The area is currently the site of significant heavy crude oil and natural gas production.

Heavy crude oils provide an interesting situation for the economics of petroleum development.

Venezuela is the second largest reserves of light and heavy crude oil in the western hemisphere.

The company also produces conventional oil, heavy crude oil, and natural gas.

Steam injection is an increasingly common method of extracting heavy crude oil.

Heavy crude oil is a sister resource to bitumen.

There are two main types of heavy crude oil:

Heavy crude oils have a density (specific gravity) approaching or even exceeding that of water.

As a result, heavy crude oil is more difficult to refine into lighter products such as gasoline.

To be economic, these projects rely on substantial differences in pricing ("differentials") between light and heavy crude oil.

Heavy crude oil is closely related to natural bitumen from oil sands.

Peregrino is a heavy crude oil of 13.

Light crude oil, which is less viscous than intermediate and heavy crude oil.

In fact, while the price of jet fuel was rising so sharply, heavy crude oil was in surplus.

Heavy crude oils do not disperse as well as light to medium weight oils.

Western Canadian Select is one of North America's largest heavy crude oil streams.

Oil wells and batteries in the countryside evidence heavy crude oil extraction in the region.

Production, transportation, and refining of heavy crude oil present special challenges compared to light crude oil.

Heavy crude oils also carry contaminants.

These deposits of bitumen or heavy crude oil have the ability to generate about 12 to 19 billion barrels from a number of prominent sites.

Thermal simulators (most commonly used for heavy crude oil applications) add conservation of energy to this list, allowing temperatures to change within the reservoir.

Heavy crude oils usually contain high concentrations of sulfur and several metals, particularly nickel and vanadium.

Heavier crude oils contain a higher proportion of heavy hydrocarbons composed of longer carbon chains.

Chinese refineries would still have to be refitted since most cannot process the heavy crude oil exported by Venezuela, an adjustment that could take several years.

We were surprised at this figure of 25.7 API that was pulled out for the definition of heavy crude oil.
