M4600 HPHT Linear Swell Meter



The only HPHT dynamic linear swell meter currently made in the USA
The M4600 HPHT Dynamic Linear Swell Meter is the only LSM in the world capable of high-pressure, high- temperature dynamic test operations. The patented design of the M4600 hardware allows core samples to expand in only one direction, making test results extremely repeatable.

Engineered to achieve highly repeatable test results
The Grace Instrument M4600 HPHT Linear Swell Meter is an automated, dual core, high pressure and high temperature linear swell meter (up to 2,000 psi and 500°F). It is engineered to measure the volumetric expansion (or contraction) of a core/wafer sample under simulated downhole conditions while saturating it with a drilling fluid sample.

The Grace Instrument M4600 HPHT Linear Swell Meter provides the most repeatable test results on the market today. It is the only HPHT linear swell meter available that is manufactured in the United States, and it has been designed specifically so that operation is both fast and easy. Quick sample loading and hardware setup optimize the testing process time.

Supplementary Dual Core/Wafer Compactor is available
The M4600 is also available with a dual core/wafer compactor so that drill cuttings, or other solids, can be compressed into a self-adhering core/wafer and tested in the M4600 HPHT Linear Swell Meter. Measuring the expansion (or contraction) of actual down-hole cuttings under HPHT conditions will yield data that is far more representative of downhole engineering applications than atmospheric testing alone. This allows researchers to design better fluids, project managers and technicians to make better fluid selection decisions, and QA personnel to identify potential problems with fluid and downhole solids interactions.

The M4600 includes M4600daq software for data acquisition. Test data collection can be customized in order to evaluate volumetric sample changes over various time quantities, and real-time data is displayed along with customized charts during the course of a test. Test data is easily exported into Microsoft Excel for report generating either during a test or after a test is completed.

Complimentary 2,850 psi hand pump is included with each compactor.
