Rheological Properties of Heavy Oils and Heavy Oil Emulsions
Energy Sources, 1996In this study, we investigated the effects of a number of process variables such as shear rate, measurement temperature, pressure, the influence of pretreatment, and the role of various amounts of added water on the rheology of the resulting heavy oil or the emulsion.

Rheology of Heavy Oil Emulsions
Proceedings of SPE/PS-CIM/CHOA International Thermal Operations and Heavy Oil Symposium, 2005Abstract Water is invariably produced with crude oil. If there is enough shear force when crude oil and produced water flow through the production path, stable emulsions may be formed. This scenario may particularly be present during the production of heavy oils where steam is used to reduce the viscosity of heavy oil or in cases where ...

Interaction of Heavy Crude Oil and Nanoparticles for Heavy Oil Upgrading
2020The relevance of nanotechnology in the field of energy resources has been growing at a swift pace. The term ‘catalyst’ has a whole new outlook since the foundation of nanomaterials in process industries. Nanocatalysts, in general, play a vital role in the improvement of resource handling and process efficiency.

Compositional Based Heavy Oil Viscosity Model for Kuwaiti Heavy Crude Oils
SPE Heavy Oil Conference and Exhibition, 2016Abstract Previously published models for predicting heavy oil viscosity based on the composition or API gravity are extensively evaluated to ascertain their effectiveness with 28 newly collected Kuwaiti heavy oil samples from different locations.

Applying Canadian Heavy Oil Technology to an Argentine Heavy Oil Reservoir
Canadian International Petroleum Conference, 2000Abstract With the exception of the highly developed world class deposits in Venezuela, production of heavy oil is not common in South America. YPF S. A. (now Repsol YPF), the largest oil producer in Argentina, operated its Cerro Fortunoso heavy oil reservoir for a number of years using techniques primarily adapted ...

Fuel, 1989
Abstract The hydropyrolysis of four heavy oils and several model compounds was studied under the following reaction conditions: temperatures from 500 to 1000 °C; pressures from 1.1 to 6.0 MPa; residence times from 15 to 60s; and hydrogen/oil ratios from 0.2 to 3.0 g/g. The oils were converted into gas, liquid and carbonaceous solid. The reactivity of

Characterization of Heavy Oils and Heavy Ends
2003Current global reserves of conventional crude oils are estimated at approximately 1,000 billion barrels (1 bn bbls = 109), while extra heavy crude oil (XHC) plus tar sand in place volumes are estimated at around 7,000 bn bbls.1 From the former estimation, Canada and Venezuela respectively, appears to be the leading countries in tar sand and XHC oil ...
