1. Mobilizing heavy oil and bitumen The key to producing heavy oil is to reduce oil viscosity, and that is best accomplished by heat. Other methods have been proposed, but are much less effective. At the relati
A method is proposed for calculating the kinematic viscosity of commercial heavy fuel oil at 100°C on the basis of mixing indices and with allowance for the equivalent kinematic viscosity of tar, which is represented by the product of the kinematic viscosity of the latter at 100°C by a ...
The ship engine was operated using two different types of fuels, heavy fuel oil (HFO) and diesel fuel (DF). Sampling of CCs was performed from diluted exhaust using cartridges and impingers. Both sampling methods involved the derivatization of CCs with 2,4-Dinitrophenylhydrazine (DNPH). The ...

First, the design of the HyFiT fuel process flexibly closes the carbon cycle by employing biomass or carbon dioxide as feedstock, while being scalable through mature technologies. Second, fuel testing shows that HyFiT fuels comply with global fuel standards. Material compatibility is demonstrated for...
Residual oils, high viscosity and large sulfur content petroleum products from the refining process of crude oil, are receiving increasing interest in pre-combustion carbon capture applications. Gasification is a promising technology to convert such complicated hydrocarbons into syngas. Pyrolysis and combust...
oil viscosity, and gas saturation. A mathematical expression for the effective permeability was developed based on experiments, where the viscosity of foamy oil is assumed to be approximately equal to the saturated oil under equivalent conditions. The compressibility coefficient of foamy oil is treated...

Despite being the most widely applied thermal process for heavy oil production, steamflooding has well-known limitations including marginal efficiency, intensive energy and water demands for steam, and emissions from fossil fuel combustion [13], [14], [15]. Moreover, the viscosity reduction ...
The inventors discovered that a low-viscosity, O/W type super-heavy oil emulsion fuel can be prepared using 100 parts (weight standard, same for all to follow) of super-heavy oil, 30-80 parts, and preferably 33-50 parts, of water, 0.01-4 parts by weight of an anionic surface active ...
