Drilling fluids can be considered complex liquids containing several desired materials. These materials (small additives) are specialty products that serve a specific need, such as controlling the rheological properties of drilling fluid and reducing corrosion for operational both oil gas wells. Additives used to resist called inhibitors. Previous research has shown polymers Carboxymethyl Cellu...

The ~635 Ma Marinoan glaciation is marked by dramatic Earth system perturbations. Deposition of nonmass-dependently (17)O-depleted sulfate (SO4(2-)) in worldwide postglacial sediments is, thus far, unique to this glaciation. It is proposed that an extremely high-pCO2 atmosphere can result in highly (17)O-depleted atmospheric O2, or the Marinoan Oxygen-17 Depletion (MOSD) event. This anomalous (...

The Sirzar Sb prospecting area is located in northeast of Torbat -e- Jam in Khorasan Razavi Province. Mineralization is found both as vein and replacement within carbonate rock (Permian). Two primary stages of mineralization are: 1) galena ± pyrite ± chalcopyrite ± sphalerite ± sulfosalte ± Cu-Sb sulfides, quartz and barite. 2) Stibnite ± pyrite ± sphalerite ± fuloppite, quartz, barite, dolomit...

Abstract Treatment of the filter cake layer after drilling is essential for better cement integrity and to retain original reservoir permeability. Compared water-based cake, oil-based mud removal more sophisticated as oil encloses cake’s particles. Therefore, clean-up requires wettability alteration additives (mutual solvents and/or surfactants) permitting acid/filter reaction. With an appropri...

The Silurian Pelplin Formation is a part of thick, mud-prone distal fill the Caledonian foredeep, which stretches along western margin East European Craton. consists organic carbon-rich mudstones that have recently been target intensive investigations, as they represent potential source shale gas. host numerous calcite concretions containing authigenic pyrite and barite. Mineralogical and petro...

The exploration and mining of Nigerian barite are primarily by artisanal small-scale miners (ASM) whose operations characterized poor productivity. As a result, the quantity quality barites produced do not satisfy nation’s oil sector demands other industries that require mineral. This situation leads to massive importation mineral with negative impact on country’s drive toward increasing contri...

In this study, based on the pure mineral flotation test of barite, effect law microwave barite was investigated by using UV-visible spectrophotometer (L5), solution chemistry calculation and Zeta potential, scanning electron microscope (SEM), other testing methods; at same time, red kinetic analysis carried out to deeply explore mechanism C18H33NaO2 under radiation. Mineral tests show that deio...

We present a characterization of series barite-enriched concrete samples at the atomic scale using neutron-based techniques. In particular, neutron transmission measurements provide macroscopic cross section (also known as removal section) function incident energy in range 1 meV–1 keV. this range, where fewer experimental investigations are available literature, is dominated by scattering event...

Recent developments at synchrotron X-ray beamlines now allow collection of data suitable for structure determination and Rietveld structure refinement at high pressures and temperatures on challenging materials. These include materials, such as dolomite (CaMg(CO3)2) that tends to calcine at high temperatures, and Fe-containing materials, such as the spinel MgFe2O4, which tend to undergo changes...
