Gilsonite in Oil and Gas
Gilsonite in the oil and gas industry, drilling fluids or liquids perform a diversity of operations that influence the drilling rapidity, efficiency, safety, and cost of drilling operators. An important characteristic of Natural Bitumen that makes it noteworthy for drilling fluid usage 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.
Gilsonite is used in drilling mud fluids and oil well cementing. Natural Bitumen, 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 Natural Bitumen to water-based drilling fluids helps minimize hole washout by stabilizing troublesome shales and sealing off highly permeable sands while reducing torque and drag. The addition of Natural Bitumen 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. 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 increases performance in cementing and drilling fluids in a way no other single additive can his versatile, multi-purpose additive is a naturally occurring hydrocarbon resin found only in northeastern Utah. Gilsonite has significant health, safety, and environmental (HSE) advantages over synthetic products. OSHA Material Safety Data Sheets classify Gilsonite as:
- Non-toxic
- Non-carcinogenic
- Non-mutagenic

Gilsonite in oil and gas well cementing is a highly developed technology. Cement-water slurries, with or without various additives, have been used for many years in cementing procedures carried out from time to time during the drilling of the productive life of a well. Cementing is often applied during drilling and completion procedures in connection with the protection of production zones, isolation and confinement of water zones, support of borehole wall, anchorage of the casing, and control of lost circulation not overcome by methods associated with the circulation of drilling mud. Such cementing procedures by Natural Bitumen additives are ordinarily regarded as being of the primary character.

Also, Gilsonite is used in Mud drilling according to FLC ” Filtrate Loss Control ” or ” Fluid Loss Control ” in oil-base mud.
For many years Natural Bitumen has been used in the oilfield as an additive in drilling fluids. Natural Bitumen, in various grades and formulations, has been used to combat borehole instability problems, provide lubricity, especially in highly deviated holes, and more recently as a bridging agent to combat differential pressure sticking and provide a law invasion coring fluid. It has been well documented that appropriately formulated Gilsonite products can minimize hole collapse in formations containing water-sensitive, sloughing shales and reduce stuck pipe problems by forming a thin wall cake and an inter-matrix filter cake.
Gilsonite products are currently being widely used in water-based, oil-based, and synthetic-based mud systems worldwide. Blended Natural Bitumen has proved to be very effective in all water-based systems, with the flagship product in this line being Bore-Plate(R) Shale Stabilizer.
