Property
Gilsonite also named natural asphalt, which is similar to hard petroleum asphalt and is often called natural asphalt, it is soluble in aromatic solvents, as well as petroleum asphalt, due to its unique compatibility, gilsonite is frequently used to harden softer petroleum products.

Feature
? used in drilling mud fluids and oil well cementing
? the addition of special-treated gilsonite to water-based drilling fluids helps minimize hole washout by stabilizing troublesome shale’s
?the addition of gilsonite to oil well cements reduces slurry weight without loss of compressive strength and acts as an effective bridging and plugging agent to seal fractures in week formations while cementing.

Packaging and transport in sacked with three package, 25kg/sack. Kept away from fire, damage and leakage in store and transportation. Storage life is two years.
Property
Kol-rtd m cem can absorb on the surfaces of cement hydrate to inhibit contact with water and on the surfaces of crystal nucleis to prevent their increase. So it can retard hydrating of cement slurry.
