Enhanced drilling waste-water treatment through magnetic nano-composite coagulant application: A central composite design study.

A magnetic nano-composite coagulant has been designed, originally applied in a specific industrial waste-water treatment, and statistically investigated using Central Composite Design (CCD). The generated polynomial models were utilized to achieve a comprehensive understanding of the impact of each ingredient of PolyAluminum Chloride (PAC), PolyAcrylAmide (PAM), and Iron (III) oxide magnetic nano particles (MNP) regarding optimum limits and conditions. The concentration of each of those components has been considered as the main effective factors, which are found to be significantly correlated, affecting the Total Dissolved Solid (TDS) removal (%), the Total Suspended Solid (TSS) removal (%), and the Turbidity Reduction Rate (TRR) NTU/min.

Mechanistic understanding of asphaltene precipitation and oil recovery enhancement using SiO and CaCO nano-inhibitors.

Asphaltene precipitation in oil reservoirs, well equipment, and pipelines reduces production, causing pore blockage, wettability changes, and decreased efficiency. Asphaltenes, with their unique chemical structure, self-assemble via acid-base interactions and hydrogen bonding. Nano-inhibitors prevent asphaltene aggregation at the nanoscale under reservoir conditions.

Assessment of heavy oil recovery mechanisms using in-situ synthesized CeO nanoparticles.

This project investigated the impact of low-temperature, in-situ synthesis of cerium oxide (CeO) nanoparticles on various aspects of oil recovery mechanisms, including changes in oil viscosity, alterations in reservoir rock wettability, and the resulting oil recovery factor. The nanoparticles were synthesized using a microemulsion procedure and subjected to various characterization analyses. Subsequently, these synthesized nanoparticles were prepared and injected into a glass micromodel, both in-situ and ex-situ, to evaluate their effectiveness.

Utilization of synthesized silane-based silica Janus nanoparticles to improve foam stability applicable in oil production: static study.

This study investigated the effect of silane-based silica (SiO) Janus nanoparticles (JNPs) on stabilizing the foam generated by different types of gases. Two types of SiO JNPs were synthesized through surface modification using HMDS and APTS silane compounds. Static analyses were conducted to examine the impact of different concentrations of the synthesized nanoparticles in various atmospheres (air, CO, and CH) on surface tension, foamability, and foam stability.
