A method for removing sulfates from seawater by immersing a barium adsorbent into produced water to adsorb the barium ions from the produced water. The adsorbent is combined with an acidic solution that pulls the barium ions into the acidic solution. The acidic solution containing barium ions is combined with seawater to precipitate the sulfate as barium sulfate (BaSO).

Methods of recovering barium from produced water to remove sulfates in seawater for oilfield applications

Systems to produce a pond water, pond water compositions, and methods for using pond water compositions are provided. The system may include a rainwater collection system, a water purification system, a condensate collection system, and a mixing tank configured to receive and mix the various water sources to form a pond water. A system for forming a fracturing fluid is provided, wherein the system may include the system for producing a pond water, an additive feed system, and a mixer configured to receive and mix pond water from the mixing tank with one or more additives from the additive feed system to produce a frac fluid. A method of fracturing a well is also provided, which may include producing a pond water, mixing the pond water with one or more additives to form a frac fluid, and pumping the frac fluid downhole to fracture the well.

Pond water (gas plant discharge) based fracturing fluid
