Oil & Gas- Gilsonite is proven under pressure
Gilsonite in Oil & Gas
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 increase 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 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.
Gilsonite in oil & 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 gilsonite additives are ordinarily regarded as being of the primary character.

Also, Gilsonite use in Mud drilling according to FLC ” Filtrate Loss Control ” or ” Fluid Loss Control ” in oil base mud.
For many years Gilsonite has been used in the oilfield as an additive in drilling fluids. Gilsonite, 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 Gilsonite has proved to be very effective in all water-based systems, with the flagship product in this line being Bore-Plate(R) Shale Stabilizer.
