Conventional crude oil, as the current dominant energy source, is an unrenewable resource. Despite the improvement of alternative energy technology such as wind and solar, there is still a large gap between the capability of these systems for supplying energy and global energy requirements. Therefore, until technological innovations facilitate sufficient energy generation through alternative fu...

The bioemulsifier V2-7 is an exopolysaccharide (EPS) synthesized by strain F2-7 of Halomonas eurihalina and it has the property of emulsifying a wide range of hydrocarbons i.e. n-tetradecane, n-hexadecane, n-octane, xylene mineral light and heavy oils, petrol and crude oil. Characteristics of exopolysaccharide V2-7 produced in media supplemented with various hydrocarbons (n-tetradecane, n-hexad...

The routine surveillance of oil spills in major ports is important. However, existing techniques and sensors are unable to trace oil and micron-thin oil films on the surface of seawater. Therefore, we designed and studied a coastal-mounted sensor, using ultraviolet-induced fluorescence and fluorescence-filter systems (FFSs), to monitor oil spills and overcome the disadvantages of traditional su...

The purpose of this study is to enhance the quality heavy oil through refinement using aquathermolysis with simultaneous injection steam and thermally stable nonionic surfactants (NS). To achieve this, NS R-PPG type was synthesized, optimal product structures were characterized infrared (IR) methods. Furthermore, thermal stability synthesized investigated in line requirements for used applicati...

In this work, the effect of distilled water, a biodiesel viscosity reducer, and commercial nonionic surfactant on apparent permeability clay-sand cores through analysis contact angle, linear swelling, porous media fluid flow for northern Mexico crude oil was evaluated. The results showed that clay content influences angle values having lower wettability in rocky medium. addition produces moveme...

Microbial Enhanced Oil Recovery (MEOR) is a tertiary oil recovery method that utilizes microbes to enhance oil production. This research was focused on the isolation and characterization of indigenous bacteria from a South Sumatra’s oilfield which were able to degrade heavy crude oil and decrease oil viscosity. The total of 33 colonies were successfully isolated based on sequential isolation me...
