What is Gilsonite?

Gilsonite is a lightweight and black organic substance found in nature which is formed through petroleum solidification. Weathered Gilsonite takes on a dull, black look similar to coal, while freshly broken Gilsonite has a shiny surface reminiscent of obsidian. It is commonly referred to as natural asphalt, asphaltite, uintaite, or asphaltum. Gilsonite can dissolve in aliphatic, aromatic, and chlorinated hydrocarbon solvents, including petroleum asphalt. It can also be used for enhancing the hardness of softer petroleum products. In its solid form at ambient temperature, Gilsonite appears shiny and black, resembling the mineral obsidian. In high temperatures, the shape of the Gilsonite will transform into liquid and paste form. It is brittle and can be effortlessly crushed into a dark brown powder.

The history and origin of Gilsonite: A journey through time

The exploration of Gilsonite traces back to the 1860s when Samuel H. Gilson, a mining engineer, stumbled upon it in the Uinta Basin. In 1888, Samuel H. Gilson and his partner founded the initial enterprise to extract and commercially sell it. This substance is a fossil resource found naturally and resembles petroleum-based asphalt, containing a significant amount of asphaltene. Its structure has a higher proportion of nitrogen compared to oxygen, resulting in unique characteristics such as surface wetting and resilience against oxidation caused by free radicals.

Initially employed for asphalt road paving, paints, and waterproofing for timbers, Gilsonite swiftly found its way into various industrial applications. Its usage expanded beyond artworks as it became an additive in asphalt paving, enhancing durability and resistance against deformation. Moreover, it found utility in the manufacturing of roofing materials, ink, adhesives, and numerous other products. Presently, the drilling industry heavily relies on Gilsonite, incorporating it as a vital component in drilling fluids.


An overview of its physical and chemical characteristics

Gilsonite has above 80% carbon content and a low carbon/hydrogen ratio which shows a high molecular condensation. It contains 15% hydrogen, 5% nitrogen, oxygen, sulfur, and metal elements as well as 15-30% volatile organic compounds. Gilsonite’s physical and chemical properties range from a combination of refinery bitumen and carbon.

From a chemical perspective, Gilsonite consists of intricate blends of hydrocarbons encompassing alkanes, alkenes, and aromatics. Additionally, it contains minute quantities of sulfur, nitrogen, and oxygen. Its molecular composition exhibits extensive cross-linking, contributing to its distinctive set of physical characteristics.

Industrial applications of Gilsonite: From asphalt to drilling fluids

Gilsonite finds extensive utility across various industries, including asphalt and drilling. In the realm of asphalt production, it serves as an additive that enhances performance by bolstering the longevity, flexibility, and resistance to deformation of asphalt pavements. Furthermore, it plays a significant role in the manufacturing of roofing materials like shingles and waterproofing membranes.

Within the drilling industry, Gilsonite assumes a crucial position as a vital component within drilling fluids. Its presence in these fluids facilitates lubrication, regulates fluid loss, and enhances the stability of the borehole walls. Additionally, it acts as a bridging agent, aiding in the sealing off of formations and preventing the undesired influx of drilling fluids into the formation.

Environmental benefits of Gilsonite: A sustainable alternative to petroleum products

Compared to other petroleum-based products, Gilsonite has several environmental benefits. It is a naturally occurring resource that is renewable and sustainable. It also has a lower carbon footprint than other petroleum-based products, making it an eco-friendlier option.

Using Gilsonite in the industry can also help reduce greenhouse gas emissions by improving the durability and lifespan of asphalt pavements, which reduces the need for frequent repairs and replacements.

How Gilsonite is mined and processed

Gilsonite is mined using both underground and surface mining techniques. In underground mining, vertical shafts are used to access the deposits, while in surface mining, open pits are used. Once the ore is extracted, it is transported to a processing facility where it is crushed, screened, and classified.

The refining process

It involves heating the crushed ore to a high temperature to remove the volatile components and leave behind the solid Gilsonite. The resulting product is then crushed and ground to a fine powder and classified according to its particle size and purity.

The global market for Gilsonite: Trends, challenges, and opportunities

Gilsonite is a globally traded commodity with a market size of approximately $350 million. The largest producers of Gilsonite are the United States and Iran, which together account for over 90% of the world’s supply. Other significant producers include China and Turkey.

The demand for Gilsonite is driven by the construction and drilling industries, which use it for a variety of applications.
