In this work, polymeric materials designed for enhanced oil recovery (EOR) were evaluated their intended application. Properties including viscosity, flow through porous media (resistance factor and residual resistance factor), heavy displacement (incremental recovery) assessed terpolymers of 2-acrylamido-2-methylpropane sulphonic acid (AMPS), acrylamide (AAm), acrylic (AAc). The same propertie...

Characterization of fluid–rock interactions is essential for a broad range subsurface applications such as understanding fluid flow in porous medium and enhanced oil recovery predictions. Enhanced (EOR) crucial gas production operations, it entails injecting fluids into the reservoir to enhance productivity. When are injected, occur between injected rock/fluids; outcomes critically impact assoc...

Enhanced Oil Recovery (EOR) is known to effectively improve oil recovery by producing the residual saturation in a reservoir. Many chemicals for injected fluid EOR are synthetic and harmful environment. Aims: This study aims characterize newly developed green solution consisting of Sodium Lignosulfonate (SLS) Low Transition Temperature Mixture (LTTM) injection agent. Methodology Results: The co...

One of the major challenges in petroleum industry is producing residual oil from underground. One of the major techniques for enhancing oil recovery (EOR) is using gas injection. However, gas has poor volumetric sweep efficiency, this is attributed to its high mobility which considers to be higher compared with oil and water mobility. Several techniques are proposed and applied for reducing gas...

The minimum miscibility pressure (MMP) is one of the crucial and substantial parameters in the gas injection projects for enhanced oil recovery (EOR). This parameter indicates the minimum pressure at constant temperature and composition conditions for reaching 100 percent of the oil production recovery which leads to a huge economic income. Therefore, an inaccurate prediction of the MMP may lea...

Emulsification is one of the important processes in chemical flooding to mobilize residual oil wells following secondary recovery. Oil displacement efficiency enhanced and volumetric sweep increased by engineering interactions supporting chemicals used with geological formations present wells. Polymers surfactants are often applied recovery (EOR) as emulsification displacement. However, polymer...

Abstract Gum arabic (GA) capacity as an enhanced oil recovery (EOR) agent is studied and compared to the commonly applied xanthan gum (XG). FTIR TGA characterisation of these two polyelectrolytes a rheology study by viscosity measurement was conducted on their polymeric nano-polymeric solution at varying concentrations polymers nanoparticles (NP). Coreflooding experiments were based sequence wa...

To extract all the oil from a well, petroleum engineers pump hot reactive chemicals into the well. These Enhanced Oil Recovery (EOR) processes need to be thoroughly monitored, since the injected fluids can seep out of the production oil wells and, if unchecked, eventually pollute sources of drinking water. There is a need to measure the corresponding effects. One way to measure these undergroun...

Rhamnolipids mainly are produced by Pseudomonas aeruginosa and another microorganism that have been found to have good surface activity. Rhamnolipids are used in various application areas, including environmental, health, food, cosmetic, oil industries, pharmaceuticals and environmental bio remediation particularly in enhanced oil recovery (EOR) and cleaning of oil spills. Many kinds of bio sur...

Chemicals are a pivotal part of many operations for the oil and gas industry. The purpose chemical application in subsurface reservoir is to decrease mobility ratio between displaced fluid displacing one or increase capillary number. These have been favorable mechanisms Enhanced Oil Recovery (EOR). Recently, it became mainstay with EOR researchers looking effective efficient materials that can ...
