Enhanced oil recovery (EOR) has long proven to be a good method to mobilize the residual oil that is by passed and capillary trapped by secondary recovery methods. Chemical EOR methods enhance the microscopic and macroscopic efficiency, and ultimately the... see more

In this work, chemical precipitation-ultrafiltration (UF) was applied for waste brine regeneration from a steam flooding plant at Duri Field, Chevron. A mixture of sodium hydroxide and sodium carbonate solution was used as chemical agent. A polypropylene ... see more

Organic residues often exhibit different physico-chemical properties and affect the soil ecosystem in different ways. Hence, the study of their impact on soil is essential to benefit from their potential as amendments and to avoid adverse environmental ef... see more

AbstractThis article presents findings from a study carried out in Keko Machungwa informal settlement in Dar es Salaam under the auspices of the Disaster Management Training Centre of Ardhi University, Tanzania. The settlement has experienced frequent ... see more

Polymer-surfactant flooding which is an effective technology to enhance oil recovery, has been widely applied in Shengli oil field of China. At the stage of subsequent water flooding after polymer-surfactant injection, the injectivity and productivity of ... see more

The tertiary oil recovery methods like alkaline, surfactant and polymer (ASP) flooding are very perspective in order to achieve the synergetic effect out of the different impacts which are caused by these chemicals, which affect oil and water filtration i... see more

Several researchers have proposed that mobility control mechanisms can positively contribute to oil recovery in the case of emulsions generated in Enhanced-Oil Recovery (EOR) operations. Chemical EOR techniques that use alkaline components or/and surfacta... see more

Environmental issues linked to climate change and global warming have been at the center stage of discussion all over the world. This is due to their magnitude and a broader scope of consequences. The catastrophic effects of greenhouse gases (GHGs) such a... see more

The article analyzes the consequences of pollution from industrial enterprises, as well as the risks of disruption of operation and flooding of mines. The armed conflict in the East of Ukraine led to serious environmental consequences – it is the pollutio... see more
