Polymers play a crucial role in enhanced oil recovery (EOR) by increasing the viscosity of injection fluids and enhancing displacement. The widely used polymer, partially hydrolyzed polyacrylamide (HPAM), faces performance degradation high-salinity high-temperature environments. This study explores galactomannan from Stryphnodendron polyphyllum seeds as an alternative viscosifying agent for EOR fluids. An extraction process Barbatimão Verdadeiro was developed, yielding 23.3% m/m. biopolymer characterized using Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), thermogravimetric analysis (TGA), size exclusion chromatography (SEC). Rheological behavior tested brines different salinities, injectivity/filterability tests were performed following API RP 63:1990 standards. obtained exhibited mannose-to-galactose ratio 1.32. showed pseudoplastic behavior, with viscosities 38 cP brine solutions at 7.37 s−1 60 °C. Filterability demonstrated satisfactory injectivity factors 1.09 (8 µm) 0.67 (1.2 µm). Compared to HPAM, superior retention conditions, where HPAM dropped 6 cP. extracted is promising applications, offering under harsh conditions compared traditional HPAM. Its resilience high salinity temperature makes it viable pre-salt offshore fields, contributing more sustainable efficient recovery.

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 sealing zones enhancing efficiency. This study focuses on application fluorescent microspheres based polyacrylamide, is extensively employed sector as an displacement agent. Fluorescent polymers called Poly 400, 200, 600, incorporating cationic methacrylamide monomers, were synthesized through copolymerization create amphiphilic with enhanced stability functionality. These evaluated tests using quarter-five-spot model transparent quartz glass under UV light, allowing instantaneous measurement observation fluorescence intensity. At conditions, experiments confirm that incremental after 13.1%, 9.1%, 6.1% OOIP respectively. findings showed could efficiently target layers, adapt varying pore throat sizes, improve plugging rate thereby optimizing recovery. A subsequent simulation CMG simulator provided further insights into efficacy these EOR agents, revealing their potential enhance efficiency Simulation results saturation decreased from 68% (initial) 13.5%, 16.1%, 18.3% 600 work highlights valuable tool applications, offering advancements management optimization.

Carbon dioxide (CO2) contributes to erratic climate changes as a greenhouse gas in the atmosphere, highlighting need for effective carbon capture, storage, and conversion strategies. This study introduces green solvent approach using protic poly(ionic liquids) (PPILs) CO2 chemisorption improve enhanced oil recovery (EOR) methods through gas/polymer flooding. The PPILs were synthesized by copolymerizing quaternized triethanolammonium 2-acrylamido-2-methylpropanesulfonate (QAMPS) with an equimolar amount of triethanol ammonium acrylate (QAA) via radical polymerization, resulting QAMPS/QAA copolymers. Similarly, QAMPS was copolymerized amounts 2-hydroxyethyl methacrylate (HEMA) or N-vinylpyrrolidone (VP) produce QAMPS/HEMA QAMPS/VP PILs. examined chemical structure, thermal degradation stability, transitions. QAMPS/QAA, QAMPS/HEMA, obtained at initial temperatures 210, 275, 150 °C, respectively. rheological properties these assess their effectiveness solubilization, absorption, desorption both atmospheric high pressures (800 psi) formation water potential application EOR flooding strategies examined. Additionally, research explores dynamics uptake PILs ensuing alterations viscosity, which are crucial enhancing performance success processes. Flooding on 1D sandstone model revealed rates 38.9% 35.3% QAMPS/VP, 35% relevant residual saturation (%Sor).

ABSTRACT Biopolymers are molecules widely used in many industries because they biodegradable and have a natural origin. Therefore, can be obtained from renewable resources organisms such as animals, plants, or microorganisms. Among the best‐known biopolymers, xanthan gum is an anionic biopolymer composed of glucose, mannose, glucuronic acid, pyruvic acetyl groups. It by fermentation with bacteria genus Xanthomonas , has good physicochemical properties, it biocompatible human cells. However, disadvantages very susceptible to microbial contamination. various physical, chemical, enzymatic modification methods been developed improve its biological properties. Modifications backbone chains made possible create derivatives new uses, drug delivery systems improving absorption pharmaceutical industry enhance efficacy several treatments therapeutic processes, promote cell proliferation for tissue engineering biomedical applications when hydrogels films. They also food products, cosmetics, recover oil water ground, treat wastewater, granting soil conditions plant vegetables growth. Hence, important know develop impart properties obtain novel gum.

This paper aims to study the impact of AMPS on structure and viscoelastic behavior hydrogels. A copolymer acrylamide 2-acrylamido-2-methylpropane sulfonic acid (AMPSA), N,N-methylene bisacrylamide (MBA), aluminum persulfate (APS) were synthesized using free radical polymerization. The percentages AMPSA 10, 30, 50, 70%. Polyethyleneimine (PEI), was added as a second crosslinker. hydrogel's equilibrium swelling microscopic examined through SEM ESEM tests. Rheology, TGA, DSC, coreflooding experiments also conducted scrutinize performance under stress strain, thermal stability, efficacy in reducing water permeability managing water, respectively. optimal sample exhibited an 22 maintained structural strength its swollen pressurized states, confirming existence porous associated cages. Zener model corroborated solid-like hydrogel, while sweep frequency test revealed three-dimensional structure, elastic state, strength. hydrogel showed impressive capacity retain even when subjected 1%, 100%, 1000% strains. TGA DSC tests attested stability ensuring at temperatures exceeding 120 °C. Finally, results demonstrated significant reduction from 0.112 0.005 D before after injecting resulting almost 70% decrease cut. Consequently, dual-crosslinked with ratio 7:3, AM/AMPSA, emerged most promising candidate for injection sandstone reservoirs high temperatures.
