Abstract
A fracturing fluid base oil is formed as a blend of diesel and stabilized light condensates consisting essentially of hydrocarbons in the range of C6-C24, preferably consisting essentially of C7-C9 and C10-C16 hydrocarbons. The hydrocarbons may be non-, partially or fully hydrotreated and may comprise n-alkanes 10 to 80 % by wt, preferably <40% by wt, isoalkanes 10-80% by wt, preferably >40% by wt, and aromatics no greater than 30% by wt, preferably <20% by wt. The blended fluid has a preferred viscosity less than 1.25 cSt at 40°C and a pour paint less than -30°C, preferably less than -40°C. The density should be less than 840 kg/m3 and preferably less than 810 kg/m3. The Reid vapor Pressure should be lass than 7.5 kPa, preferably less than 3 kPa. The flash point should be greater than 10°C, preferably greater than 15°C.
