IntegraGuard Spacers

IntegraGuard products and systems are efficient, cost-effective solutions that have been carefully engineered for safe, easy application and consistent, reliable results. IntegraGuard products are proven in a variety of applications including vertical, deviated and horizontal wells

IntegraGuard Star

IntegraGuard Star

Well-proven cement spacer solution for eliminates cement losses associated with cementing operations. This system uses advanced fluid and particulate technologies that create a barrier at the formation face, effectively strengthening the wellbore, minimizing fluid invasion and sealing fluid loss paths. The spacer system provides temperature stability, fluid compatibility and the capability to design specific density and viscosity expected from a premium cement spacer.

IntegraGuard Star spacer systems can also be used in stand-alone lost circulation situations. In extreme situations, additional IntegraGuard Plus sealant can be added to enhance the system sealing capability.

Applications

  • Primary and remedial cementing operations
  • Vertical, deviated and horizontal wells
  • High permeability, unconsolidated and fractured formations
  • Low-fracture gradient wells

Features and Benefits

  • Effective mud removal and displacement efficiencies
  • Improves mud/spacer and spacer/cement compatibilities
  • Reduces fluid filtrate losses and potential damage of the formation
  • Easily prepared and pumped with conventional cementing equipment
  • Cures or reduces cement lost circulation

IntegraGuard Ultra

Improves the cement bond to the formation by effectively cleaning the wellbore. Preceding the cement, this spacer enhances mud displacement efficiency and prevents cement slurry contamination. IntegraGuard Ultra spacer polymer is typically provided as a liquid concentrate, making it easy to prepare on the rig site.

Applications

  • Primary and remedial cementing operations
  • Vertical, deviated and horizontal wells

Features and Benefits

  • Improves mud cleanup for better cement bonding
  • Improves bonding to the formation and pipe
  • Easily prepared and pumped with conventional cementing equipment
  • Compatible with most water- and oil-based drilling muds by varying the surfactant packages
  • Effective in a wide range of good temperatures

IntegraGuard Rheo

Effectively displaces drilling fluid in the annulus, providing optimal conditions for cement placement. This water-based spacer enhances effective mud removal by providing adequate friction pressure and enhanced mud/spacer/cement compatibilities, helping to improve the cement bond.

IntegraGuard Rheo spacer systems are stable over a wide temperature range, ensuring minimal weighting-agent settling, even in long horizontal applications. Its rheological properties can be easily adjusted to meet the well requirements by altering polymer concentrations, ensuring ideal friction hierarchy and reducing cement channeling. IntegraGuard Rheo spacer polymer is available as a liquid concentrate, making it easy to prepare on the rig site.

Applications

  • Primary and remedial cementing operations
  • Vertical, deviated and horizontal wells

Features and Benefits

  • Effective mud removal and displacement efficiencies
  • Provides proper friction pressure hierarchy
  • Improves fluid compatibilities
  • Stable over a wide temperature range
  • Allows for rheological versatility for specific well conditions
  • Easily prepared and pumped with conventional cementing equipment

IntegraGuard EZ

Cement spacer system enhances mud displacement and prevents cement slurry contamination. It is effective for a wide range of bottomhole temperatures and can be designed with densities up to 18 ppg.

Applications

  • Primary and remedial cementing operations
  • Vertical, deviated and horizontal wells
  • Wells with circulating temperatures up to 275°F (135°C)

Features and Benefits

  • Enhances operational efficiency and cost effectiveness
  • Flexibility to adjust volumes and density at short notice
  • Viscosity can be varied to optimize rheological hierarchy
  • Reduces wellsite equipment footprint
  • Easily prepared and pumped with conventional cementing equipment

IntegraGuard Multi

Pozzolanic scavenger spacer pumped ahead of the cement slurry in sufficient volume to displace the drilling mud to the surface, which can be reused or reprocessed, leading to a notable reduction in the overall well cost.

The density and viscosity of IntegraGuard Multi spacer systems are engineered to provide the required fluid stability, friction pressure and density hierarchy for well control and fluid displacement. Set times of the systems are adjusted to ensure adequate placement time. Fluid compatibility and wellbore conditioning are further enhanced by preceding IntegraGuard Multi spacer with conventional water-based spacer.

Applications

  • Non-aqueous drilling fluids recovery
  • Primary cementing
  • Oil and gas wells
  • Vertical, deviated and horizontal wells

Features and Benefits

  • Cost-effective recovery of non-aqueous drilling fluids at high volumes
  • Improves wellbore stabilization and reduced casing corrosion
  • Enhances zonal isolation and wellbore integrity
  • Engineered to match wellbore conditions
  • Prepared and pumped with conventional cementing equipment
