Quality Control and ISO Certification.

SNF is ISO 9001 certified for all products manufactured in SNF plants in France, the USA and China. Very high quality polymers are required for Enhanced Oil Recovery (EOR) applications, therefore, each batch of EOR polymer is carefully tested in our QC laboratories. These, consist of routine tests such as UL Viscosity (test procedure SNF QC 400A), Active Content (SNF QC100A), particle size, free monomer content and can include further EOR related tests such as viscosity measurement at field conditions (injection brine, temperature, concentration), filter ratio and percent hydrolysis (anionicity).


More specific tests are conducted on a reservoir study basis to evaluate the following parameters:

• Thermal stability under reservoir conditions (anaerobic)
• Shear resistance
• Chemical stability and compatibility with oxygen scavenger, iron chelating agent, etc.
• Screen factor
• Injectivity, adsorption and oil recovery in sandpacks and core floods with actual reservoir core material
• For emulsion products invertability is optimized for specific field conditions (brine salinity, temperature of makeup water)

 

Quality Control

Customer satisfaction has always been SNF’s first priority. Over the years, this primary objective has become the focus of every employee from the production to the accounting departments. SNF has set several guidelines in order to efficiently answer customer’s requests.


SNF’s six main guidelines are:

• SIMPLE
• FAST
• HIGH PERFORMANCE
• LOWEST COST
• In compliance with APPLICABLE REGULATION
• CONTINUOUS IMPROVEMENT

Quality control of all EOR products is necessary in every step of the process. SNF has designed quality control specifications and procedures for EOR applications :

• Activity level
• Hydrolysis level
• Viscosity in synthetic field brine
• Filterability - Injectivity
• Free monomer
• Thermal stability
• Solubility
