fluids at 600°F and 30,000 psi.  While the expanded range of temperature and pressure is in itself a compelling reason to use the iX77 Rheometer, the instrument offers numerous features that improve accuracy and efficiency.

Complete Automation with User-Friendly Software

The iX77 Rheometer is fully automated and comes equipped with user-friendly software that helps the operator set up the test parameters (“test sequence”) and designate the output types and timing.  A full-capacity computer is integrated into the Rheometer so that test progress can be viewed at any time on the integrated touch screen monitor.

After the cell is assembled and filled with the drilling fluid sample, the user loads the desired test sequence (or generates a new test sequence if required) and simply clicks the “Start Test” button.  The instrument does the rest on its own, including sending email notifications to the user and others who are designated to see the results.  The outputs are delivered in CSV format, and while the test is running, the user can zoom in on a particular temperature/pressure combination, view raw data, call up graphical displays and generally monitor all aspects of the test.
