A shale oil reservoir is an unconventional oil reservoir obtained by thermoforming, hydrogenation, and thermal dissolution of petroleum accumulations. These processes convert the organic matter in the rock and sand (kerogen) into oil and synthetic gas. The producing oil can be used immediately as fuel or upgraded by adding hydrogen and removing impurities such as sulfur and nitrogen to enter the refinery as a raw material. Refined products can be used in the same applications as refined crude oil products. The lack of water resources in the petroleum industry's operational performance has always been a concern due to water scarcity and the reduction of fertile areas and agricultural processes. Emerging technologies and advancements in unconventional reservoirs would represent a new policy towards energy systems. It is noted that providing sustainable demand of various industries. Today, with declining production from conventional oil and gas reservoirs and increasing demand for fossil fuels, economical oil production from unconventional shales is a significant challenge for the petroleum industry. With the direct injection of hydrogen peroxide into the environment under the coagulation process iron ions can be created, and the process of Fenton can be created in aqueous specimens. The Fenton process is obtained from the combination of two hydrogen peroxide and iron (Fe) ions. It is used in the form of a catalyst that entered the reaction with hydrogen peroxide and increases the production rate of hydroxyl radical formation. Indirect injection of wastewater after treatment processes is to reduce the impairment risks of surface and subsurface pollution, especially in oilfields close to urban and basin areas. To measure the required water needed for different processes, it is necessary to proceed with every step of saving and then make an average to calculate the required freshwater.
