Atmospheric Consistometer Model 165AT

Designed to prepare cement slurries for testing various parameters in strict compliance with API Specification 10A/ISO 10426-1:2000

Clause 8 of API Specification 10A outlines the requirements and provides the procedure for conducting the Free-fluid Test (free water) using the Model 165AT Atmospheric Consistometer. The testing of cement slurries requires the measurement of thickening time, free water content, viscosity, rheological properties, fluid loss and various other properties.

The Model 165AT Atmospheric Consistometer provides a simple method for conditioning the cement slurries in preparation for performing these tests. This instrument is used in laboratories involved in oil well cement research programs, research and testing of cement additives, cement manufacturers quality assurance programs, and in the research for well servicing companies and their field labs.

HPHT Consistometer

The High-Pressure, High-Temperature (HPHT) Consistometer measures cement slurry viscosity or consistency under elevated pressure and temperature conditions. Its primary function is to determine the maximum available pumping time of a cement slurry before the slurry reaches an un-pumpable consistency before setting. While designed for cement slurries, the effects of pressure, time and temperature can also be observed for other fluids, emulsions, dispersions, or slurries under static or dynamic conditions.

The FANN Model 290 HPHT Consistometer exposes a cement slurry sample to a controlled set of parameters of temperature, agitation and pressure that simulate the down-hole conditions. During a test, these parameters are carefully monitored and precisely controlled by the system software.

A flat panel, High-Resolution, LCD touch-screen provides the interface between the user and the software. The LCD screen provides real-time viewing of temperature, pressure, and consistency data in graphic and text formats. This data is automatically recorded to a database for future analysis to help predict the cement slurry's down-hole performance.

Software Features

• Distributed Software; machine control code is run from embedded controller independent of front panel I/F computer
• Web enabled user intervace
• Software wizard for test setup
• Remote test control and monitor via LAN, Intranet, and Internet
• File Transfer Utility will not allow tests to proceed when embedded controller flash memory is full unless files have been moved or backed up to a network drive, thumb drive, or other media.
• Calibration Data is also protected by the file transfer utility
• Data Manager software allows viewing of test results locally or from remote computer with PDF printing capability
• Instrument calibration results are reviewable/printable with Data Manager
• Email test results from within software.

Safety Features

• Rupture disc for accidental chamber overpressure
• Automatic power shutdown if test temperature exceeds safe operating limits or if a break occurs in the temperature controlling thermocouple
• Rupture disc for accidental chamber overpressure
• Hardware indicator lights warn of temperature/pressure conditions
• Automatic power shutdown if test temperature exceeds safe operating limits or if a break occurs in the temperature controlling thermocouple
