Paratene™ WF “Water Foaming Agent” Description Paratene™ WF is a blend of foaming agents and stabilizers specifically designed to provide high activity and optimum foaming in a wide range of well environments including fresh water, light to heavy brines containing high concentrations of calcium and magnesium, and in water contaminated with oil. Paratene™ WF can be used for unloading excess formation fluids in gas wells, coil tubing clean-outs, and for air/foam drilling operations. Features and Advantages - Foams fresh water - Foams saturated brine - Foams in presence of oil - Foams HCL Acid - Excellent foam stability - Excellent foam quality - Excellent foam height - Freeze-Proofed to Minus 40°C Typical Physical Properties Appearance Clear Liquid Specific Gravity 0.96 Flash Point None pH 8.5 Freeze Point -40°C Ionic Character Anionic Methods of Application Paratene™ WF is typically added directly to water at a concentration of 0.3 – 2% to generate a foam with air, nitrogen or carbon dioxide. Paratene™ WF can be added directly to a gas well by pouring it into the annulus. The well can then safely be unloaded. Test Data Foam height and half-life are measured with 100 ml of fluid and a loading rate of 1.0% by volume. Fluid Foam Height (ml) Half-Life (min) Fresh Water 1010 4.5 1% NaOH 950 5.0 1% CaCl2 & 1% NaCl 1050 4.0 5% Oil in water 905 5.0 15% HCL Acid 850 6.75 Safety and Handling Paratene™ WF is flammable and toxic and should be handled with care. Contact may be irritating to the eyes and skin. Refer to the material safety datasheet for additional information. Woodrising Resources Ltd. #2 321 37 Ave. N.E.
