Is Bitumen Organic Matter?

Bitumen and solid bitumen are secondary hydrocarbon products that are found in most source and tight reservoir rocks. They are formed during different stages of the post-burial organic matter evolution continuum. … Pre-oil and post-oil bitumens were long recognized by Taff4, Brooks5, and Silverman6.

Asphalt is a mixture of aggregates, binder and filler, used for constructing and maintaining roads, parking areas, railway tracks, ports, airport runways, bicycle lanes, sidewalks and also play- and sport areas. Aggregates used for asphalt mixtures could be crushed rock, sand, gravel or slags.

What is the difference between kerogen and bitumen?

Kerogen—the organic matter that is solid and insoluble in organic solvents—is a key component of organic-rich mudstones. … Kerogen is consumed during thermal maturation, whereas bitumen is an intermediary formed at low maturity from kerogen and consumed at higher maturities in formation of oil and gas.

Is bitumen a fuel?

Bitumen (sometimes referred to as asphalt or tar) is a specialist fuel grade, typically only produced in about 65% of refineries around the world and with a yield of only 3-4% of the total crude slate. Bitumen is a unique form of petroleum that we could not live without.

What are the uses of bitumen?
