Gilsonite Consumption Usage:

1. Asphalt and Road Paving Sector
Formany years, Gilsonite has been used in the oilfield as an additiveindrilling fluids. Gilsonite, in various grades and formulations, hasbeenused to combat borehole instability problems, providelubricity,especially in highly deviated holes, and more recently as abridgingagent to combat differential pressure sticking and provide alawinvasion coring fluid. It has been well documented thatappropriatelyformulated Gilsonite products can minimize hole collapsein formationscontaining water-sensitive, sloughing shales and reducestuck pipeproblems by forming a thin wall cake and an inter-matrixfilter cake.
Gilsonite products are currently being widely used inwater based, oilbased, and synthetic based mud systems worldwide.Blended Gilsonite hasproved to be very effective in all water-basedsystems, with theflagship product in this line being Bore-Plate(R)Shale Stabilizer.
2. Oil Sector
Gilsonite is used in drillingmud fluids and oil well cementing.Gilsonite, in a range of softeningpoints and particle sizes, is astandard ingredient in oil-baseddrilling muds used in shales and otherdifficult geological formations.The addition of specially-treatedGilsonite to water-based drillingfluids helps minimize hole washout bystabilizing troublesome shales,and seals off highly permeable sandswhile reducing torque and drag. Theaddition of Gilsonite to oil wellcements reduces slurry weight withoutloss of compressive strength andacts as an effective bridging andplugging agent to seal fractures inweak formations while cementing
3. Asphalt and Road Paving Sector
Gilsoniteis used as a performance-enhancing agent for asphaltmixes.Gilsonite-modified paving mixes achieve higher PG gradesandincorporate perfectly into the asphalt blend with no need forhighshear milling as is the case with many othermodifiers.Gilsonite-modified asphalts have higher stability, reduceddeformation,reduced temperature susceptibility and increased resistanceto waterstripping than non-modified asphalts. Gilsonite is also used tomakeboth solvent-based and emulsion pavement sealers withsuperiorappearance and weathering properties.
4. Foundry Sector
Gilsoniteis combined with coal and other ingredients as an additive infoundrysands to insure the quality of the molded part by improvingmold releaseand the overall finish of metal castings.
5. Chemical Products Sector
Gilsonitecombines with many other chemicals and materials that takeadvantage ofits unique physical and chemical properties. Binder andcoatingapplications in metallurgical, wood product, refractary andotherindustries further demonstrate the versatility and usefulness ofthisremarkable material.
6. Inks and Paints Sector
IranianGilsonite Resin is widely used as the primary carbon blackwetting agentfor black news inks and headset and gravure inks. IranianGilsoniteResin competes advantageously with petroleum-basedhydrocarbon resins,phenolic resins and metal resinates, all of whichit can complement orreplace to various degrees. Various concentrationsof Iranian GilsoniteResin are used to manufacture law-rub-off newsinks with superior glossand tack properties. Special grades ofGilsonite called Selects are alsostandard ingredients in black inkformulations and are used as additivesin asphaltic paints andvarnishes.
