Affordable High Salinity Frac Water
Marcellus Shale Frac Water Treatment Options
Effective water administration is a vital a half of Marcellus Shale development. Hydraulic fracturing, the method of using high pressure water with sand and chemical additives to crack the shale and drive the fuel to the surface, makes use of three to 5 million gallons of water per well. high salinity frac water of the injected water stays within the Marcellus formation, with less than 15% on average returning to the Earth's surface. The design and development of the nicely isolates the fluids within the nicely whereas proper dealing with of the materials on the well pad prevents spills and groundwater contamination. However, the continued debate over the impression that this water and the additives that are used to interrupt up the shale have on our water assets continues to be essential.

The Pennsylvania Department of Environmental Protection lately began implementing new rules regarding the therapy of whole dissolved solids - the minerals, salts and metals which would possibly be dissolved in a given quantity of water - in an effort to lower the dangers of those materials entering the Commonwealth's waters. The matter has raised questions concerning the therapy, value and disposal of the Marcellus Shale flowback, that are affected by variables similar to volume and water high quality.

Marcellus Shale builders are analyzing totally different disposal and therapy choices to discover out the professionals and cons of every and find essentially the most cost-effective and efficient scenario of handling frac flowback. high salinity frac water carried out in 2010 revealed the next options:


Hauling the flowback outside of Pennsylvania for treatment in a nearby state is likely considered one of the first options. However, high expenses may make this much less engaging for large operations.

Underground injection is an choice but cost and availability of wells in Pennsylvania are just some of the disadvantages.

On-site treatment may work for some however it's going to doubtless require hauling to a crystallization facility to scale back the remaining brine volume. Many of today's remedy applied sciences are not able to deal with the salinity concentrations and can therefore drive additional hauling to sites.

Off-site therapy for zero liquid discharge is an option, but there are a selection of factors that can impression the viability of this option.

Another alternative is pumping to a close-by centralized remedy facility which will result in long pipelines and centralized pumping services.

Dilution and reuse at the well was found to be probably the most cost-effective possibility however nonetheless requires some remedy to reduce back friction. New points and other regulatory limitations might arise if reuse is used as a ultimate technique.
