X-Prima™

X-Prima squeeze material is particularly effective in the remediation of severe lost circulation.

X-Prima high fluid loss squeeze provides deep sealing in natural and induced fractures, vugular formations, severely depleted sands and rubble zones. Usually, the application will take the form of a hesitation squeeze, whereby slurry is pumped into the loss zone and afterwards subjected to a series of low-volume injections. A waiting period follows each injection to allow dewatering and sedimentation to take place. As the thief zone is bridged and sealing begins, incremental increases in pressure force water out of the slurry, thus leaving a matrix of solids in place to plug the loss zone. Once circulation is restored, the annular face of the plug is sealed and reinforced through the deposition of solids. Where appropriate, the X-Prima slurry may be supplemented with additions of 5-10 lb/bbl of NewPlug™ medium or other proppant material to further enhance X-Prima’s effectiveness in sealing thief zones.

X-Prima squeeze material is mixed as a slurry and weighted to at least the density of the drilling fluid system. The material can be mixed with fresh water-, oil-or synthetic based drilling fluids, but it should be noted that the filtration rate and the quality of the plug matrix are negatively affected if oil or synthetic fluid is used in the slurry. It is generally recommended that the slurry volume be twice as much as the open hole volume, provided the mixing facilities have sufficient capacity. While the slurry can be pumped into the drill string using the rig pumps, it is advisable that a cement pumping unit be used for the displacement and hesitation squeeze sequence for maximum precision in managing injected volume and pressure.

Minimize exposure to dust. Store in a dry area. Use appropriate hygiene, clothing and personal protective equipment suitable for work being done. Review the SDS thoroughly before using this product.
