SNF has a range of more than 1,050 products and launches approximately 100 new polymeric compositions every year. Taking our products from the lab bench to full-scale production is something we do on a regular basis. Our R&D and engineering teams have the ability to mobilize resources very readily, allowing us to bring our customers’ concepts or problems from lab trials, to pilot scale-up tests, up to full-scale production quickly and efficiently. SNF has a unique level of integration, starting from monomer production, up to injection equipment, as well as surface facilities.
At SNF we fine tune every polymer we sell into oilfield applications whether it be related to molecular weight (to enable good injectivity), sweep efficiency, low retention, or compatibility with other chemicals. In some cases, our polymers are formulated with protective additives, either internal or external, to maintain the integrity of the polymer and its performance. All the aforementioned parameters are field-specific and require balancing performance with cost. In fact, SNF has conducted more than 40 customer specific application tests over the past 5 years. These tests include modifications of our polymers for molecular weight, physical form (solid or liquid), solids content, surfactant inversion package, incorporation of various functional monomer(s), and/or packaged polymers with protective additives against iron, oxygen leaks, H2S, etc…
With two research centers dedicated to Oil and Gas related applications (Andrezieux France and Riceboro USA), SNF has the capabilities to perform extensive testing related to polymer characterization, synthesis and application:
- Polymer synthesis and optimization
- Core floods
- Long-term thermal stability
- Aging in fully anaerobic conditions using glove boxes
- Quality control (HPLC, GC, viscosity etc).
SNF has dedicated facilities to test in real conditions several parameters related to polymer processing. This includes dry polymer dissolution or liquid emulsion polymer inversion units, flow loops, inline viscometers, portable injection units. All systems required for polymer processing or handling can be tested at SNF in a short period of time, with the assistance of skilled and dedicated professionals that know how to handle polymers.

SNF is a privately-held company with a global presence, strategically focused on growth in water-soluble polymers. In order to provide the large volumes required for the fast growing Oil and Gas markets, investments for additional production capacity of monomers and polymers remains a major focus. New technologies are created in our state-of-the-art research centers to improve the limits of polymer applications and to help enable our oilfield customers to operate faster, safer, and more economically.
HIGH TEMPERATURE-RESISTANT POLYMERS
SNF research has focused on improving polymer thermal stability with the creation of the SUPERPUSHER® SAV series of polymers to work in oilflield application greater than 120°C. These are terpolymers containing N-Vinyl-Pyrrolidone, which can sustain high temperatures and are efficient even in high salinity brines.
|SERIES||AMOUNT OF FUNCTIONAL MONOMERS||MAX. TEMPERATURE|
|Superpusher SAV 37||low||105°C|
|Superpusher SAV 225||medium||110°C|
|Superpusher SAV 10||medium||120°C|
|Superpusher SAV 333||high||140°C|
SNF’s FLOCOMB® series polymers have been developed for use in harsh conditions, specifically for high salinity brines. In solutions containing high levels of hardness the polymer molecules can coil up and precipitate causing a loss of viscosity and formation plugging. The Flocomb Series was created as a remedy for these cases.
Flocomb C6200 series
Medium to high
Flocomb C6500 series
Medium to high
Flocomb C6700 series
FLOCOMB® polymers yield higher viscosity compared to standard HPAM, especially in very saline brines ( salinity 130 g/l, divalents=7 g/l, T=40°C, polymer concentration = 2000 ppm).
Viscosity is the key factor for a successful polymer flood and it must be maintained from the initial dissolution, through the surface equipment, and as it travels through the reservoir. Therefore, a reliable method is required to monitor it at various points along the dissolution, dilution, mixing and injection lines. This equipment must take into account the polymer solution characteristics among which are non-Newtonian behavior and sensitivity to mechanical shear and chemical degradation.
The patented FLOQUIP® VDH Inline Viscometer™ is a patented device designed to continuously measure the viscosity of polymer solution on the surface before it is injected into the reservoir. Viscosity is measured at a low shear rate indicative of actual reservoir flow rates. The FLOQUIP VDH allows stable and accurate viscosity measurements without sample degradation. The device has been designed to solve the common problems encountered with currently available commercial equipment. It allows operators to gather reliable data inline instead of the manual sampling methods that are difficult to obtain, as well as to conduct, without degrading the polymer solution.
In addition to our internal research, SNF collaborates with and sponsors several universities around the world and participates in Joint Industrial Projects (JIPs) as a commitment to continuous innovation.
