Abstract The ability to transport nanoparticles through porous media has interesting engineering applications, notably in reservoir capacity exploration and soil remediation. A series of core-flooding experiments were conducted for quantitative analysis functionalized TiO 2 various including calcite, dolomite, silica, limestone rocks. adsorption surfactants on the rock surface nanoparticle rete...

Wettability alteration would play a significant role in the hydrocarbon displacement as it can improve oil recovery factor both conventional and unconventional reservoirs. Therefore, accurate prediction of this parameter be importance sweep efficiencies. In paper, we aimed to experimentally investigate wettability changes presence nonionic natural surfactant (Cedar) for different carbonate mine...

the silica gel waste (sgw), after its collection from a local factory (kolkata, india) was modified with cationic surfactant and was utilized as an adsorbing media for the removal of 2,4- dichlorophenoxyacetic acid (2,4-d) from agricultural runoff of a tea garden. characterization of base adsorbent and modified adsorbent was carried out. the efficacy of the adsorbent was evaluated through both ...

Replacement dolomite in the Latemar carbonate buildup, northern Italy, formed when limestone was infiltrated by and reacted with Mg-rich fluid. It occurs in discrete bodies in sharp contact with unreacted limestone. The dolomite developed in a nearly orthogonal lattice of vertical columns (replacement of limestone breccia pipes) and sheets (replacement along fractures and limestone-dike contact...

this study examines the effects of change in the concentrations of monovalent and divalent ions in the polymer-contained surfactant solution on the macroscopic behavior of viscous-modified surfactant waterflooding in heavy oil reservoirs. salts that are used in this set of floods were sodium chloride, magnesium chloride, and calcium chloride. the results indicate that four different ranges of s...

a simple, highly sensitive, accurate and selective method was presented for determination of trace amounts of cu (ii) in water samples. the stability of an n, n´ -disalicylideneethylenediamine modified nano geraphene especially in concentrated hydrochloric acid was studied which used as a recycling and pre-concentration reagent for further uses of n, n´-disalicylideneethylenediamine modified na...

Empirical Calibration for Dolomite Stoichiometry Calculation: Application on Triassic Muschelkalk-Lettenkohle Carbonates (French Jura) — This study concerns an approach for dolomite quantification and stoichiometry calculation by using X-ray diffractometry coupled with cell and Rietveld refinements and equipped with a newly substantial database of dolomite composition. A greater accuracy and pr...
