Evaluate the reuse of produced oil field water for irrigation, stockwater, or other potential uses such as industrial or municipal.
Treating produced oil field water is not a new concept. Several other states have been using treated produced water to alleviate the need for disposal of this waste product. Currently Kansas is injecting the excess produced water into the Arbuckle formation potentially causing future problems.
The Kansas Water Office (KWO) has submitted a WaterSMART grant proposal to the Bureau of Reclamation (BOR) for funding. The project would be located near Hardtner, KS where a collection tank for an injection well is located. The project will treat produced water for 60 days using Electrocoagulation, Reverse Osmosis and Desalination to bring this water down to acceptable levels for irrigation or stockwater. A sample collected in August of 2016 had chlorides at 120,000 ppm and boron at 17 ppm, these need to be reduced to 250 ppm and 4 ppm respectively.
Approval for the grant should come in late May of 2017. There will be some communication between the BOR and KWO prior to the final award with the project getting underway in the fall. The pilot project will operate for 60 consecutive days, and final reporting should be completed by spring of 2018.
The total project submitted to the BOR is for $1,299,175. Of this amount $1.1 million is in-kind in the form of equipment, owned by H20 Tech, needed to treat the produced water. Grant money requested from the BOR totals $199,175.
