The majority of global petroleum is in the form of highly viscous heavy oil. Traditionally heavy oil in sands at shallow depths is accessed by large scale mining activities. Recently steam has been used to allow heavy oil extraction with greatly reduced surface disturbance. However, in situ thermal recovery processes can generate hydrogen sulphide, high levels of which are toxic to humans and c...

In this paper, we report a theoretical study of transient squeezing flow through thin porous gap driven by an oscillating boundary. The process is governed the viscous, inertial, and Darcy effects. It shows that when depth increases, alternating dominance viscous inertial effects would increase oscillation velocity profiles. existence media effectively stabilizes fluid field. presented herein, ...

We present a lab-on-a-chip approach to informing thermal oil recovery processes. Bitumen - a major global resource - is an extremely viscous oil which is extracted by injecting steam underground in a process known as Steam Assisted Gravity Drainage (SAGD). Here, a microfluidic network saturated with bitumen provides a physical model of the SAGD reservoir; steam is injected into the chip, and th...

Jatropha curcas L. or physic nut belonging to family Euphorbiaceae is an all purpose, zero waste perennial plant. It is considered as a potential source of non-edible fuel producing plant along with its different medicinal properties and grows well in the tropical and subtropical climate in India. The seed contains 40-50 % viscous oil known as ‘curcas oil’. Petroleum based fuel are limited rese...

The more important parameters of force-feedback accelerometers are defined, sources of error are discussed and an outline is given of methods by which the accelerometers may be evaluated and calibrated. The emphasis is on treating the accelerometer as a self-contained component rather than as part of a navigation or other system. It is hoped that sufficient information on static and dynamic per...

The importance of heavy oil in the world market has increased over past twenty years as light reserves have declined steadily. high viscosity this kind unconventional results energy consumption for its transportation, which significantly increases production costs. A cost-effective solution long-distance transport viscous crudes could be water-lubricated flow technology. water ring separates oi...

A surface modification method for bonded polydimethylsiloxane (PDMS) microchannels is presented herein. Polymerization of acrylic acid was performed on the surface of a microchannel using an inline atmospheric pressure dielectric barrier microplasma technique. The surface treatment changes the wettability of the microchannel from hydrophobic to hydrophilic. This is a challenging task due to the...
