High Pressure Viscometer: VISCOlab PVT

High Pressure Viscometer

The VISCOlab PVT viscometer is designed for elevated pressure and temperature measurement in research & development, reservoir fluid and core sample analysis, and supercritical fluid studies. This high pressure/high temperature viscometer requires less than 6 ml of sample per measurement and cleaning; measures gas and gas condensates in addition to fluid sample; provides statistical certainty that ensures that sample conditions are stable, accurate, and repeatable; incorporates a digital pressure gauge; and is mercury free. Combining a VISCOpro 2000 processor with a Cambridge Viscosity SPL440 sensor, the VISCOlab PVT series also incorporates a high-temperature fluid management system.

VISCOlab PVT Recirculating Bath System

The VISCOlab PVT Recirculating Bath System is the industry standard, controlling pressures to 20,000 psi, temperatures from -30 to 190º C with a recirculating bath for minimal warm-up time. Sample flow is controlled with a simple three-valve plumbing configuration, and the standard test set-up includes horizontal, 45-degree, and vertical configurations for ease of operation. This system includes an intuitive graphical user interface for simple integration of the bath, pressure gauge, and viscometer.  This intuitive interface logs data from all of these sources to graphically display their values in real time!

New Developments

Oil exploration is expanding into more extreme environments to meet continuing growth in world demand. Safely capitalizing on these opportunities is a challenge. The economics of an oil field are significantly impacted by the porosity of the rock structure and the viscosity of the reservoir fluid which can be thousands of meters away from the drilling rigs and under the oceans. These conditions increasingly involve reservoir fluids at pressures and temperatures not previously encountered.

Working closely with the industry, Cambridge Viscosity is continuously pushing the state of the art to meet these challenges, with innovative technology for accurate, reliable, small sample viscometry.

Ultra High Pressure Viscometer

Deep water Drilling deep under the earth surface such as in deep water, increases the pressures on the reservoir fluids, and thus the requirements for reservoir fluid analysis tools.  Our standard VISCOlab PVT viscometer has a maximum pressure rating of 20,000psi (1,400bar). The increasingly demanding environments the industry is now facing are driving the requirements well above this level. Responding to these new needs, Cambridge had developed a new high pressure viscometer, our VISCOlab PVT-HP, which is rated to 43,000 psi (3,000bar).

Ultra High Temperature Viscometer

New oil recovery techniques are being developed for oil sands. The steam assisted gravity drainage method (SAGD) and other approaches require viscosity analysis performed at extremely high temperatures to be used effectively.  Cambridge is meeting this need with the VISCOlab PVT-HT, our new extra high temperature viscometer version of our VISCOlab PVT that allows for high pressure viscosity analysis at temperatures up to 315° C.
