... Abstract The combined approach of alkali, surfactant, and polymer (ASP) injection is considered the most promising and enhances oil recovery by reducing residual oil saturation and improving sweep efficiency. However, the performance of ASP flooding is highly sensitive to various factors. Among...

... and heat transfer equations. Chemical flooding is another method applied in the oil and gas industry to improve recovery of heavy oil reservoirs. This involves injecting a composite or non-composite form of chemicals such as surfactant, alkali or polymer into the reservoir. Surfactant and polymer...

... adopted in petroleum production, yielding remarkable outcomes ( Kamalyar, K., Kharrat, R., Nikbakht, M., 2014 ). pH plays a significant role in determining the properties of polymer solutions, particularly affecting the carboxyl groups on the main chain polymerization. The degree of polymer reaction...

The known hazardous effects of most synthetic polymeric corrosion inhibitors have motivated researchers to explore naturally occurring polymers as inhibitors ( Biswas et al., 2017 ). Abstract Preventing and mitigating...

Thermal methods (e.g. Steam flooding) are not feasible as they are difficult for offshore development and are deemed not economical (high SOR). Immiscible gas injection...

... from synthetic bio-degradable polymers. Biopolymers are produced via the use of micro-organisms, and this requires specific nutrients and controlled environmental conditions. This can be through fermentation or by chemical polymerization of monomers. Xanthan is a very common biopolymer that has been...

...Abelmoschus esculentus (Okro) polymer Abstract The use of viscosity enhancer in Polymer flooding decreases mobility and improves sweep efficiency of flood water. However, there is a likelihood of permeability impairment due to the polymer retention onto the rock surface. This leads...
