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.
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.
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.
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.
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.
