Frac tanks are commonly used across the oil and gas industry during hydraulic fracturing, flowback, and produced water management. In the fracking process, they store large volumes of water, chemicals, and proppants used to create the fracturing fluid, ensuring a continuous supply to the well site. According to a report by Ceres, around 5 to 6 million gallons or fluid is used on the average frac job. After fracking, when flowback fluid returns to the surface, frac tanks temporarily store the mixture, which often contains chemicals, sand, and hydrocarbons, until it can be processed or disposed of. Throughout the life of the well, they also can serve as produced water storage tanks—naturally occurring water from underground formations—before treatment or disposal. The benefits of using frac tanks include their portability, high capacity, and versatility for handling various liquids involved in oil and gas operations.
