research in nanotechnology in the petroleum industry is advancing rapidly and an enormous progress in the application of nanotechnology in this area is to be expected. in particular, adding nanoparticles to fluids may drastically benefit enhanced oil recovery and improve well drilling, by changing the properties of the fluid, rocks wettability alteration, advanced drag reduction, strengthening ...

The continuous development of global economy with decreasing in available hydrocarbon sources and increasing discovery and extraction costs due to decrease in-situ oil and gas reservoir, displays the necessity of using new techniques for the improve rate of penetration and productivity in well. Nanotechnology has already contributed significantly to technological advances in the energy industri...

simultaneous capillary dominated displacement of the wetting and non-wetting phases are processes of interest in many disciplines including modeling of the penetration of polluting liquids in hydrology or the secondary migration in petroleum reservoir engineering. percolation models and in particular invasion percolation is well suited to characterize the slow immiscible displacement of two flu...

Two continuous mixture phase equilibrium algorithms which can be used for vapor-liquid equilibrium calculation involving verymany-component fluid mixtures are proposed. The algorithms are applied to the case of simulated gas-condensate systems with analytical results. The proposed continuous mixture techniques reduce the required computer time significantly While they retain accuracy of the pre...

This paper presents a new method to lubricate, cool, and evacuate chips in metalworking operations using supercritical carbon dioxide (scCO2). Water-based and straight oil metalworking fluids (MWFs) are currently being used to perform these functions even though they are characterized by high economic, occupational health, and environmental costs. Carbon dioxide above its critical temperature a...

A short primer on benzene, toluene, ethylbenzene and xylenes (BTEX) in the environment and in hydraulic fracturing fluids Dr Frederic Leusch and Dr Michael Bartkow, Griffith University – Smart Water Research Centre 17 Nov 2010 1. Some notes about concentrations Concentrations in water in this document are generally given as part‐per‐billion (ppb), equivalent to one microgram per litre (μg/L). ...

The industrial production of dimethyl ether (DME) is now about 10,000 ton/year in Japan, and DME has been mainly used as an aerosol propellant. Recently, DME can be directly synthesized from water gas, carbon monoxide and hydrogen, by use of a new type catalyst dispersed in fluids. So, a large amount of DME will be supplied in future. Considering the molecular structure, the physical properties...

The use of cutting fluids has played a vital role in machining operations lubrication and cooling. Most are mineral oil-based products that hazardous to the environment worker, cause severe diseases pollute environment. In addition, petroleum resources becoming increasingly unsustainable. Due environmental health issues, legislations have been established ensure consumption oil is reduced. Cons...

In spite of better performance, the disposal used petroleum-based cutting fluids threatens our environment. Thus, it is essential to develop eco-friendly for performing machining operations in industries. The main contribution this paper an fluid plain turning AISI 1010 steel which automotive industry. present work, boric acid (H3BO3) was mixed with neem seed. Neem seed oil easily available man...
