Gilsonite Powder General Description of Gilsonite Powder Gilsonite is naturally bulk form. At the request of the customer, it comes in the form of a conventional or micronized powder with various mesh. Micronized powder, as its name implies, is micron powder and most of its aggregation compound is typically below 20 microns.In order to establish […]
General Description of Gilsonite in Drilling Sector Gilsonite is used in drilling fluid loss control (FLC) 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 shale and other difficult geological formations. The addition of specially-treated Gilsonite to water-based drilling fluids […]
Natural Amorphous Graphite The term “amorphous graphite” is a contradiction in terms All graphite is crystalline by definition, therefore it is impossible for graphite to be amorphous. However, the term was applied due the anhedral (no visible crystallinity) morphology of this form of graphite. To the untrained eye a piece of amorphous graphite simply looks […]
Gilsonite as the Offshore Shale Stabilizer The laboratory analysis of four water-based muds (WBM) compared two blends of treated Gilsonite with sulfonated asphalt, which is a widely used shale stabilization and fluid loss control agent. In the series of tests, lignite/lignosulfonate, KCl, PHPA, and lime-based drilling fluids were examined on a triaxial tester that specifically […]
Sulfonated Asphalt Drilling Mud Additive Sulphonated asphalt is a lost circulation additive and used to plug a zone into which the drilling fluid is being lost, to prevent a complete loss of the drilling fluid is being lost, to prevent loss of the drilling fluid into the formation being drilled, and hence as lost […]
Summery Gilsonite resin is a naturally occurring, mined carbonaceous material classified as an asphaltite. For many years, Gilsonite has been used in drilling fluids as an additive to assist in borehole stabilizer. It has been well documented that this material works efficiently to minimize hole collapse in unstable shale sections. However, because Gilsonite is an […]

Gilsonite Deep Water Drilling Gilsonite in Deep Water Drilling has been proven safe and effective in more than 60 years of oilfield performance. Gilsonite is a safe, naturally occurring hydrocarbon resin with unique chemical properties. Added to drilling fluids, it increases performance and reduces cost in deepwater drilling while minimizing risk. Gilsonite eliminates deep […]
Gilsonite Asphasol Gilsonite in Asphasol is trade mark of Schlumberger to supply sulfonated asphalt Gilsonite Asphasol shale inhibitor is a partially water-soluble, sulfonated organic material developed for use in most water-based drilling fluids. Asphasol shale inhibitor contains no surfactants as do most water-dispersible products used in shale-control applications. Physical appearance: Black, free-flowing powder ph (2% […]
Gilsonite in Water Based Drilling Muds (WBM) It is essential in water-based mud to use an additive that can resolve in water. Gilsonite is not solvable in water by nature. Therefore a chemical procedure with Sulfur must be applied to the natural bitumen at a temperature between 100-140 degrees Celsius. This process is called Sulfonating […]
