M7500 Ultra HPHT Dynamic Rheometer


 

 

 

M7500-med.jpg

The Grace Instrument M7500 Ultra HPHT Dynamic Rheometer is a coaxial cylinder, rotational, high pressure, and high temperature rheometer. It is engineered to measure various rheological properties of fluids (including API HPHT tests) under a range of pressures and temperatures, up to 30,000 psi and 600 °F. An optional cement module is also available for testing the rheology of cements (see tab "Cement Rheometer", below.)

  • The M7500 is built with a thick-walled steel pressure cell, which is surrounded by a fail-safe steel containment vessel to ensure operator safety.
  • It is designed for easy test set up, sample loading and post-test cleaning.
  • Cool-down after tests can be accomplished more quickly by connecting a tap water supply or a chiller into the M7500’s cooling fluid loop.
  • Innovative patented design ensures against contamination of test sample with pressurization fluid.
  • Recently patented design eliminates the need for fragile and expensive "V" jewel bearings.

 

The M7500 is engineered for safe testing with extreme pressure and temperature settings:

  • safe operation
  • LCD display
  • sturdy
  • sample integrity
  • PC interface
  • digital
  • automatic
  • repeatable results
  • test flexibility
  • low maintenance

M7500PVT Ultra HPHT Pycnometer:

The M7500PVT Ultra HPHT Pycnometer module measures dilametric changes inthe density of a solid or fluid sample under conditions of temperature and pressure overa period of time. The patented M7500PVT Ultra HPHT Pycnometer replaces components of the M7500 Rotor/Bob assembly.

Patent Pending

M7500LSM Linear Swell Meter:

The Grace Instrument M7500LSM Ultra HPHT Linear Swell Meter is an add-on module for the M7500 Ultra HPHT Rheometer and provides an automated, ultra-high pressure and high temperature linear swell meter (up to 30,000 psi and 600 °F). Like the dedicated Grace Instrument M4600 HPHT Linear Swell Meter, it is engineered to measure the volumetric expansion (or contraction) of a solid sample under simulated downhole conditions while saturating it with a fluid sample.
Patent Pending

More specifications and other information can be found on our M7500LSM Linear Swell Meter page.

 


M7500 HPHT Cement Rheometer:

The HPHT Cement Rheometer is an engineered insert for the M7500 Ultra HPHT Rheometer that is designed for testing cement samples.

The cement sample is contained entirely within the rotor assembly, reducing contamination with pressurization fluid to a bare minimum. Once testing is finished, the rotor can be quickly disassembled for easy cleanup.

The patented design of the cement cell module eliminates jewel bearings, thus preventing measurement errors which can occur when bearings become contaminated with sample fluids.
