... viscosity of the residual product. This reduction in viscosity is particularly important as the fuel oil produced has to meet certain specifications of viscosity, density and product stability. Increasing the severity of operating conditions results in increased conversion (defined as yield of fraction...

... Abstract One of the big issues for the development of extra heavy crude oil is transportation from the well head to the refinery or shipping facility. Conventionally, dilution is applied to reduce density and viscosity and diluted heavy oil is transported through pipelines. However, if diluent...

..." nanoparticle can alter the reservoir wettability and reduces interfacial tension resulting in additional recovery of entrapped oil from pores. Nanoparticles derived from transition metal oxides namely NiO, Co3O4 and Fe3O4 adsorbs asphaltenes from heavy oil which reduces the viscosity of heavy oil and enhances...

... surface active substance, acid, gas and so on, can decline the viscosity of oil considerably. Gum and asphaltene are components with biggest molecular weight and most serious polarity in heavy oils, meanwhile they are one of the main factors making the difficulty of oil recovery [2]. Usually, microbe can...

..." to transport oil from the wreck to a surface container, pumping the oil to the surface using a riser system and enclosing the whole wreck in a sarcophagus. Fuel viscosity at the wreck conditions was extreme (3 to 4 million centipoise). This, together with the depth, precluded the use of conventional techniques...
