Heavy crude oil can contain a high paraffin and asphaltene content that reduces flow and lowers production rates. Molecules can also cause oil to become viscous and difficult to transport. Clariant's asphaltene inhibitors and oil dispersants are designed to prevent agglomeration and reduce solid formations for higher flow volumes.
Devon's thermal heavy oil operations, located in the Athabasca oil sands in northeast Alberta, use an extraction process called steam-assisted gravity drainage (SAGD). Heat from a steam injection well liquifies very dense bitumen allowing it to migrate to a production well located beneath.
Heavy Oil. Large reserves of heavy oil, significant investment. Some of the world’s largest reserves are heavy oil reservoirs. With oil in place equal to the largest conventional oil fields in the Middle East, these large reserves are found in more than thirty countries around the globe, but few of these deposits have been developed extensively.

2019-6-10 · The Xinjiang branch of PetroChina, China's largest oil and gas producer, said it had so far churned out more than 100 million tons of heavy crude oil, thanks to its innovative technologies.
2019-5-2 · Heavy oil is a liquid produced by refining crude oil in an oil refinery. It can be processed into light oil and lubricant. Solid fuel and flamethrower ammo can also be created from heavy oil. It is more efficient to process heavy oil into light oil before creating solid fuel from it.
The generic term heavy fuel oil (HFO) describes fuels used to generate motion and/or fuels to generate heat that have a particularly high viscosity and density. In the MARPOL Marine Convention of 1973, heavy fuel oil is defined either by a density of greater than 900 kg/m³ at 15°C or a kinematic viscosity of more than 180 mm²/s at 50°C.
That drives up demand for heavy sour crude, just like the oil produced in Alberta. The exploding supply of light shale oil and declining output of heavy oil from Mexico and Venezuela means US refineries are becoming increasingly more reliant on Canadian heavy oil and have no need to import light oil

Rapid cleanup of heavy oil spills is always considered a great challenge because conventional porous oil sorbents cannot efficiently remove them due to the high viscosity of heavy oil (>10 3 mPa s). In this work, we take advantage of the photothermal effect to heat heavy oil by using sunlight as the energy source to significantly reduce its viscosity and thus to achieve a fast heavy oil cleanup.
2019-6-4 · Since the 1960s, heavy fuel oil (HFO) has been the king of marine fuels.
