AUSTRALIAN fine particle and water management company Reynolds Soil Technologies (RST) has designed a hydrocarbon-free polymer friction modifier solution, to help aid the extraction process and reserve energy of oil and gas being transported from great depths after fracturing.
Known as Jetstream, the oil-free friction reducer increases flow rates in water and brine-based fracturing applications using RST’s polymer dispersive technology for aqueous fracturing fluid.
Jetstream contains no hydrocarbons, mineral oils or surfactants – minimising potential environmental issues and helping to ensure the safety of workers – and is supplied ready to use, eliminating the need for special mixing or dissolving equipment onsite.
RST operations and technical director David Handel said current products being used to reduce friction, including standard polymer emulsion and powders were not always either safe or effective.
“Polymer emulsions, though effective, generally contain a mix of hazardous materials including surfactants, hydrocarbons and mineral oils which have many environmental constraints, while powders have significant limitations as they require specific equipment as well as a large energy and water supply to ensure the product is properly diluted and applied,” he said.
“Jetstream effectively changes the rheological properties of the fracturing fluid, increasing flow rates without increasing operating and surface treating pressures and as a result extracts oil and gas from great depths, using much less hydraulic energy generally needed for pumping.”
Dosing rates range from 25 – 2500ppm based on the aqueous fracturing fluids, however the company advises best results are typically achieved between 100 300ppm – though levels can be adjusted to meet client needs.
Additional benefits of Jetstream include quick hydration, high salt resistance performance, fast dissolution when injected into an energy mixing zone and excellent friction reducing qualities, the company said.
