Our seasoned team guides you through Bottom-Up or Top-Down methods, pinpointing the perfect approach for superior product contact. And for anticipated re-injection, we recommend durable permanent wells, customized to your needs.
With real-time pressure and flow monitoring, we keep a vigilant eye on performance, ensuring success below the surface. Choose Vista for precision, reliability, and unmatched expertise in injection solutions.
NEW! Clean-Inject™ Remediation System
Self-Contained Slurry Mixing and High Pressure Injection System
Our new Clean-Inject® System offers a self-contained, robust mixing and injection solution for various powdered reagents, including activated carbons, oxidants, and other materials requiring suspended slurry and precise injection methods for optimal performance. By utilizing super sacks of reagents pumped directly into the mixing tank, we eliminate unnecessary exposure to personnel and surrounding property.
Paired with our Surgical Injection Tooling, this cost-effective system enables precise placement of slurry material at narrow depth intervals. High-pressure, high-flow-rate pumps can effectively overcome formations of all types, from tight clays and claystone bedrocks to loose unconsolidated sands and gravels—common challenges for other pumping systems used with slurries. Our injection tooling and methods are optimized to minimize surfacing and because of this, the material remains in the contaminated and saturated formation where it's most effective.
In Situ Remediation
With top-down injection methods, the amount of material injected can be varied by as tight as one foot intervals from the top of the contaminated interval to the bottom utilizing expensive reagents more efficiently and ensuring their effectiveness. Combined with better Remedial Design Characterization (RDC) and best the practices, treatment placement and coverage is now optimized. Contact us for further information on Clean-Inject System Specifications for your environmental remediation in situ project needs.
Why would I need Hydraulic Fracturing?
Hydraulic fracturing, a patented technology, involves injecting combinations of slurried proppants, chemicals, or bio-amended solutions into tight soils and bedrock at high pressures to create fractures at environmental remediation sites. These fractures increase permeability, facilitating the distribution and contact of remedial solutions, commonly used for ISCO, ISCR, ISBR, and SVE applications. Various proppants like sand or synthetic materials are used to hold the fractures open and host bacteria.
Struggling to meet clean-up levels? Is poor air sparging or soil vapor extraction hindering closure? Hydraulic fracturing could be the solution. Vista GeoScience pioneered hydraulic fracturing in the Rocky Mountain area in the 1990s and holds the sole license for remediation. With expertise spanning globally, Vista injects a range of products into fractures, including permanganates, oxygen enhancers, lactates, peroxides, ZVI slurries, EVO emulsions, and bacteria suspensions.
Customized Fracturing Equipment & Real-Time Monitoring Systems
Vista tailors fracturing and proppant injection system designs to suit different geologies, contaminants, and treatment solutions. Depending on these factors, we employ various fracture techniques and utilize progressive cavity pumps, piston pumps, diaphragm pumps, and mixing systems. We provide real-time monitoring throughout the fracture creation process. Our system empowers engineers to map and control fracture propagation while simultaneously plotting the fracture position over time. This capability is particularly crucial for situations involving fractures beneath residential or commercial sites, where determining effective ROIs is essential for comprehensive remedial designs and regulatory approval.
