Acid stimulation under reservoir conditions
The Grace Instrument M9400 Automatic Rotating Disc Acid Reactor is designed to analyze acid stimulation performance under reservoir conditions. The M9400 is capable of testing hydrochloric, hydrofluoric and organic acids used for acid stimulation of carbonate and sandstone reservoirs. The rotating reactor puts the rock sample in motion for uniform reaction with the acid system.

Safe, reliable, hands-free operation
Designed to maximize user safety, the M9400 features completely automatic, hands-free operation after the user loads the test samples. Additionally, steel safty shield towers enclose the pressure vessels, with a surrounding splash shield providing further protection to the user and the working environment.

This M9400 features a 1'' diameter rotating disc and a magnetic drive system enclosed in a Hastelloy 10,000 psi pressure vessel. It also includes temperature control, reactant fluid collector and data acquisition and control system.

During an experiment, pressure, temperature, acid displacement and test duration are all software controlled. Further, the easy-to-use software allows the collection of numerous reactant samples at preselected time intervals. The necessary accessories are meeting HSE required standards.
