Produced waters typically contain high levels of dissolved solids ranging in salinity from 12 to 180 parts per thousand, metals concentrations higher than those of receiving waters, and up to 25 parts per million (ppm) oil and grease.

Global Industrial Water (GIW) is endeavoring to find a treatment or series of treatments whereby produced water from oil and gas operations can be rendered fit for reuse, agricultural, municipal and industrial use. This potential new water supply would:
- alleviate the pressure on conventional water supplies,
- provide an environmentally friendly alternative to re-injection (PWRI), and
- be drought-proof.
The aim is to supply water treatment equipment to oil and gas producers in order to save money, reduce fresh water requirements for drilling and minimize contamination of water supplies.
These are the costs today to supply water for drilling, per well:
Cost to truck water to each well per 100,000 barrels of water - $487,000
Cost per well to treat and recycle 100,000 barrels of water - $324,000
IMMEDIATE SAVINGS $163,000 PER FRAC PER WELL
(Each operator performs around 40 – 60 fracs per well per month so an oil producer could save as much as $10,000,000 per well per month by re-using the injection water.)
In addition to the cost saving benefits of treatment and re-use of water there is a truck load reduction of 295 truckloads required per well which equates to a 36% reduction of trucks on the road.
The intention for the upcoming trial is to treat produced water at a rate of 10gpm and render it fit for agricultural, municipal, industrial use and re-use for injection/ fracking.
Each of the water treatment components in this study has been proven effective in its own right.
The purpose of our study is to create varying sequences of equipment using 3 or 4-way valves.
The feed water will be directed through each component in documented permutations.
The water quality will be analyzed after each run by means of sample ports.
The findings of each permutation will be analyzed to identify and measure the constituents of the water after treatment.
The study will commence on August 12th and will run initially for 14 days. Many prominent oil producers and invited guests will be in attendance to witness the performance of the various technologies and the intention is to extend the duration of the study to provide additional information relating to areas of specific interest, if so required.
In addition to a full, on-site laboratory facility the study will also be determining:
1). Oil in water concentration and particle size with state of the art fluid imaging technology capable of microscopy, ultrasonic lens cleaning and laser induced UF fluorescence.
2). The efficacy of membrane technology
3). Whether a produced water treatment train using green technology can be developed commercially to create a cost-efficient method of reclaiming produced water for stream-flow augmentation, irrigation, livestock watering, and municipal and industrial use
4). How practical an appropriately sized treatment train would be in a real time application
5). The viability of the re-sale of oil reclaimed from produced water
6). The suitability of 000 rated chemicals as a means by which to flocculate heavy metals in order to reduce TDS and to remove H2S
A new mechanically cleaned micro filter for the removal of biologicals and a low pressure direct displacement ZeeWeed ultra filter will be introduced by the Texas A&M University together with new wireless air emission monitors.
The facility has all amenities, including conference room, Wi-Fi, restrooms, break room, air conditioning, lock-up facilities and telephone. There are several hotels within 10 minutes of the facility including Best Western and Comfort Inn.
