Pressurized Foam Rheometer Measures Foam Properties Over Extended Range of Pressures and Temperatures

Chandler Engineering's Model 8500 Is an Advanced Well Completion Tool

BROKEN ARROW, OK - The oil and gas industry has greatly increased its use of drilling foams. However, safe and economical use of these foams depends heavily on an understanding of how the foams will perform under the wide range of pressures and temperatures typically found in drilling operations.

Chandler Engineering®, a leader in oil well cementing, viscosity, reservoir analysis and high-pressure, high-temperature instruments, has specifically developed the Model 8500 pressurized foam rheometer to measure the rheological properties of foamed systems under extended pressure and temperature conditions.

The Model 8500 is a fully automated closed loop system, including both hardware and software, for the study of foam rheology over a wide range of foam qualities, shear rates and shear stresses. The Model 8500 utilizes a calibrated volume in calculating the foam quality. The system software is designed to allow the operator to automate the system using schedules that define shear rates, sample test temperatures and test segment durations.

The Model 8500 incorporates a pulse-free positive displacement Quizix(TM) precision metering pump for injection of the base fluid and volume determination. Differential pressure transducers are provided to cover a wide range of shear stress measurements. Flow and shear rates are measured using a coriolis mass flow meter. The shear loop, mass flow meter, positive displacement pump, foam generator and view window are contained within a convection oven, providing uniform temperature control of these components.

An integrated high-pressure view window allows visual determination of foam quality, stability and bubble distribution. An optional camera and image acquisition system is available for video capture and image analysis of the foam through the view window.

Chandler Engineering focuses on serving the upstream oil and gas markets in exploration and production. Its products are used for oil well cementing, viscosity measurement, reservoir analysis and other HPHT applications such as pipeline transmission. Chandler Engineering is part of the AMETEK Oil & Gas Business Unit. AMETEK®, Inc. is a leading global manufacturer of electronic instruments and electromechanical devices with annual sales of $3.0 billion.
