Copper-based silica is a promising catalyst for several reaction pathways for CO2 conversion to hydrocarbons. The activity of this catalyst in terms of conversion and product selectivity is affected by CO2 adsorption, ...

Cuttings removal out of the wellbore represents a real barrier for successful drilling operations. The performance of hole cleaning is determined by several factors. The current article provides a theoretical study of the ...

In this study, the influence of a hybrid coagulation/flocculation process on the electrokinetic of highly stable bentonite suspension has been examined. Choline chloride (ChCl) based natural deep eutectic solvent (NADES) ...

Calcium carbonate scale forms in production and injection wells, precipitating upon pressure and temperature changes, incompatible water mixing, and dehydration. Production shutdown is one of the most dramatic consequences ...

Pyrite scale formation is a critical problem in the hydrocarbon production industry; it affects the flow of hydrocarbon within the reservoir and the surface facilities. Treatments with inorganic acids, such as HCl, results ...

In this work, the interaction of methane and carbon dioxide on α-quartz with surface 001, with a siloxane termination (dense) surface was investigated by means of Ab-Initio Molecular Dynamics. Different temperatures were ...

The potential crosslinking of three types of nitrogen-containing functionalized silica (TAAcONa, guanidine, and triamine) with polyacrylamide (PAM) has been investigated. Only triamine silica was able to crosslink with ...

Scale prevention is a long-term challenge. It is essential for ensuring the optimum utilization of oil and gas wells and minimizing economic losses due to disruptions in the hydrocarbon flow. Among the commonly precipitated ...

The current study applied the forward osmosis (FO) based osmotic concentration (OC) process at the pilot-scale for concentrating synthetic feed solution (FS). The process water (PW) salinity represents effluents from the ...

Iron sulfide scale causes major losses in both upstream and downstream sectors of the hydrocarbon industry. Pyrite is one of the most-difficult forms of iron sulfide scale from a removal point of view. Inorganic acids such ...
