Method For Generating Fracturing Water
US Patent:
7527736, May 5, 2009
Filed:
Mar 13, 2007
Appl. No.:
11/685681
Inventors:
Lee L. Shafer - Big Piney WY, US
John W. James - Boulder WY, US

Assignee:
Anticline Disposal, LLC - Rapid City SD
International Classification:
C02F 3/00
US Classification:
210620, 210621, 210622, 210630, 210631
Abstract:
Systems and methods have been developed for reclaiming water contaminated with the expected range of contaminants typically associated with produced water in order to produce a treated water having a quality adequate for reuse as a fracturing water. The system includes anaerobically digesting the contaminated water, followed by aerating the water to enhance biological digestion. After aeration, the water is separated using a flotation operation that effectively removes the spent friction reducing agents and allows the treated water to be reclaimed and reused as fracturing water, even though it retains levels of contaminants, including boron and methanol, that would prevent its discharge to the environment under existing standards. The treated water has had a sufficient amount of the gellation-inhibiting contaminants, such as acrylamide friction reducing compounds, removed to allow the treated water to be an economically viable fracturing water.

International Classification:

US Classification:

Abstract:
Systems and methods have been developed for reclaiming water contaminated with the expected range of contaminants typically associated with produced water, including water contaminated with slick water, methanol and boron. The system includes anaerobically digesting the contaminated water, followed by aerating the water to enhance biological digestion. After aeration, the water is separated using a flotation operation that effectively removes the spent friction reducing agents and allows the treated water to be reclaimed and reused as fracturing water, even though it retains levels of contaminants, including boron and methanol, that would prevent its discharge to the environment under existing standards. The treated water may further be treated by removing the methanol via biological digestion in a bioreactor, separating a majority of the contaminants from the water by reverse osmosis and removing the boron that passes through the reverse osmosis system with a boron-removing ion exchange resin.

Abstract:
Systems and methods have been developed for treating the waste water contaminated with methanol and boron in addition to other contaminants. The systems and methods allow specifically for the removal of the methanol and boron without the addition of significant chemicals to raise the pH. The water is treated by removing the methanol via biological digestion in a bioreactor, separating a majority of the contaminants from the water by reverse osmosis and removing the boron that passes through the reverse osmosis system with a boron-removing ion exchange resin.
