Cementing

GILSONITE® UINTAITE IS AN EFFECTIVE LOST CIRCULATION MATERIAL THAT ASSURES ZONAL ISOLATION AND REDUCES ENVIRONMENTAL RISK.

As the challenges presented by today’s wellbore configurations increase, a properly designed cementing process is critical to keeping the wellbore isolated, protected and environmentally sound.

Cementing

For more than 50 years, the industry has depended on Gilsonite® uintaite as a lost circulation material and a critical component for primary cementing operations in some of the world’s toughest drilling environments.

Adding Gilsonite® during cementing operations enhances the characteristics that are critical to effectively cementing the casing, isolating hydrocarbon formations and preventing annular gas flow.

With its unique physical and chemical properties, Gilsonite® uintaite provides a range of important benefits in slurry and set cement that are unmatched by any other single additive.

Cement slurry benefits

  • Increases yield
  • Reduces slurry weight
  • Controls free water
  • Lowers slurry water ratio
  • Promotes favorable rheologies resulting in lower ECDs
  • Prevents lost circulation
  • Scours wellbore/enhances mud removal

Set cement benefits

  • Maintains compressive strength, unlike coal or fly ash
  • Increases flexibility
  • Reduces cracking
  • Heals microfissures
  • Reduces permeability
  • Strengthens bond to the formation and the casing
  • Reduces environmental risk
  • Assures zonal isolation

Gilsonite® eliminates the problems of free water
By controlling free water, Gilsonite® uintaite helps stabilize slurry and eliminates the need for – and cost of – additional free-water-control agents. As a lost circulation material, it also improves zonal isolation by preventing water channeling on the upper side of the wellbore.

Lost circulation material Gilsonite controls free water, improves zonal isolation

Self-healing properties help maintain zonal isolation
Gilsonite® uintaite is flexible, deformable, swellable, impermeable and non-porous. These characteristics give Gilsonite® self-healing properties that can plug induced microfissures in the cement sheath.
