M8500 Ultra HPHT Dynamic Sagging Tester


 

 

The Grace Instrument M8500 High Pressure, High Temperature Dynamic Sagging Tester is designed for evaluating barite sagging and other weight material sag under simulated drilling conditions.

The M8500 Sagging Tester is engineered for safe testing while providing ultra high pressure and high temperature sag test conditions.

 

Data Integrity
The innovative design of the M8500 Sagging Tester accumulator piston prevents contamination of the drilling fluid inside the testing cell with pressurization fluid.

 

Control Parameters
A sample of drilling fluid is subjected to an adjustable temperature, pressure, rotor (pipe) speed and borehole angle for a set period of time.

Sample Extraction
Small amounts of the sample are taken from a defined collection site within the testing cell while maintaining temperature, pressure, and shear conditions. This method of sample extraction produces repeatable results.

Sample Characterization
The density and composition of the extracted sag samples can be measured. Other qualitative and quantitative analysis can also be performed.

The Grace Instrument M8500 is based on the hardware platform of the Grace Instrument M7500 Ultra HPHT Rheometer.

The patented M7500 Ultra HPHT Rheometer is capable of testing fluid viscosity under conditions of temperature and pressure ranging from atmospheric to 30,000 psi and from 20 °F (with chiller) to 600 °F.

More M7500 add-on modules:

 

M7500 add-on modules provide powerful new functionality at a lower cost than competing, stand-alone instruments, while maintaining a single instrument footprint and merging seamlessly with your existing software training.
