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 produced water into the Arbuckle Formation where remaining disposal capacity in areas is becoming a growing concern. The Kansas Water Office (KWO) submitted a WaterSMART grant proposal to the Bureau of Reclamation (BOR) for funding which was selected for award. The project will 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 a one of a kind piece of equipment 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 to meet stockwater requirements.
The equipment has been fabricated with
reassembly nearly completed after special coatings were applied to separate
sections of the unit. Testing at the fabrication facility will take place
within the next two weeks and then the unit will be transported to the site
near Hardtner, Kansas.
The total project submitted to the BOR is $1,299,175. Of this amount $1.1 million is in-kind in the form of equipment needed to treat the produced water. Grant money requested from the BOR totals $199,175.
