... Abstract Accurate estimation of the wellbore equivalent circulation density (ECD) is crucial for effective well planning and drilling. This paper introduces a portable and compact hardware designed to study the two-phase annular hydraulics of arbitrarily inclined wellbores, providing detailed...

... for eventual commercialization. The mechanical hardware was improved for 20,000 PSI operation. Also of importance was the need to determine the "automated capability" required in the user interface, so as not to require an acoustic expert to run the system. After further successful testing in June 1992...
