Consistometer The Model 290 (HPHT)

The Model 290 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

The HPHT Consistometer Control Software is the next generation of complete and powerful system control software with a simple and friendly, flexible user interface.

• Touch Screen with Friendly and Flexible User Interface
• Unlimited storage for test data
• Remote Test control & monitor via LAN, Intranet, and Internet
• Email test results from within software

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.
