The ,amount, of PW varies from well to well as well as the age of reservoir. The volume of PW typically increases with the age of reservoir and in certain cases it can reach up to 98% of the ,total fluid, volume (Igunnu and Chen, 2012;Alzahrani and Mohammad, 2014). However, it is generally recognized as 1:3 ratio for oil & water for most of the oil well.

Hydraulic ,fracturing, is the main method for tight gas reservoir development because of its extremely low permeability and porosity. During hydraulic ,fracturing,, high hydraulic ,fracturing fluid, (HFF) that invaded the zone near the fracture face may reduce gas relative permeability significantly and impede gas production.
