The Nature of ,Flowback, Water. Even if fresh water is used as the base ,fracturing fluid,, what returns to the surface is salty. This is because the water found in association with hydrocarbons has high salinity. Shale oil and gas ,flowback, water salinity typically range from 16,000 parts per million (ppm) to more than 300,000 in some instances.

Results indicate that the ,fracturing fluid, filtration has a great impact on the ,flowback, performance and later gas prodn. Results suggest that increasing the filter cake thickness decreases the gas prodn. peak value, and delays the time showing the peak of gas prodn., and further reduces the cumulative gas prodn.
