TECHNOLOGY FOCUS - ENVIRONMENT - Preferred Method: The servicing (M1) of the wellbore further involves: adjusting the Zeta potential of the fluid to adjust the viscosity; the fluid has a first pH, and further the Zeta potential of the fluid is adjusted by adjusting the first pH to a second pH; adjusting the Zeta potential of the fluid by adding a surfactant to the fluid; adding an ester to the fluid to adjust the viscosity; and fracturing the wellbore with the well servicing fluid.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The concentration of nanoparticles (A1) is 2-20 wt.%, based on the total weight of the well servicing fluid (C1). The nanoparticles comprise boehmite more than 50 wt.%. The nanoparticles have a crystallized size of less than or equal to 100 nm in diameter. The fluid (C1) has a Zeta potential of 0-50; and a pH of 2-14. The well servicing fluid further comprises at least one compound chosen from pH adjusters, surfactants and esters. The pH adjuster is chosen from sodium hydroxide (NaOH), potassium hydroxide (KOH), calcium hydroxide (Ca(OH)2), sodium bicarbonate, potassium carbonate, and sodium carbonate. The fluid further comprises a proppant. The continuous phase is a liquid chosen from fresh water, brine, and produced water. The concentration of salt in the brine is at least 0.5 wt.%. The fluid is formulated with at least one breaker.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The fluid (C1) is formulated with at least one additional compound chosen from water wetting surfactants, non-emulsifiers, additional viscosifying agents, surfactants, clay stabilization additives, scale dissolvers, biopolymer degradation additives, fluid loss control additives, and high temperature stabilizers.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The ester is an ester of polycarboxylic acid. EXAMPLE - A wellbore servicing composition comprising: water; Catapal 200 Alumina (RTM: alumina) (5%); and caustic soda (25%) (to pH 9.5); was prepared by adding alumina to water, and adjusting pH to 9.5.
