ABSTRACT:
A cement includes a cement mixture and a permeable, micro-cluster silica material present in an amount from about 10 percent to about 30 percent by weight of the cement mixture. The cement blend may be used in casing a borehole when appropriate fluid loss agents are included in the cement blend. Additionally, a cement additive is added to a cement mixture to provide the cement blend. This cement additive can be formulated in a kit form.
