Treatment and Recycling
From automated water recycling systems that economically process alternative types of water to providing on-the-fly water treatment technologies that eliminate bacteria and sulfides prior to fracturing operations, we help ensure consistent water quality throughout completion operations.
A key challenge for operators is the wide variance in water quality and consistency. Addressing this challenge requires planning to determine initially how the water is treated and to what level before using it in fracturing operations. Our automated water treatment and recycling systems are developed specifically to handle the high variability inherent in non-potable water supplies, including subsurface saline water, produced water, and effluent water.
Selective chemical treatment, filtration, and blending from TETRA work together to provide water that is free of bacteria and scale forming solids before pumping it downhole. Our custom-designed, patented blending manifold delivers consistent, homogeneous frac water and allows dispersion of additives ahead of the working tanks. Treatment additives are fast acting, quick degrading, selective biocides that eradicate bacteria as frac water moves through the tanks.
We recommend our dual pod sock filtration units for filtering brines, gels, chemicals, and produced water in completion, stimulation, and workover operations. The pods are designed for high rates and high volumes and are meant to keep pace with today’s current stimulations. Sock filtration is designed for use with fluids containing a high percent by volume of suspended solids.
Our units economically filter large fluid volumes at rates greater than 60 bpm/pod and are easily operated by personnel already on location. Real-time adjustments ensure adequate treatment and performance validation. Complete pre- and post-job water analyses are available through our laboratory services.
Recovering Residual Hydrocarbons
TETRA Oil Recovery After Production Technology (ORAPT™)
Our ORAPT oil separation system pretreats produced water before recycling it. Standalone ORAPT mobile units remove native oil, undesired light constituents, and oil slugs caused by unplanned bypasses from production facilities to deliver water with only trace amounts of oil at 50-100 ppm. The recovered oil is returned to the operator for sale. Nominal throughput of this system is 25,000 bbl/day.
Automated Water Treatment
SwiftWater Automated Treatment (SWAT™) System and On-the-Fly Water Treatment
Chemically treats produced water through a clarification process that enables recycling of up to 100,000 bbl/day of produced water with a single system. We build custom systems to handle larger volumes. Our web-based, real-time monitoring and control technology provides you with 24/7 access to treatment and recycling operations. This provides a transparent and on-demand view of the chemistry applied to treat the water and its effectiveness.
Our on-the-fly water treatment system treats both the produced and fresh water with EPA-approved biocides to prevent or eliminate 100 percent of bacteria. Biocides remove bacteria and sulfides prior to fracturing, providing continuous, accurate chemical dosage volume. Because the system generates biocides through the flow of water in the transfer line, the unit stops when flow stops to ensure a safe working environment.
