out and pipeline cleaning known aluminum soaps as indicated above can be used the liquid hydrocarbon can be diesel kerosene or other aliphatic hydrocarbons unlike in water base fluids where the majority of conventional hydrocarbon surfactants can be used as a foaming agent the hydrocarbon foaming agents which are preferred for use in accordance with the presence invention are certain fluorinated surfactants or silicone base hydrocarbon foaming agents different gases including air nitrogen carbon oxide natural gas propane and mixtures thereof can be used after operations completed the fluids flow out the wells and can be reused to adequately store the flowback fluid the fluid has to be defoamed immediately after the operations in the present invention we have found that conventional defoamer such as emulsified silicone oil or 2 ethylhexanol is ineffective in defoaming the fluid in the present invention we have found that the fluids can be defoamed by methanol or ethanol at approperate concentration it notes that the increased viscosity of the gelled fluid enhances the stability of the foam on the other hand high viscosity of the fluid may impede formation of sufficient amount of foam the requisite balance between the fluid viscosity and foamability can be determined by simple lab tests the following example is presented to illustrate the preparation and the properties of the fluids and should not be construed to limit the scope of the invention the foam fluid properties.
