SNF is a private company with a global presence strategically focused on growth in water-soluble polymers. In order to provide large volumes required for the fast growing Oil & Gas market, investment in additional monomer and polymer production capacities remain a major focus. New technologies are created in our state-of-the-art research centers to expand the limits of polymer applications, while helping customers reduce energy consumption, emissions, and costs.
High temperature-resistant polymers
SNF research has focused on improving polymer thermal stability up to 140°C, resulting in the SUPERPUSHER™ SAV polymer series. These are terpolymers containing N-Vinyl-Pyrrolidone that can sustain high temperatures and are efficient even in high salinity brines.
FLOCOMB™ 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 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 initial dissolution, through the surface equipment, and as it travels through the reservoir. Therefore, a reliable method is required to monitor viscosity at various points along the dissolution, dilution, mixing, and injection lines. This equipment must take into account non-Newtonian behavior, sensitivity to mechanical shear, and chemical degradation.
The patented FLOQUIP™ VDH In-Line Viscometer is 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 degradation. The device has been designed to solve common problems encountered with other currently available commercial equipment. It allows operators to gather reliable data inline instead of by manual sampling methods, which are difficult to conduct without degrading polymer solutions.
SNF is focused on achieving innovation through continuous Research and Development, as well as collaboration with universities and participation in several Joint Industrial Projects (JIP).
