Abstract Chemical flooding through biopolymers acquires higher attention, especially in acidic reservoirs. This research focuses on the application of chemical for enhanced oil recovery reservoirs, with a particular emphasis modified chitosan. The modification process involved combining chitosan vinyl/silane monomers via emulsion polymerization, followed by an assessment its rheological behavior under simulated reservoir conditions, including salinity, temperature, pressure, and medium pH....

Abstract Recently, the polymer-nanoparticle combination has garnered significant interest in enhanced oil recovery (EOR) due to its promising experimental results. However, previous research was mostly directed at silica, while alumina and zirconia nanoparticles have gotten least consideration. Unlike works, this study aims investigate influence of three NPs: Silica (SiO 2 ), Alumina (Al O 3 Zirconia (ZrO ) on hydrolyzed polyacrylamide (HPAM). To end, nanocomposites were formulated: HPAM-SiO...

Abstract Utilizing xanthan gum, a biodegradable polymer, in enhanced oil recovery (EOR) is imperative wherever there need for innovation production that both cost-effective and environmentally friendly. Xanthan, chosen its natural sourcing, availability, controllability, eco-friendliness, biodegradability, proves resilient against harsh reservoir conditions owing to rigid structure elongated polysaccharide chains. This study investigates two modified gum composites, achieved by grafting with...

Crude oil is the most critical energy source in world, especially for transportation, provision of heat and light as there has not been a sufficient to replace crude broadly integrated, so an urgent need maximize extraction original in-place every reservoir, accelerating development enhanced recovery (EOR) technologies. Polymer flooding by hydrophobically associated polyacrylamides (HAPAM) widely used technique through EOR technology. For successful application these polymers, one should...

Crude oil and other petroleum products are crucial to the global economy today due increasing energy demand approximately (∼1.5%) per year significant remaining after primary secondary recovery (∼45–55% of original in place, OOIP), which accelerates development enhanced (EOR) technologies maximize recovered amount by non-conventional methods as polymer flooding. This review discusses specially flooding techniques their effects on rock wettability alteration.

Due to the increased demand for energy resources these days, especially due Russian-Ukrainian war, focus of major countries is turning strongly towards improving oil production, heavy and extra oil, which represents 40% world reserve. This research focuses on presenting methods maximize productivity currently used such as steam injection, cyclic stimulation, in-situ combustion, steam-assisted gravity drainage, vapor extraction (VAPEX). The also presents future trends improve heavy-oil...

Abstract Lead (Pb +2 ) ions considered a crucial neurotoxic heavy metal result in serious troubles the live biological environment including poisoning, and liver kidney shortage, addition to anemia, hepatitis, encephalopathy, renal syndrome. In current study, biomass of Zea mays (ZMS) was prepared as biosorbent for elimination Pb from aquatic batch mode relevant contact time, pH solution, dose, temperature. The characterized using an SEM microscope coupled with EDX, FTIR, XRD, BET surface...

Abstract The accurate estimation of gas viscosity remains a pivotal concern for petroleum engineers, exerting substantial influence on the modeling efficacy natural operations. Due to their time-consuming and costly nature, experimental measurements are challenging. Data-based machine learning (ML) techniques afford resourceful less exhausting substitution, aiding research industry at that is incredible reach in laboratory. Statistical approaches were used analyze data before applying...

The growing need for energy and the depletion of oil wells necessitate advanced Enhanced Oil Recovery (EOR) techniques, particularly water polymer flooding, which play a crucial role in augmenting hydrocarbon recovery rates. However, flooding high-permeability layers often leads to breakthroughs, reduced sweep efficiency, formation preferential channels, posing significant challenges reservoir management. Conformance control treatments, including use microspheres, offer promising solution by...

Currently, biomolecules flooding in the underground reservoirs acquires sustainable interest owing to their availability and eco-friendly properties. The current study reported chemical displacement by xanthan gum as well xanthan/SiO 2 grafted with vinylsilane derivatives. Chemical characterization evaluated traditional spectroscopic methods. Investigation of fluids response reservoir environment assessed through rheological performance relative shearing rate, ionic strength, thermal...

The viral respiratory disease, severe acute syndrome (SARS), has turned into a global health concern. Till now, there is no drug or vaccine yet been specifically approved for SARS-CoV-2. One of the urgent solutions against recent COVID-19 disease use dietary molecules, which can be found abundantly in functional food. In current study, we have conducted molecular docking approach eighteen molecules belong to subclass anthocyanins, as potential inhibitors main protease and spike glycoprotein...
