Enhanced oil recovery is governed primarily by the role of interfacial tension between crude and water. Interfacial (IFT) oil–water system one vital factors in analysis capillary forces affecting trapped within reservoir rocks. High salinity temperature reservoirs tend to make researchers search for new surfactants lower systems. The current study hopes create a move toward solving above problem through use aromatic ionic liquids (ILs) based on imidazolium as cation various anions such...

Depleted matured reservoirs contain almost two-thirds trapped oil, which remains unrecovered even after primary and secondary oil recovery methods. Chemical enhanced (EOR) methods involve the usage of chemical agents that improve mobility residual by mechanisms involving alteration wettability, viscous fingering reduction within pay zone, interfacial tension (IFT) between interfaces fluids (oil/water) rock, followed reduced capillary forces during flooding. EOR need more research for high...

Chemical treatment of aromatic heavier hydrocarbons are traditionally done by using cyclic nonpolar solvents, such as benzene, xylene, and toluene, which have the capability to dissolve asphaltenes. However, these solvents volatile hazardous hence not advisable use. Alternatively, lighter hydrocarbons, heptane, hexane, etc., show lesser solubility. It is, therefore, crucial that problems require intelligent, cost-effective, innovative solutions. The present work investigates possible...

Proposed mechanism for the enhancement in dissolution of aromatic TBS solvents presence ionic liquids.

The production, processing, and transportation of heavy crude oil (HCO) is difficult because its high viscosity. For practical applications, information on the rheological behavior HCO plays an important role, especially in flow assurance investigations. In this work, six different imidazolium ionic liquids (ILs) were tested for their effects under high-pressure high-temperature conditions. studies carried out at three pressures (0.1, 5, 10 MPa) four experimental temperatures (298.15,...

Enormous production losses have ascended in diverse operational and technical issues due to deposition of heavy crude oil (HCO) various components like tubing, near well bore (skin formation), surface storage tank, pipeline blockage, etc. Existing methods employed for the dissolution HCO are either cumbersome or use organic solvents, which hazardous environment. This study presents findings on enhanced using low waxy (LWC) presence ionic liquid (IL). The ILs is found be compatible with polar...

Abstract The upstream petroleum industry faces operational and technical challenges due to the production of crude oil containing waxes, asphaltenes aromatic compounds also formation gas hydrates resulting in their deposition surface equipments offshore pipelines affecting safer operations, turn huge losses, threatening environment. It is estimated that, all over globe there are more than double times reserves heavy extra-heavy lighter one. In spite this, still low. As world’s demand for...

Heavy crude oil (HCO) production, processing, and transportation forms several practical challenges to the gas industry, due its higher viscosity. Understanding shear rheology of this HCO is highly important tackle production flow assurance. The environmental economic viability conventional methods (thermal or dilution with organic solvents), force industry find an alternative. present study was constructed investigate effect eco-friendly ionic liquids (ILs) on HCO's rheology, at high...
