Description: Viscometer is designed to measure rheological properties of drilling fluids under extreme high pressure and high temperature (XHPHT) conditions like temperatures up to 600°F (316°C) and pressures up to 40,000 PSIg (2758 bar). The new viscometer is one of a suite of highly specialised instruments designed to support oil and gas exploration. It was developed to provide profiles at temperatures and pressures beyond the capabilities of currently available equipment.
