Amplifrac Advanced Proppant-Suspension Fluid System
Optimize proppant placement, enhance reservoir contact, and maximize production
Unconventional and tight-oil and gas reservoirs require stimulation to create conductive flow channels. The goal is to open as much of the low-permeability reservoir as possible—and then keep it open.
The Weatherford Amplifrac™ advanced proppant-suspension fluid is a low-viscosity, elastic fracturing fluid system that maximizes proppant-carrying capacity while reducing injection-horsepower requirements. Unlike conventional hydraulic fracturing fluids that rely on crosslinker or slickwater treatments that can become highly viscous or unsupportive, the Amplifrac fluid system generates fractures that reach farther into the reservoir payzone and enhance reservoir conductive volume.
The Amplifrac fluid system delivers enhanced fracture stimulation with engineered chemistries tailored for your reservoir conditions. Our advanced fluid technologies maximize proppant transport, improve wellbore stability, and optimize hydrocarbon recovery while minimizing formation damage.
Designed For Your Reservoir
The Amplifrac fluid system was created to meet the demands of your fracturing operations. Designed to improve fluid efficiency, reduce friction, and optimize formation interaction, our fracturing fluid system enables effective multistage fracturing across diverse reservoir environments.
Fluid properties, such as viscosity, density, proppant type, and concentration, can be modified or even redesigned to achieve higher proppant-carrying capacity, no proppant settling during injection and fracture closure, and better stability based on the specific reservoir and injection conditions.
Fluid and proppant design is analyzed in a reservoir scale model using an advanced geomechanical and production engine. Geomechanical models can evaluate hydraulic fracture propagation, natural fracture reactivation, and proppant transport within hydraulic fractures and the reactivated natural fracture network.
Advance Your Fluid Performance
The Amplifrac fluid system is effective in reservoir permeabilities up to 0.3 mD and static temperatures up to 240°F (116°C). It is compatible with most common clay-control additives, biocides, and breakers. No additional additives, such as crosslinkers and buffers, are required to generate proppant suspension. When used in fresh water or light brine, the Amplifrac fluid system will reduce friction-pressure by as much as 60 to 70% at low dosages. Applications may include slick-fracturing or serving as an alternative to crosslinked-fluid fracturing. Breakers can adjust flowback times and increase cleanup performance of the proppant pack, thus increasing regained permeability.
The Weatherford Amplifrac fluid system gives you distinct advantages over conventional frac fluids:
- Longer effective fracture lengths and larger conductive reservoir volume
- Less surface horsepower per ton of proppant placed
- Enhanced fracturing efficiency and ultimate production
