摘要： A system an oil-water separation system including a vessel for receiving an oil-water mixture and passing a treated water having a lower concentration of oil than the oil-water mixture. The system further includes a first overflow baffle for directing the oil-water mixture fluid flow over the first overflow baffle, and a first underflow baffle positioned downstream along a fluid flow pathway of the first overflow baffle for directing the oil-water mixture fluid flow under the first underflow baffle, and a second overflow baffle positioned downstream along the fluid flow pathway of the first underflow baffle having a mesh with a plurality of perforations which directs fluid flow over the second overflow baffle and through the plurality of perforations. The second overflow baffle permits a water portion of the oil-water mixture to traverse through the mesh and an oil portion of the oil-water mixture to traverse over the mesh.

摘要： The disclosure relates to superhydrophobic membranes and methods of making and using such membranes. Polydimethylsiloxane (PDMS) substrate is formed on sandpaper such that the PDMS substrate has a surface texture replicating the opposite impression of the sandpaper texture. Separately, a PVDF solution is prepared and disposed on the PDMS substrate. The PVDF substrate and liquid film combination are transferred to a solution of deionized water mixed with 2-propanol to form a PVDF film on the PDMS substrate. The PVDF film-PDMS substrate is transferred to a second DI water bath, after which the PVDF film is detached from the PDMS substrate. The PVDF film is then washed and dried, to yield a superhydrophobic PVDF membrane having the texture of sandpaper.

摘要： A system and method for generating water concentrated in calcium bromide from produced water, to provide for drilling fluid having the calcium bromide. The technique includes flowing the produced water through a bed of ion-exchange resin to sorb bromide ions from the produced water onto the ion-exchange resin, and then regenerating the ion-exchange resin to desorb the bromide ions for combination with calcium ions to acquire an aqueous solution with calcium and bromide.

摘要： A system and method for generating base water and precipitate, including combining produced water with seawater to precipitate barium sulfate from barium in the produced water and from sulfate in the seawater, and separating the precipitate to give the base water and the precipitate. The base water may have less than a specified amount of sulfate and be utilized for hydraulic fracturing fluid. The precipitate may give a weighting agent for drilling.

摘要： A method is provided herein for using produced water (PW), for example, for use in a fracturing fluid. The method includes performing ultrafiltration on the PW to form filtered PW, filtering seawater (SW) to form filtered SW, and blending the filtered PW with the filtered SW to form an aqueous blend.
