... hydrothermal reaction and finally form as nanocomposites. The elemental carbon content, zeta potential and particle size distribution of the nanocomposites could be adjusted according to the reaction conditions. After thermal aging at 220 °C and 240 °C, addition of nanocomposites can improve the rheological...

... spontaneous imbibition tests, core flood experiments, and zeta potential data. Selected HNAF formulations, such as SiO 2 -Acid (HNAF1), Al 2 O 3 -Acid (HNAF2) and ZnO -Acid (HNAF3), produced a significant IFT reduction under HPHT conditions from 18 dyne/cm (formation water and oil) to 3.14 dyne/cm...

... solution. The chemical system increases the attraction between particles (zeta potential) without imposing damage, therefore trapping formation fines and sands to maximize sand-free flow rates and increase production. It is suited for use across a wide range of permeabilities, which makes it feasible...

... into the effect of nanoparticle additives on temperature related rheology of VES fluids has been provided. This understanding is crucial for the optimization of a VES fracturing fluid based on the well-to-well changes in temperatures. hydraulic fracturing wormlike micelle zeta potential fracturing...

... to solve these problems, a completely cationic drilling fluid system with excellent inhibition and stability in ultra-deep wells has been researched. The completely cationic drilling fluid system, characterized by a zero zeta potential differential between the fluid system and the formation to which...

... in the injected water to identify the optimum salinity. Coreflood experiments of waterflooding and cation exchange tests were conducted to investigate the impact of cations on oil recovery, and understand the rock/brine interactions. In addition, zeta potential at oil/brine and rock/brine interfaces were measured...

... Abstract This paper describes lab studies and field results on how a new Zeta Potential Altering System (ZPAS), utilized in fracturing treating fluids, improves gas rate production. Lab and field results show ZPAS minimizes proppant flow back and coal fines migration, enhances fluid load...
