Filtration of wastewater is a tricky business. Balancing disposal and/or water reuse is a constant struggle in the oilfield.
Economically sourcing fresh water isn’t easy. Socioeconomic concerns combined with geopolitical forces have created water shortages across the globe. Access to fresh water is increasingly difficult to secure for operators everywhere.
From the Bakken to the Eagle Ford to international operations, finding quality water continues to be the proverbial throne in many operator’s sides.
We founded Resirkulere to fill this gap in the marketplace.
Resirkulere’s Solution to the Filtration of Water Problem
Resirkulere’s Wastewater Filtration System uses a physical separation process to remove suspended solids and create production quality water on the spot. It removes solids like frac gels and proppant and makes filtration possible.
- 99% reduction in Total Suspended Solids (TSS) Breaks emulsions
- Fully portable
- Maintenance free
- Operator supplied
We pass returned contaminated water created during coiled-tubing drill outs, rig-assisted plug drill outs, and other clean out operations through the specialized separator. This process mimics the retention time equivalent to “flocking” the water hundreds of times.
This allows the chemical gels which suspend the sand and other proppants enough time to “break out” of suspension. Increased retention also give oil and other hydrocarbons an opportunity to separate from the emulsion. As a result, it can be saved, while also eliminating the tendency for these materials to plug the filtering medium.
In this way, water is prepared for filtering and reused for physical applications (such as during plug drill outs) while retaining the valuable sellable oil. Heavier coagulants and sand sink to the bottom of the specialized separator where they pass through sock filters (generally 25 micron), leaving clear water, suitable for reuse in drilling and production operations.
The Resirkulere Wastewater Filtration System is most effective at treating the following contaminants:
- Total Petroleum Hydrocarbons (TPH)
- Resirkulere water treatment effectively removes oil from non-contaminated water
Filtration of Wastewater While Reduced Environmental Footprint
Resirkulere’s specialized separator creates produced and flowback water you can reuse in fracturing and drilling fluids.
This minimizes the volume of wastewater sent to disposal. Again, reducing demand for freshwater.
Operational efficiency has become a major business-driver for all operators. Reduced truck use offers oilfield operators a quick win. On average, each specialized separator eliminates 4,320 barrels of fresh water and 4,320 barrels of disposal per day.
That’s roughly 72 truckloads of water, 8,640 miles of truck traffic, and 144 hours of road time.
Another area of savings is trucking. Not only in drastically reducing milage, but also by boosting HS&E metrics. With less trucks entering and leaving the wellsite, oilfield employees and local residents are that much safer.
We’ve found the investments in our closed loop system for the filtration of water are drastically offset in myriad ways. Recovering more oil, reducining truck traffic, increasing disposal efficiency, and minimized freshwater acquisition, just to name a few.
Operational Efficiency Applications
Resirkulere’s mobile solution for filtration of wastewater generally operates as high as 18 to 20 bbls per minute. It’s also easily scalable for any size project to quickly treat the large volumes of water.
It has been successfully deployed in plug drill outs, coiled-tubing drill outs, and several other field applications.
The specialized separator was designed to remove suspended solids, oil, and other insoluble organics from wastewater. It works extremely well with coiled-tubing operations.
However, several clients have applied it as a first rendering for clarification. By knocking suspended solids out of emulsified “trash” water many have transformed their operations by quickly producing production quality water on the fly.
