Hydrocarbon gellants

Foam fluids are essentially two-phase fluids that consist of an inner phase and an outer phase. The inner phase is generally gaseous, usually N2 however, it can be liquid or dense vapor as is the case when C02 is used. The external phase is primarily composed of a saline—water mixture with either a surfactant or gellant depending upon the viscosity and stability requirements. Other external fluids commonly used are either hydrochloric add or alcohol—water mixtures. Diesel fuel, reformates, or other hydrocarbon-based solvents can also be used as external-phase fluids but require N2 as the energizer. Carbon dioxide and hydrocarbons produce a single-phased fluid, because C02 is very soluble in hydrocarbon liquids.

Mixed DAP esters based on this chemistry are important as gellants for enhanced oil recovery [71-73], Phosphoric anhydride is reacted with triethyl phosphate in a hydrocarbon solvent and the slurry heated to 100°C for 1 h. A blend of octanol and decanol is then added in a second step to the intermediate mixture and the reaction is continued for 2 h at 130°C [73], The resulting product is blended with diesel oil and cross-linked to a viscous pumpable gel with aluminum isopropoxide or trivalent metal. The product, by reaction of phosphoric anhydride directly with a blend of ethanol, octanol, and decanol, does not perform because of a much higher MAP content [71], A dialkyl content (mixed ethyl alkyl monobasic ester) of 75-85 mol% is preferred and advantages are reported for use of a hexanol-decanol blend in the finishing step [71],...
