With increasing global energy demand and the urgency to reduce carbon emissions, carbonated water injection has been proposed tackle these pressing concerns. Carbonated (CWI) in oil formations enhances production support mix issues of security, equity, environmental sustainability. However, CWI reservoirs saline aquifers initiates multiple chemical reactions that promote mineralization, cause formation damage problems, sea-bed subsidence, reservoir compaction, increase pressure requirement, consequently affect practicality for enhanced recovery (EOR) CO2 storage. We therefore extensively reviewed performance EOR storage implications interactions on The analysis covered recent advancements CWI, including its synergy with various techniques where it was identified combining surfactants, polymers, mutual solvents, nanomaterials significantly improved tight (37–65%) compared standalone (35–36%), but potential hybrid technique remains unexplored. Additionally, complex geochemical occur during influencing variables interactions, their consequence were discussed. rigorous revealed existing literature lacks consensus effects pore structure. Geochemical caused a −12% +95% porosity change −96% +417% alteration permeability. Primarily, economic challenges capture transportation costs, preparation, etc., corrosion concerns hinder large-scale implementation CWI. Notwithstanding, findings from life cycle assessment suggested viability highlighted importance adopting innovative achieve dual objectives maximizing minimizing footprints gas industry. Multiple areas require further investigation such as investigating influence condensable incondensable contaminants well integrity safe among others presented.

Summary The change in wettability of limestone reservoirs from oil-wet toward gas-wet can enhance crude oil production during immiscible CO2 injection. Therefore, this research, we investigated the impact alteration to CO2-wet on recovery factor via dissolution fluorine-free, CO2-philic, nonionic surfactants such as C4(PO)6 and C41H83O19 CO2. Based cloudpoint measurements, pressures supercritical ranged between 2,100 psi 2,700 (below reservoir pressure, i.e., 3,000 psi) at temperature, 65°C; these are commensurate with CO2-enhanced (EOR) pressures. Also, reduce CO2-oil interfacial tension (IFT). Moreover, CO2/C4(PO)6 solutions strongly (Θ ~ 20o) intermediate CO2/oil-wet = 95o 110o) conditions. relative permeability curves also confirmed it by changing curvature left decreasing residual saturation both cases solutions. 20.8% 13.1% additional recoveries were achieved 30,000 ppm solution scenarios, respectively, pure injection scenario. These not able make CO2-in-oil foam; therefore, perhaps IFT reduction dominant mechanisms EOR induced CO2, instead mobility control. Consequently, oxygenated, (such C41H83O19) concentration be a well-qualified candidate for altering CO2-oil-wet

The carbon dioxide (CO2) based enhanced oil recovery methods (EORs) are considered among the promising techniques for increasing factor from mature reservoirs and reducing amount of CO2 emission in atmosphere. Determining minimum miscibility pressure (MMP) – systems is a crucial step successfully implementing EOR processes. Therefore, various approaches have been proposed determining this key parameter. However, laboratory tests expensive time-consuming, while most available correlations present moderate accuracy. To address these shortcomings, studies applied artificial intelligence (AI) to model MMP systems. In study, we reviewed published works predicting using AI-based models. Our analyses revealed robustness modeling MMP. context, it was noticed that more than 70 paradigms utilized estimating Among applications, hybrid schemes combining machine learning nature-inspired algorithms (ML-NIA) take top spot, accounting 27% applications.

Summary In this study, the ability of dilute concentrations toluene to act as a CO2-soluble asphaltene stabilization agent capable inhibiting precipitation during immiscible CO2 injection was assessed. Phase behavior results indicated that 1,000 20,000 ppm could readily dissolve in at cloudpoint pressures are well below formation pressure and typical minimum miscibility (MMP) values gas-based enhanced oil recovery (EOR). Single-phase solutions modified gas (CO2/toluene) were then combined with asphaltenic oils swelling phase tests demonstrate presence increased amount dissolved into reservoir crude specified temperature pressure. However, diminished, apparently because effect solvent strength more significant than (an antisolvent) entered oil-rich phase. During CO2/toluene solution cores initially saturated brine, compared pure CO2, deposition declined mixtures for volatile intermediate from 3.7 wt% 0.7 5.9 1.7 wt%, respectively. Based on particle-size analysis, can stabilize particles simultaneously reduce aggregation effectively CO2.

Carbonated water (CW) injection refers to a development method that involves dissolving CO2 in under specific temperatures and pressures, followed by its into reservoirs for oil recovery. This technique can simultaneously enhance recovery facilitate storage, although effectiveness requires further improvement.
