Sell Sodium Metasilicate

Sodium Metasilicate is an extender used to produce economical, low density cement slurry. When cementing pipe in many types of wells, it usually is desirable to place a long column of cement in the annulus up into the last string of pipe, or back to the surface. The use of a “neat” cement slurry to fill this column is, in most cases, impractical due to the economics of pumping large quantities of neat cement when its high-strength properly is required only at the very bottom of the casing. So typically, an extended cement slurry is pumped to fill most of the annulus, followed by a higher strength, higher density, neat cement slurry to fill the area around the bottom of the pipe. This extended, lower density slurry also helps reduce the hydrostatic head of along slurry column and prevent lost circulation across pressure-sensitive zones.
