Gilsonite is a type of natural asphaltic materials which are widely used as an effective filtration agent additive in oil-based and water-based drilling fluids. Gilsonite may be used in normal or HTHP environments. Other functions of Gilsonite are shale inhibition, preventing seepage loss circulation and differential stuck reduction.

Gilsonite Usage In Road Construction and Asphalt PreparationIn road construction and asphalt preparation Gilsonite is used to increase the strength of asphalt against traffic and load, prevent deformation in hot weather, crack at low temperatures and also reduce the effects of moisture in the asphalt mixture. This mineral is a suitable modifier for refinery bitumens due to it's polymeric hydrocarbon material. The resistance of Gilsonite against acid and base and insolubility in water has caused it to be generally used in the preparation of asphalt and waterproofing insulation.
Gilsonite Mines In IranAreas with Gilsonite in Iran are mainly located in Kermanshah-Ilam provinces (especially Gilangharb city), Khuzestan and in some other areas such as Yazd have been observed to a limited extent. The existence of these vast areas demonstrates huge reserves of this product and the high capability of supplying Gilsonite in Iran. The geographical strip, where Iran’s Gilsonite supply mines are located, reaches Iraqi Kurdistan and Turkish Kurdistan, crossing the country’s borders.
Types of Iranian GilsoniteGilsonite originates from crude oil, which is formed after the gradual evaporation of light materials under the influence of four factors: time, heat, pressure, and special reactions. Main reactions in the production process are oxidation, sulfurization, polymerization and condensation. The product quality of these processes varies according to the type of reactions performed and the duration of the reactions (life of bitumen). So that bitumen is observed with liquid, semi-solid and hard physical states. Most of the Iran Gilsonites are long-lived, but in general they can be divided into two general categories:
- Relatively Pure Bitumen: This category is usually found in liquid and semi-solid form with less than 10% minerals. They also have a relatively large amount of volatiles. Examples of this type of Gilsonite (which the exact amount is not available) can be found in Khuzestan province. Their melting point is usually less than 300’F and their degree of penetration (Penetration) varies from 10 in terms of 0.1mm to very soft. Volatiles are less than 7% at 325F for 5 hours and up to 20% at 400F for 5 hours. Their solubility in CS2 is generally more than 90% and their values of C, H, N and S are about 82, 11, 2 and 2% by weight, respectively.
- Asphaltic Pyrobitomans: These Gilsonites are mostly with high melting points or non-melting point.
History of GilsoniteSamuel H. Gilson discovered Gilsonite in the early 1860s. Gilson, who worked in one of Iran’s oil regions, introduced this substance. Although this substance was discovered before him, he did a lot of research to process this product and tried to to use this substance for other applications. He first used this material to insulate wire cables and electrical insulation in general, as well as a coating for wooden pilings. He founded a company specializing in this field. Eventually, his promotional activities in the commercialization of this product led to this naming.
