Foam & Core Flow Tester

M9300 HPHT Foam Loop & Core Flow Tester

  • The 9000 series products are all customizable.

The only integrated foam loop/core flow tester on the market today
The Grace Instrument M9300 HPHT Foam Loop & Core Flow Tester combines the operation of a foam loop system with a formation damage evaluation system. It can measure permability changes to a formation core in a high temperature and high pressure environment, after injecting the formation core with fluids, such as various foams, fracturing fluids, drilling muds, completion fluids and acids.

The M9300 can be operated in one of three modes:

  • HPHT Foam Loop Rheometer system can be used for foam creation, rheology and quality evaluation (bubble size distribution, half-life and density, etc.).

  • HPHT Automatic Core Flow Tester (Formation Damage) system can be used for core fluid treatments and permeability analysis.

  • Combined HPHT Foam Loop Rheometer & HPHT Automatic Core Flow Tester system is capable of measuring dynamic leakoff of foam, damage to the formation, well stimulation effects of foam, and rheology of foam in porous media.
