Cementing
Gilsonite® uintaite is a proven multifunctional additive for oilfield cementing applications. Used in both primary and remedial cementing operations, it improves slurry performance, strengthens set cement properties and helps preserve wellbore integrity throughout the life of the well. Operators rely on Gilsonite® to reduce slurry density, increase yield, improve flexibility and maintain long-term zonal isolation.
IMPROVES WELLBORE INTEGRITY
The quality of the cementing job is critical to maintaining long-term wellbore integrity. Gilsonite® strengthens the cement sheath through a unique combination of compressive strength, flexibility and self-healing properties that help preserve zonal isolation throughout the life of the well.
Benefits include:
- Supports compressive strength development
- Strengthens bonding to formation and casing
- Reduces permeability
- Helps maintain zonal isolation
- Reduces environmental risk associated with gas migration
- Increases flexibility

REDUCES SLURRY DENSITY & INCREASES YIELD
Gilsonite® acts as an effective cement extender that lowers slurry density while increasing yield. By displacing excess water and improving slurry efficiency, operators can reduce cementing costs without sacrificing performance.
Benefits include:
- Increases slurry yield
- Reduces slurry weight
- Provides lost circulation control
- Controls free water
- Improves rheology and lowers ECDs
- Reduces cost per barrel
Adding Gilsonite® uintaite to a 12.5 ppg slurry has been shown to increase slurry yield by approximately 8%, helping reduce cementing costs.
REPLACE COSTLY HOLLOW BEADS
Many low-density cement designs rely on hollow beads, but these materials can be expensive and susceptible to crushing during mixing or under downhole pressures. Gilsonite® G-BOND provides a cost-effective alternative that maintains low density while contributing important mechanical properties to the set cement.
Benefits of replacing beads with Gilsonite®:
- Lower cementing costs
- Crush-proof performance
- Reduced slurry density
- Increased flexibility
- Improved wellbore integrity
- Maintained compressive strength
Field testing has demonstrated slurry cost reductions exceeding 20% when Gilsonite® replaces a portion of hollow beads in low-density cement systems. Learn more >
IMPROVES LONG-TERM ZONAL ISOLATION
Unlike additives that only influence slurry properties, Gilsonite® continues to deliver benefits after the cement sets. Its flexibility, low permeability and self-healing behavior help maintain an effective barrier against fluid migration and gas intrusion over the life of the well.
Performance benefits include:
- Reduced permeability
- Reduced cracking
- Self-healing of microfissures
- Improved flexibility
- Greater resistance to stress cycling
