Grace Instrument has developed a hardware module for the M7500 Ultra HPHT rheometer that provides a means for testing liquid density changes under simulated down-hole conditions.
These conditions include those found in deep oil or geothermal wells.
The M7500PVT Ultra HPHT densitometer module is also designed to test solid samples such as cements, cores or other solids.
Both sample types can be tested without contamination by pressurisation fluid.
The M7500PVT module includes two pistons: large and small.
The large piston is intended for tests involving larger changes in sample density, while the small piston is intended for tests involving smaller changes in sample density with a corresponding need for greater accuracy.
These tests are created and administered by the user with the M7500 PC software, M7500DAQ.
Test results are displayed within the software, and can be exported directly into Microsoft Excel, or saved as a standard .CSV text file.
