Sulphate reducing prokaryotes (SRP) cause hydrogen sulphide (H2S) generation in some waterflooded hydrocarbon reservoirs that is known as microbial reservoir souring or biosouring. The H2S generated in-situ by SRP toxic and corrosive adversely affects the quality, production, economy of oil fields together with negative environmental impacts. Various chemical, biological, methods have been implemented to control such reactions past few decades but still they are not fully controllable. This...

In the oil and gas industry, it is very important to recover maximum amount of extracted from reservoirs. Many methods are employed in extraction process Enhanced Oil Recovery (EOR) obtain recovery, but unfortunately, only up 70% can be recovered One most new techniques EOR use nanotechnology during recovery process. Without mathematical analysis, difficult perform experiments oil, as experimental setup costly. Hence, essential study physical properties reservoir its flow behaviour get...

In reservoir conformance control, polymer gels and foams are majorly used; however, they have drawbacks such as inducing formation damage, having weaker shear resistance, requiring a higher pumping rate, limited penetration depth. Emulsions potential alternative that can address these issues, but not widely used. Current surfactant-based emulsions require high emulsifier concentrations for stability often rely on multiple additives to various factors, which makes the surfactant synthesis...
