The formation of ,scale, deposits upon tubing, casing, perforations, and even on the formation face itself, can severely constrict ,fluid, flow and reduce the production rate ,of oil, and gas wells. In addition to lost production, a considerable portion of the workover budget is expended in efforts to remove these deposits and prevent their recurrence.

Evonik Oil Additives has developed a novel type of paraffin inhibitor that is dispersible in water. This solution allows the product to be fully compatible with most frac fluids. By incorporating a paraffin inhibitor, wax deposition during the frac process can be mitigated, potentially enhancing oil recovery from liquids-rich shale reservoirs.

This mixture, called fracturing fluid, creates fissures in the shale increasing its permeability and gas recovery. The mixture of the injected fracturing fluid together with the connate water of the formation, which returns to the surface within few weeks after pressure being released, is called flowback water (Olmstead et al., 2013).
