Produced water is made up of what is under the layer of oil in a reservoir, which occurs naturally, and the water injected into crevices through fracking. When used to increase the production of oil or natural gas, the naturally-occurring and injection water combine with the oil for the total fluid obtained, and the water portion must be managed. This means treatment before it’s recycled and placed back into the environment.
HYDRASEP uses processes in which the water from fracking is treated and returned to ground or offshore wells. Here’s what happens: this water is composed of both organic and inorganic substances. Some of these substances are dissolved in the fracking water, and others are suspended in it. What happens is the water extracted from the well could be a different composition from the water surrounding it, and returning it could upset the environment. Wells can be on land or offshore. If offshore, it could be deep or shallow sea. All these factors must be considered when treating the produced water and returning it. For example, if the water is from the ocean, it will be too salty to return on land.
HYDRASEP treats the water produced from fracking and injects it back into the environment after it’s treated to encourage better flow of oil. This accomplishes a few things: it filters the water through rock and sand, which removes the tiniest solid particles, and allows for better oil and gas extraction.
