CARBONITE
Carboniteis a mined hydrocarbon resin, glossy black asphaltic with a low
SG (1.05-1.06). It occurs in very pure states compared to other asphalts and has softening
points ranging from 360° to 450°F (180° to 232°C). It is produced specifically as an additive for
Drilling Fluids and Cementing applications. It is a competitive alternative for U.S. mined
gilsonite. Carbonite is a product of HydroCarbNite SAS of France.
Carbonite is chemically inert, insoluble in water, providing a deformable
solid in drilling fluids and cement. It possesses formidable technical advantages over other
products at a signifiant reduction in cost
Carbonite is produced in 3 temperature ranges. It is a high molecular
weight hydrocarbon resin with a large molecular weight distribution, therefore its softening
point is much higher compared to other types of polymers, allowing molecular deformation to
occur gradually as it approaches its softening point and instead of completely melting into a
low-viscosity liquid, Carbonite remains as a high viscosity liquid even after 20 degrees above
its softening point.
Technical characteristics of Carbonite in Drilling Fluids:
a) Reduces HTHP Fluid Loss
b) Improves Filter Cake Quality
c) Stabilizes Shales
d) Helps Prevent Differential Sticking
e) ReducesTorqueandDrag
f) Effective in a High Temperature Environment
g) Strengthens the Well Bore
CarboniteCarbonite is a premium grade shale control and HTHP fluid loss
additive tested in major mud labs around the globe validating its superior quality and efficiency
compared with other mined gilsonites.
CarboniteCarbonite is micronized for maximum efficiency in particle size
distribution to improve the filter cake qualit. Only ≤ 5% is retained on a 200 mesh screen, ≤ 10%
on a 230 mesh screen and 0% on a 150 mesh screen.
