Silica Fume For the OIL and GAS industry

Silica fume can be used for a primary placement of grout as a hydraulic seal in the well bore, or secondary applications such as remedial operations including leak repairs, splits, closing of depleted zones. The addition of silica fume enables a well to achieve full production potential. The silica fume works as a blocking effect in the oil well grout, which prevents gas migration and other advantages to enhance well productivity.

In recent years, microsilica have been widely used in various fields, especially in oil well cementing, due to the addition of silica fume, so as to improve anti high temperature strength decline performance of mud solidified, is widely used in high temperature wells, geothermal wells and thermal recovery wells, the general use amount is 8%-15%.
