background and objective: edible, biodegradable films, by acting as barriers to control the transfer of moisture, oxygen, lipids, and flavours, can prevent quality deterioration and increase the shelf life of food products. on the other hand, regarding edible film capacity in transferring food additives, extending shelf-life of food products could be considered. so by adding antimicrobial-antio...

Early detection of oil spill events is the key to environmental protection and disaster management. Current technology lacks the sensitivity and specificity in detecting the early onset of a small-scale oil spill event. Based on an infrared oil-water contrast model recently developed, we propose a novel nonscanning computational infrared sensor that has the potential to achieve unprecedented de...

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 ability to prepare solid surfaces with well-controlled superhydrophobic and superoleophilic properties is of paramount importance to water-oil separation technology. Herein, we successfully prepared superhydrophobic-superoleophilic membranes by single-step deposition of polystyrene (PS) nanofibers onto a stainless steel mesh via electrospinning. The contact angles of diesel and water on the...

Normal Stresses and Interface Displacement: Influence of Viscoelasticity on Enhanced Oil Recovery Efficiency — One of chemical Enhanced Oil Recovery (EOR) methods consists in injecting aqueous solutions of polymers into the reservoir in order to improve mobility ratio between the injected fluid and the remaining oil. This “polymer flooding” process is usually only characterized with the low she...

In 2016, the Kingdom of Saudi Arabia (KSA) announced its Vision 2030 strategic plan incorporating major changes to the economic structure of the country, in­ cluding an intention to deploy 9.5 GW of renewable energy in an effort to reduce the penetration of oil in the electricity generation system. This paper assesses the macroeconomic impact of such changes in the KSA, coupled with reductions ...

The objective of this paper is to prospect and analyse the main challenges faced when defining and building virtual reality workspaces for Exploration & Production oil & gas activities. Initially, we classify and describe the different challenges. Then, we present the main activities in the oil & gas industry that use this technology.

a new chemical compound is developed at petroleum university of technology to enhance therecovery of the free imbibition process and simultaneously hinder asphaltene precipitation. thecompound is tested on heavy oil samples from marun oil field, bangestan reservoir. the effects ofthe chemical compound on viscosity, hydrocarbon composition, and average molecular weight ofthe heavy oil are invest...

The genus Rhodococcus is known for its ability to degrade various xenobiotic compounds. Rhodococcus sp. strain P14 isolated from crude oil-contaminated sediments can degrade mineral oil and polycyclic aromatic hydrocarbons (PAHs). The draft genome sequence of Rhodococcus sp. P14 was obtained using Solexa technology, which provided an invaluable genetic background for further investigation of th...
