Organoclay cost effectively removes oil from produced water
- Biomin Inc., Ferndale, MI (United States)
An organoclay-based method can economically treat produced water that is reinjected into formations. Organoclay refers to bentonitic clay platelets modified with quaternary amine. Operators can dispose of the spent organoclay in landfills, as long as it is nonhazardous, or ship it to asphalt producers or fuel blenders. Activated carbon is regenerated or incinerated if it is hazardous. Operators reinject produced water into formations either for water disposal or waterflooding to recover additional oil. In either case to minimize formation plugging, it is important to remove oil and other materials from the water. If removing metals, the media must be designed carefully for each situation. The paper discusses disposal regulations, on-site treatment train, and water disposal economics.
