Lump Gilsonite
Lump Gilsonite Description
Lump Gilsonite, or Natural Asphalt, Natural Bitumen is a natural, resinous hydrocarbon This natural asphalt is similar to a hard petroleum asphalt and is often called a natural asphalt, asphaltite, uintaite, or asphaltum. Natural asphalt is derived from the natural mutation of petroleum. This mutation happened a million years again under the influence of bacteria. This bacterial decomposition of petroleum resulted in reducing the content of saturated hydrocarbons, mainly n-alkalenes and light oil which became heavier and more viscous, taking the form of asphalt. It is a natural product a bituminous limestone in which carbonate of lime and pure natural asphalt are most intimately combined by a neutral agency. It is as bitumen created in the process of crude oil processing. It is native substances of variable color, hardness, and volatility, composed principally of the elements carbon and hydrogen and sometimes associated with mineral matter and essentially free of gas. Gilsonite is soluble in aromatic and aliphatic solvents, as well as petroleum asphalt. Due to its unique compatibility, gilsonite is frequently used to harden softer petroleum products. Gilsonite in mass is a shiny, black substance similar in appearance to the mineral obsidian. It is brittle and can be easily crushed into a dark brown powder. Gilsonite is found below the earth’s surface in vertical veins or seams that are generally between two and six feet in width but can be as wide as 28 feet.
Due to the narrow mining face, Gilsonite is mined today, much like it was
50 or 100 years ago. The primary difference is that modern miners use pneumatic chipping hammers and mechanical hoists.

Oil & Gas
Gilsonite In Oil & Gas
In the oil and gas industry, drilling fluids or liquids perform a diversity of operations that influence the drilling rapidity, efficiency, safety, and the cost of drilling operators. An important characteristic of gilsonite that makes it noteworthy for drilling fluid usages is its softening-point temperature. There are many types of drilling fluid systems available such as water-base muds, oil-base muds, stable foam muds, air, or gas base muds from which the right system may be chosen. In water-based muds, it is used as a shale-stabilizing additive and is difficult to evaluate unless tested at or above its softening point. In oil-based muds, it is used as a fluid-loss control agent.
With unmatched benefits in cementing and drilling fluids, Gilsonite is proven under pressure.
With a unique blend of strength, flexibility, bonding, and high-temperature capability, Gilsonite adds properties that increase performance in cementing and drilling fluids in a way no other single additive can.
Gilsonite is used in drilling mud fluids and oil well cementing. Gilsonite, in a range of softening points and particle sizes, is a standard ingredient in oil-based drilling muds used in shales and other difficult geological formations. The addition of specially-treated Gilsonite to water-based drilling fluids helps minimize hole washout by stabilizing troublesome shales and seals off highly permeable sands while reducing torque and drag. The addition of Gilsonite to oil well cement reduces slurry weight without loss of compressive strength and acts as an effective bridging and plugging agent to seal fractures in weak formations while cementing. Also, Gilsonite use in Mud drilling according to FLC ” Filtrate Loss Control ” or ” Fluid Loss Control ” in oil-base mud.
