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 ...

Abstract Heavy or extra heavy crude oils cannot be transported by pipeline without a prior reduction of their viscosity. This is commonly obtained by blending the oil with light hydrocarbons. In that case, the resulting viscosity of the mixture depends only on the dilution rate, and on the respective viscosities and densities of the oil ...

THE BLACK OIL MODEL FOR A HEAVY OIL RESERVOIR
Proceedings of International Meeting on Petroleum Engineering, 1986ABSTRACT In a real black oil reservoir, especially in a heavy oil reservoir, the density, viscosity and other fluid properties of the oil vary both horizontally and vertically from point to point in the formation. For example, formation oil viscosity may vary several times and even more from the top of the formation to the water-oil ...

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

Abstract Although vast resources of heavy crude oil have been known to exist in west-central Saskatchewan for many years, until recently these resources have remained on the sidelines while the better quality crude oils of the southern part of the province were the focus of the oil industry. In recent years, however,
