This study explores the effects of silica flour and potassium chloride on rheological properties high temperature pressure gas wells. Seven different materials were used as additives which includes: fresh water, dyckerhoff, flour, antifoam, extender, fluid loss, dispersant, retarder, anti-settling agent, control dry viscosifier, accelerator. Four recipes prepared using these in mixtures. Recipe...

Silica residue is the main product of the alteration of a rhyolitic, tuff-rich, volcanic substrate by acid sulfate condensate formed, in a major steam field at Tikitere, near Rotorua. Here steam and accompanying H2S discharge in an area characterized by large standing pools of acid water and mud pots. As in silica sinters, that precipitate from hot, near-neutral, alkali chloride waters, the fir...

There are increasing research endeavours on the application of nanotechnology in construction industry and lightweight composites. In this study, influence different percentage (1%, 2%, 3% by weight cement) colloidal nano-silica particles mechanical, thermal, durability properties cementitious composites was studied through measurement compressive strength, flexural response, micro-hardness mea...

Among various parameters that influence the formation of polyelectrolyte complexes and multilayers, special emphasis should be placed on ion-specific solvent effects. In our study, we systematically examined above-mentioned effects poly(diallyldimethylammonium chloride) (PDADMACl)-sodium poly(4-styrenesulfonate) (NaPSS) complexation in solution at surface by means dynamic light scattering, elli...
